| CVE-2026-1005 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 5.3 Medium |
| Integer underflow in wolfSSL packet sniffer <= 5.8.4 allows an attacker to cause a buffer overflow in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by ssl_DecodePacket. The underflow wraps a 16-bit length to a large value that is passed to AEAD decryption routines, causing heap buffer overflow and a crash. An unauthenticated attacker can trigger this remotely via malformed TLS Application Data records. | ||||
| CVE-2026-2646 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 8.1 High |
| A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSL_d2i_SSL_SESSION() function. When deserializing session data with SESSION_CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and corrupt heap memory. A maliciously crafted session would need to be loaded from an external source to trigger this vulnerability. Internal sessions were not vulnerable. | ||||
| CVE-2026-3548 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 9.8 Critical |
| Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs, either of these out of bound writes could be triggered. Note this only affects builds that specifically enable CRL support, and the user would need to load a CRL from an untrusted source. | ||||
| CVE-2026-4159 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 3.3 Low |
| 1-byte OOB heap read in wc_PKCS7_DecodeEnvelopedData via zero-length encrypted content. A vulnerability existed in wolfSSL 5.8.4 and earlier, where a 1-byte out-of-bounds heap read in wc_PKCS7_DecodeEnvelopedData could be triggered by a crafted CMS EnvelopedData message with zero-length encrypted content. Note that PKCS7 support is disabled by default. | ||||
| CVE-2026-5447 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 7.5 High |
| Heap buffer overflow in CertFromX509 via AuthorityKeyIdentifier size confusion. A heap buffer overflow occurs when converting an X.509 certificate internally due to incorrect size handling of the AuthorityKeyIdentifier extension. | ||||
| CVE-2026-5264 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 9.8 Critical |
| Heap buffer overflow in DTLS 1.3 ACK message processing. A remote attacker can send a crafted DTLS 1.3 ACK message that triggers a heap buffer overflow. | ||||
| CVE-2026-41384 | 1 Openclaw | 1 Openclaw | 2026-04-29 | 7.8 High |
| OpenClaw before 2026.3.24 contains an environment variable injection vulnerability in the CLI backend runner that allows attackers to inject malicious environment variables through workspace configuration. Attackers can craft malicious workspace configs to inject arbitrary environment variables into the backend process spawning, enabling code execution or sensitive data exposure. | ||||
| CVE-2026-41391 | 1 Openclaw | 1 Openclaw | 2026-04-29 | 5.3 Medium |
| OpenClaw before 2026.3.31 fails to properly sanitize PIP_INDEX_URL and UV_INDEX_URL environment variables in host execution contexts, allowing attackers to redirect Python package-index traffic. Attackers can exploit this bypass to intercept or manipulate package management operations by injecting malicious index URLs through unsanitized environment variables. | ||||
| CVE-2026-5772 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 5.3 Medium |
| A 1-byte stack buffer over-read was identified in the MatchDomainName function (src/internal.c) during wildcard hostname validation when the LEFT_MOST_WILDCARD_ONLY flag is active. If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash. | ||||
| CVE-2026-5778 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 6.5 Medium |
| Integer underflow in wolfSSL packet sniffer <= 5.9.0 allows an attacker to cause a program crash in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by ssl_DecodePacket. The underflow wraps a 16-bit length to a large value that is passed to AEAD decryption routines, causing a large out-of-bounds read and crash. An unauthenticated attacker can trigger this remotely via malformed TLS Application Data records. | ||||
| CVE-2026-5295 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 8.0 High |
| A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wc_PKCS7_DecryptOri() function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo (ORI) recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer (oriOID[MAX_OID_SZ]) via XMEMCPY without first validating that the parsed OID length does not exceed MAX_OID_SZ. A crafted CMS EnvelopedData message with an ORI recipient containing an OID longer than 32 bytes triggers a stack buffer overflow. Exploitation requires the library to be built with --enable-pkcs7 (disabled by default) and the application to have registered an ORI decrypt callback via wc_PKCS7_SetOriDecryptCb(). | ||||
| CVE-2026-41361 | 1 Openclaw | 1 Openclaw | 2026-04-29 | 7.1 High |
| OpenClaw before 2026.3.28 contains an SSRF guard bypass vulnerability that fails to block four IPv6 special-use ranges. Attackers can exploit this by crafting URLs targeting internal or non-routable IPv6 addresses to bypass SSRF protections. | ||||
| CVE-2026-5392 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 5.4 Medium |
| Heap out-of-bounds read in PKCS7 parsing. A crafted PKCS7 message can trigger an OOB read on the heap. The missing bounds check is in the indefinite-length end-of-content verification loop in PKCS7_VerifySignedData(). | ||||
| CVE-2026-5393 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 9.1 Critical |
| Dual-Algorithm CertificateVerify out-of-bounds read. When processing a dual-algorithm CertificateVerify message, an out-of-bounds read can occur on crafted input. This can only occur when --enable-experimental and --enable-dual-alg-certs is used when building wolfSSL. | ||||
| CVE-2026-5448 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 4.3 Medium |
| X.509 date buffer overflow in wolfSSL_X509_notAfter / wolfSSL_X509_notBefore. A buffer overflow may occur when parsing date fields from a crafted X.509 certificate via the compatibility layer API. This is only triggered when calling these two APIs directly from an application, and does not affect TLS or certificate verify operations in wolfSSL. | ||||
| CVE-2026-5188 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 8.1 High |
| An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name (SAN) extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect handling of certificate data. The issue is limited to configurations using the original ASN.1 parsing implementation which is off by default. | ||||
| CVE-2026-41915 | 1 Openclaw | 1 Openclaw | 2026-04-29 | 5.3 Medium |
| OpenClaw before 2026.4.8 fails to remove git plumbing environment variables from the execution environment before host exec operations. Attackers can exploit this by setting GIT_DIR and related variables to redirect git operations and compromise repository integrity. | ||||
| CVE-2026-32497 | 2 Pickplugins, Wordpress | 2 User Verification, Wordpress | 2026-04-29 | 5.3 Medium |
| Weak Authentication vulnerability in PickPlugins User Verification user-verification allows Authentication Abuse.This issue affects User Verification: from n/a through <= 2.0.45. | ||||
| CVE-2023-25983 | 2 Kbsupport, Logon | 2 Kb Support, Kb Support | 2026-04-29 | 8.8 High |
| Improper Neutralization of Formula Elements in a CSV File vulnerability in WPOmnia KB Support.This issue affects KB Support: from n/a through 1.5.84. | ||||
