| CVE-2026-6539 | 3 Don Ho, Notepad++, Notepad-plus-plus | 3 Notepad\+\+, Notepad++, Notepad\+\+ | 2026-07-28 | 4.4 Medium |
| Notepad++ 8.9.3 contains a format string injection vulnerability in the Find Results panel handler that allows attackers to cause denial of service and information disclosure by crafting a malicious nativeLang.xml language pack file. Attackers can distribute a poisoned language pack through community channels that triggers format string interpretation when a user performs search operations, leading to access violations and potential leakage of stack or register contents. | ||||
| CVE-2026-56111 | 2 Marlinfirmware, Marlinfw | 2 Marlin, Marlin Firmware | 2026-07-28 | 9.1 Critical |
| Marlin Firmware through 2.1.2.7, fixed in commit 1f255d1, when built with MESH_BED_LEVELING enabled, contains an out-of-bounds write vulnerability in the M421 G-code handler that allows attackers to corrupt firmware memory by supplying out-of-range X and Y grid indices. Attackers can send a single crafted G-code command via USB serial, network interface, or malicious gcode file to write an attacker-controlled 32-bit float value past the z_values array bounds, corrupting adjacent firmware variables and causing denial of service or firmware state corruption. | ||||
| CVE-2026-53994 | 2 Proftpd, Proftpd Project | 2 Proftpd, Proftpd | 2026-07-28 | 7.5 High |
| ProFTPD mod_sftp contains a heap-based buffer overflow reachable by an authenticated SFTP user. The fxp_packet_read() function accepts the attacker-supplied 32-bit big-endian SFTP packet length without a minimum sanity check. A value of 0 causes an unsigned subtraction elsewhere in the read path to underflow to approximately 4 GB. That oversized request reaches the core memory allocator, where the rounded size is computed in size_t but passed to new_block() as a 32-bit int; the low 32 bits of 0x100000000 are 0, so new_block() returns a small (~512-byte) block while the caller is told it received ~4 GB. The subsequent fill loop then streams attacker-controlled bytes past the end of the 544-byte allocation, producing an attacker-controlled heap buffer overflow. An authenticated user can crash the per-connection ProFTPD session child on demand with a single malformed SFTP packet (packet_len=0 followed by a body greater than approximately 544 bytes), producing reliable authenticated remote denial of service. Depending on heap layout and adjacent allocations, heap metadata corruption and further consequences beyond denial of service may be possible, though only denial of service is demonstrated by the supplied proof of concept. | ||||
| CVE-2026-49127 | 2 Musicpd, Musicplayerdaemon | 2 Music Player Daemon, Mpd | 2026-07-28 | 8.6 High |
| Music Player Daemon (MPD) before version 0.24.11 contains a stack buffer overflow vulnerability in the pcm_unpack_24be function in src/pcm/Pack.cxx that allows unauthenticated attackers to corrupt stack memory by triggering an off-by-one write in the PCM decoder plugin. Attackers can issue two MPD commands referencing a malicious HTTP audio source to cause the unpack loop to write 1366 entries into a 1365-entry buffer, overwriting four bytes past the array boundary with three attacker-controlled bytes from an HTTP response body, resulting in daemon termination or potential code execution. | ||||
| CVE-2026-48557 | 1 Spatie | 1 Laravel Media Library | 2026-07-28 | 8.8 High |
| Spatie Laravel Media Library before version 11.23.0 contains a file upload restriction bypass in FileAdder::defaultSanitizer(). The sanitizer checks only the final filename suffix, allowing double-extension filenames such as shell.php.jpg to bypass the blocklist, with pathinfo() preserving inner .php stems in saved filenames. The blocklist also omits executable extensions including .php6, .shtml, and .htaccess. The double-extension bypass requires a legacy Apache AddHandler configuration to achieve PHP execution; the incomplete blocklist bypass does not. | ||||
| CVE-2026-41934 | 2 Givanz, Vvveb | 2 Vvveb, Vvveb | 2026-07-28 | 8.8 High |
| Vvveb before version 1.0.8.2 contains an authenticated remote code execution vulnerability in the admin code editor that allows low-privilege authenticated users to execute arbitrary code through insufficient file extension restrictions, with the uploaded payload then executable via subsequent unauthenticated HTTP requests. Attackers with editor, author, contributor, or site_admin roles can write a malicious .htaccess file to map arbitrary extensions to the PHP handler, then upload PHP code with that extension to achieve unauthenticated remote code execution when the file is accessed via HTTP. | ||||
| CVE-2026-41931 | 2 Givanz, Vvveb | 2 Vvveb, Vvveb | 2026-07-28 | 5.3 Medium |
| Vvveb before version 1.0.8.2 contains an information disclosure vulnerability that allows unauthenticated attackers to obtain sensitive server information by triggering unhandled exceptions in the password-reset module. Attackers can access the admin password-reset endpoint to trigger a fatal error caused by a missing namespace import, which exposes the absolute server file path, internal class namespaces, line numbers, and source code excerpts through the debug exception handler rendered to unauthenticated requests. | ||||
| CVE-2020-37206 | 1 Nsasoft | 2 Nsauditor Sharealarmpro Advanced Network Access Control, Sharealarmpro | 2026-07-28 | 7.5 High |
| ShareAlarmPro contains a denial of service vulnerability that allows attackers to crash the application by supplying an oversized registration key. Attackers can generate a 1000-character buffer payload to trigger an application crash when pasted into the registration key field. | ||||
| CVE-2020-37040 | 1 Codeblocks | 2 Code::blocks, Code\\ | 2026-07-28 | 8.4 High |
| Code Blocks 17.12 contains a local buffer overflow vulnerability that allows attackers to execute arbitrary code by crafting a malicious file name with Unicode characters. Attackers can trigger the vulnerability by pasting a specially crafted payload into the file name field during project creation, potentially executing system commands like calc.exe. | ||||
| CVE-2019-25741 | 1 Mobatek | 1 Mobaxterm | 2026-07-28 | 9.8 Critical |
| Mobatek MobaXterm 12.1 contains a structured exception handling (SEH) based buffer overflow vulnerability in the username field of session files that allows remote attackers to execute arbitrary code. Attackers can craft a malicious MobaXterm sessions file with overflow data that triggers the vulnerability when imported and executed, enabling reverse shell execution with user privileges. | ||||
| CVE-2019-25655 | 3 Ctfer, Hdd, Hhdsoftware | 3 Monitoring, Device Monitoring Studio, Device Monitoring Studio | 2026-07-28 | 6.2 Medium |
| Device Monitoring Studio 8.10.00.8925 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long string to the server connection dialog. Attackers can trigger the crash by entering a malformed server name or address containing repeated characters through the Tools menu Connect to New Server interface. | ||||
| CVE-2019-25434 | 1 Nsasoft | 2 Nsauditor Spotauditor, Spotauditor | 2026-07-28 | 7.5 High |
| SpotAuditor 5.3.1.0 contains a denial of service vulnerability that allows unauthenticated attackers to crash the application by submitting excessive data in the registration name field. Attackers can enter a large string of characters (5000 bytes or more) in the name field during registration to trigger an unhandled exception that crashes the application. | ||||
| CVE-2018-25377 | 1 Socusoft | 1 Flash Slideshow Maker | 2026-07-28 | 8.4 High |
| Flash Slideshow Maker Professional 5.20 contains a buffer overflow vulnerability in the registration dialog that allows local attackers to execute arbitrary code by exploiting structured exception handling. Attackers can craft a malicious payload and paste it into the Name and Code fields of the Help > Register dialog to trigger a reverse shell with system privileges. | ||||
| CVE-2018-25147 | 2 Jenkins, Microhardcorp | 23 Credentials, Bullet-3g, Bullet-3g Firmware and 20 more | 2026-07-28 | 7.5 High |
| Microhard Systems IPn4G 1.1.0 contains hardcoded default credentials that cannot be changed through normal gateway operations. Attackers can exploit these default credentials to gain unauthorized root-level access to the device by logging in with predefined username and password combinations. | ||||
| CVE-2026-66035 | 2 Libssh2, Redhat | 2 Libssh2, Hummingbird | 2026-07-28 | 7.5 High |
| libssh2 through 1.11.1, fixed in commit 42e33d8, contains a pre-authentication heap buffer overflow vulnerability that allows a malicious SSH server to corrupt heap metadata in any connecting client by sending a packet with a packet_length smaller than the cipher's block size during Encrypt-then-MAC cipher negotiation. In the fullpacket() function in src/transport.c, the ETM path allocates a buffer of packet_length bytes but copies blocksize minus one bytes via memcpy, causing an overflow that on 32-bit glibc writes attacker-controlled bytes into an adjacent chunk's SIZE field, enabling tcache bin confusion, overlapping live objects, and function pointer overwrite during the session handshake before authentication. | ||||
| CVE-2026-66033 | 2 Libssh2, Redhat | 2 Libssh2, Hummingbird | 2026-07-28 | 7.5 High |
| libssh2 through 1.11.1, fixed in commit a2ed82d, contains a pre-authentication integer underflow vulnerability in the ssh2_cipher_crypt() function in src/openssl.c that allows a malicious SSH server to crash any connecting client by negotiating AES-GCM ciphers during handshake. Attackers can exploit the underflow in the expression computing blocksize minus aadlen minus authentication tag length to trigger an out-of-bounds read and a memcpy call with a near-SIZE_MAX length argument, causing immediate process crash before any authentication occurs. | ||||
| CVE-2026-63895 | 1 Linux | 1 Linux Kernel | 2026-07-27 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_fs: copy only received bytes on short ep0 read ffs_ep0_read() allocates its control-OUT data buffer with kmalloc() (not kzalloc) at the Length value from the Setup packet, then copies that full len to userspace regardless of how many bytes were actually received: data = kmalloc(len, GFP_KERNEL); ... ret = __ffs_ep0_queue_wait(ffs, data, len); if ((ret > 0) && (copy_to_user(buf, data, len))) ret = -EFAULT; __ffs_ep0_queue_wait() returns req->actual, which on a short control OUT transfer is strictly less than len. The copy_to_user() call still copies len bytes, so on a short OUT the last (len - ret) bytes of the kmalloc() buffer -- uninitialised slab residue -- are delivered to the FunctionFS daemon. Short ep0 OUT completions are specified USB control-transfer behavior and are produced by in-tree UDCs: * dwc2 continues on req->actual < req->length for ep0 DATA OUT (short-not-ok is the only ep0-OUT stall path). * aspeed_udc ends ep0 OUT on rx_len < ep->ep.maxpacket. * renesas_usbf logs "ep0 short packet" and completes the request. * dwc3 stalls on short IN but not on short OUT. A short ep0 OUT is therefore not evidence of a broken UDC; it is a normal condition f_fs has to cope with. The sibling gadgetfs implementation in drivers/usb/gadget/legacy/inode.c already does this correctly via min(len, dev->req->actual) before copy_to_user(). This patch brings f_fs.c to the same safe pattern rather than trimming at a defensive layer. The bug is reached from the FunctionFS device node, which in real deployments is owned by the privileged gadget daemon (adbd, UMS, composite gadget services, etc.); it is not reachable from unprivileged userspace. Linux host stacks normally reject short-wLength control OUTs before they reach the gadget, so reproducing this required a build that bypasses that host-side check. With the bypass in place, a 1-byte payload on a 64-byte Setup produces 63 bytes of non-canary slab residue in the daemon's read buffer. Fix by copying only ret (actually received) bytes to userspace. | ||||
| CVE-2026-32665 | 2 Nlnetlabs, Redhat | 2 Unbound, Hummingbird | 2026-07-27 | 7.5 High |
| In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, when downstream DNS-over-QUIC (DoQ) is enabled, the first two bidirectional streams on a new QUIC connection (stream_id 0 and 4) bypass the per-stream 'quic-size' gate entirely, and large input buffers are allocated later, after only the 2-byte length prefix has been received from the initial streams. As a result, a remote client can make Unbound exceed the configured 'quic-size' limit with low-cost input. Using only one connection and two streams, each sending a declared 65535-byte length prefix and then holding the streams open, a client can already trivially make Unbound roughly allocate double that amount. This is a remote availability issue / memory-accounting bypass in the downstream DoQ implementation that leads to denial of service for new DoQ clients. This vulnerability needs Unbound to be compiled with DoQ support ('--with-libngtcp2') and the 'quic-port' to be configured for the listening interfaces. | ||||
| CVE-2026-40691 | 2 Nlnetlabs, Redhat | 2 Unbound, Hummingbird | 2026-07-27 | 7.5 High |
| In Unbound 1.9.0 up to and including 1.25.1, when a DNSCrypt query is received over TCP, the routine that encrypts the reply in place fails to bound the reply length against the destination buffer size. The size clamp that protects the UDP path is not applied on the TCP path, so a reply larger than 65504 bytes is shifted forward by 48 bytes inside a buffer of capacity equal to 'msg-buffer-size', writing past the end of the heap allocation. A single malicious encrypted query crashes the resolver and lead to denial of service. This vulnerability needs Unbound to be compiled with DNSCrypt support ('--enable-dnscrypt') and the 'dnscrypt:' clause to be configured and enabled for the listening interfaces. | ||||
| CVE-2026-53566 | 1 Citrix | 1 Secure Access Client | 2026-07-27 | N/A |
| Out-of-bounds read vulnerability in Citrix Citrix Secure Access Client for Windows. This issue affects Citrix Secure Access Client for Windows: before 26.6.1.20. | ||||
