CVE-2026-3854 1 Github 1 Enterprise Server 2026-04-18 8.8 High
An improper neutralization of special elements vulnerability was identified in GitHub Enterprise Server that allowed an attacker with push access to a repository to achieve remote code execution on the instance. During a git push operation, user-supplied push option values were not properly sanitized before being included in internal service headers. Because the internal header format used a delimiter character that could also appear in user input, an attacker could inject additional metadata fields through crafted push option values. This vulnerability was reported via the GitHub Bug Bounty program and has been fixed in GitHub Enterprise Server versions 3.14.25, 3.15.20, 3.16.16, 3.17.13, 3.18.7 and 3.19.4.
CVE-2026-21434 1 Quic-go 1 Webtransport-go 2026-04-18 5.3 Medium
webtransport-go is an implementation of the WebTransport protocol. From 0.3.0 to 0.9.0, an attacker can cause excessive memory consumption in webtransport-go's session implementation by sending a WT_CLOSE_SESSION capsule containing an excessively large Application Error Message. The implementation does not enforce the draft-mandated limit of 1024 bytes on this field, allowing a peer to send an arbitrarily large message payload that is fully read and stored in memory. This allows an attacker to consume an arbitrary amount of memory. The attacker must transmit the full payload to achieve the memory consumption, but the lack of any upper bound makes large-scale attacks feasible given sufficient bandwidth. This vulnerability is fixed in 0.10.0.
CVE-2026-25598 2 Step Security, Stepsecurity 2 Harden Runner, Harden-runner 2026-04-18 5.3 Medium
Harden-Runner is a CI/CD security agent that works like an EDR for GitHub Actions runners. Prior to 2.14.2, a security vulnerability has been identified in the Harden-Runner GitHub Action (Community Tier) that allows outbound network connections to evade audit logging. Specifically, outbound traffic using the sendto, sendmsg, and sendmmsg socket system calls can bypass detection and logging when using egress-policy: audit. This vulnerability is fixed in 2.14.2.
CVE-2026-23689 1 Sap 2 Advanced Planning And Optimization, Supply Chain Management 2026-04-18 7.7 High
Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.
CVE-2026-1847 1 Mongodb 1 Mongodb 2026-04-18 6.5 Medium
Inserting certain large documents into a replica set could lead to replica set secondaries not being able to fetch the oplog from the primary. This could stall replication inside the replica set leading to server crash.
CVE-2026-1456 1 Gitlab 1 Gitlab 2026-04-18 6.5 Medium
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.7 before 18.7.4, and 18.8 before 18.8.4 that could have allowed an unauthenticated user to cause denial of service through CPU exhaustion by submitting specially crafted markdown files that trigger exponential processing in markdown preview.
CVE-2026-2823 1 Comfast 2 Cf-e7, Cf-e7 Firmware 2026-04-18 6.3 Medium
A vulnerability was detected in Comfast CF-E7 2.6.0.9. The impacted element is the function sub_41ACCC of the file /cgi-bin/mbox-config?method=SET&section=ntp_timezone of the component webmggnt. Performing a manipulation of the argument timestr results in command injection. The attack is possible to be carried out remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-22803 1 Svelte 1 Kit 2026-04-18 7.5 High
SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. From 2.49.0 to 2.49.4, the experimental form remote function uses a binary data format containing a representation of submitted form data. A specially-crafted payload can cause the server to allocate a large amount of memory, causing DoS via memory exhaustion. This vulnerability is fixed in 2.49.5.
CVE-2026-25579 1 Navidrome 1 Navidrome 2026-04-17 6.5 Medium
Navidrome is an open source web-based music collection server and streamer. Prior to version 0.60.0, authenticated users can crash the Navidrome server by supplying an excessively large size parameter to /rest/getCoverArt or to a shared-image URL (/share/img/<token>). When processing such requests, the server attempts to create an extremely large resized image, causing uncontrolled memory growth. This triggers the Linux OOM killer, terminates the Navidrome process, and results in a full service outage. If the system has sufficient memory and survives the allocation, Navidrome then writes these extremely large resized images into its cache directory, allowing an attacker to rapidly exhaust server disk space as well. This issue has been patched in version 0.60.0.
CVE-2026-35602 2 Go-vikunja, Vikunja 2 Vikunja, Vikunja 2026-04-17 5.4 Medium
Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the Vikunja file import endpoint uses the attacker-controlled Size field from the JSON metadata inside the import zip instead of the actual decompressed file content length for the file size enforcement check. By setting Size to 0 in the JSON while including large compressed file entries in the zip, an attacker bypasses the configured maximum file size limit. This vulnerability is fixed in 2.3.0.
CVE-2026-25761 2 Super-linter, Super-linter Project 2 Super-linter, Super-linter 2026-04-17 8.8 High
Super-linter is a combination of multiple linters to run as a GitHub Action or standalone. From 6.0.0 to 8.3.0, the Super-linter GitHub Action is vulnerable to command injection via crafted filenames. When this action is used in downstream GitHub Actions workflows, an attacker can submit a pull request that introduces a file whose name contains shell command substitution syntax, such as $(...). In affected Super-linter versions, runtime scripts may execute the embedded command during file discovery processing, enabling arbitrary command execution in the workflow runner context. This can be used to disclose the job’s GITHUB_TOKEN depending on how the workflow configures permissions. This vulnerability is fixed in 8.3.1.
CVE-2026-1848 1 Mongodb 1 Mongodb 2026-04-17 7.5 High
Connections received from the proxy port may not count towards total accepted connections, resulting in server crashes if the total number of connections exceeds available resources. This only applies to connections accepted from the proxy port, pending the proxy protocol header.
CVE-2026-24661 1 Mattermost 1 Mattermost 2026-04-17 3.7 Low
Mattermost Plugins versions <=2.1.3.0 fail to limit the request body size on the {{/changes}} webhook endpoint which allows an authenticated attacker to cause memory exhaustion and denial of service via sending an oversized JSON payload. Mattermost Advisory ID: MMSA-2026-00611
CVE-2026-1850 1 Mongodb 1 Mongodb 2026-04-17 6.5 Medium

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 8.0 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4 that, under certain conditions could have allowed an unauthenticated user to cause denial of service by uploading malicious files.
CVE-2026-1387 1 Gitlab 1 Gitlab 2026-04-17 6.5 Medium
GitLab has remediated an issue in GitLab EE affecting all versions from 15.6 before 18.6.6, 18.7 before 18.7.4, and 18.8 before 18.8.4 that could have allowed an authenticated user to cause Denial of Service by uploading a malicious file and repeatedly querying it through GraphQl.
CVE-2026-1837 2 Google, Libjxl Project 2 Libjxl, Libjxl 2026-04-17 7.5 High
A specially-crafted file can cause libjxl's decoder to write pixel data to uninitialized unallocated memory. Soon after that data from another uninitialized unallocated region is copied to pixel data. This can be done by requesting color transformation of grayscale images to another grayscale color space. Buffers allocated for 1-float-per-pixel are used as if they are allocated for 3-float-per-pixel. That happens only if LCMS2 is used as CMS engine. There is another CMS engine available (selected by build flags).
CVE-2026-25949 1 Traefik 1 Traefik 2026-04-17 7.5 High
Traefik is an HTTP reverse proxy and load balancer. Prior to 3.6.8, there is a potential vulnerability in Traefik managing STARTTLS requests. An unauthenticated client can bypass Traefik entrypoint respondingTimeouts.readTimeout by sending the 8-byte Postgres SSLRequest (STARTTLS) prelude and then stalling, causing connections to remain open indefinitely, leading to a denial of service. This vulnerability is fixed in 3.6.8.
CVE-2026-26076 2 Pendulum-project, Tweedegolf 2 Ntpd-rs, Ntpd-rs 2026-04-17 7.5 High
ntpd-rs is a full-featured implementation of the Network Time Protocol. Prior to 1.7.1, an attacker can remotely induce moderate increases (2-4 times above normal) in cpu usage. When having NTS enabled on an ntpd-rs server, an attacker can create malformed NTS packets that take significantly more effort for the server to respond to by requesting a large number of cookies. This can lead to degraded server performance even when a server could otherwise handle the load. This vulnerability is fixed in 1.7.1.
CVE-2026-26068 1 Jm33-m0 1 Emp3r0r 2026-04-17 9.9 Critical
emp3r0r is a stealth-focused C2 designed by Linux users for Linux environments. Prior to 3.21.1, untrusted agent metadata (Transport, Hostname) is accepted during check-in and later interpolated into tmux shell command strings executed via /bin/sh -c. This enables command injection and remote code execution on the operator host. This vulnerability is fixed in 3.21.1.
