CVE-2025-24362githubcodeql-action1y ago24-01-2025 18:04

In some circumstances, debug artifacts uploaded by the CodeQL Action after a failed code scanning workflow run may contain the environment variables from the workflow run, including any secrets that were exposed as environment variables to the workflow. Users with read access to the repository would be able to access this artifact, containing any secrets from the environment. This vulnerability is patched in CodeQL Action version 3.28.3 or later, or CodeQL CLI version 2.20.3 or later. For some affected workflow runs, the exposed environment variables in the debug artifacts included a valid `GITHUB_TOKEN` for the workflow run, which has access to the repository in which the workflow ran, and all the permissions specified in the workflow or job. The `GITHUB_TOKEN` is valid until the job completes or 24 hours has elapsed, whichever comes first. Environment variables are exposed only from workflow runs that satisfy all of the following conditions: - Code scanning workflow configured to scan the Java/Kotlin languages. - Running in a repository containing Kotlin source code. - Running with debug artifacts enabled. - Using CodeQL Action versions <= 3.28.2, and CodeQL CLI versions >= 2.9.2 (May 2022) and <= 2.20.2. - The workflow run fails before the CodeQL database is finalized within the `github/codeql-action/analyze` step. - Running in any GitHub environment: GitHub.com, GitHub Enterprise Cloud, and GitHub Enterprise Server. Note: artifacts are only accessible to users within the same GitHub environment with access to the scanned repo. The `GITHUB_TOKEN` exposed in this way would only have been valid for workflow runs that satisfy all of the following conditions, in addition to the conditions above: - Using CodeQL Action versions >= 3.26.11 (October 2024) and <= 3.28.2, or >= 2.26.11 and < 3. - Running in GitHub.com or GitHub Enterprise Cloud only (not valid on GitHub Enterprise Server). In rare cases during advanced setup, logging of environment variables may also occur during database creation of Java, Swift, and C/C++. Please read the corresponding CodeQL CLI advisory GHSA-gqh3-9prg-j95m for more details. In CodeQL CLI versions >= 2.9.2 and <= 2.20.2, the CodeQL Kotlin extractor logs all environment variables by default into an intermediate file during the process of creating a CodeQL database for Kotlin code. This is a part of the CodeQL CLI and is invoked by the CodeQL Action for analyzing Kotlin repositories. On Actions, the environment variables logged include GITHUB_TOKEN, which grants permissions to the repository being scanned. The intermediate file containing environment variables is deleted when finalizing the database, so it is not included in a successfully created database. It is, however, included in the debug artifact that is uploaded on a failed analysis run if the CodeQL Action was invoked in debug mode. Therefore, under these specific circumstances (incomplete database creation using the CodeQL Action in debug mode) an attacker with access to the debug artifact would gain unauthorized access to repository secrets from the environment, including both the `GITHUB_TOKEN` and any user-configured secrets made available via environment variables. The impact of the `GITHUB_TOKEN` leaked in this environment is limited: - For workflows on GitHub.com and GitHub Enterprise Cloud using CodeQL Action versions >= 3.26.11 and <= 3.28.2, or >= 2.26.11 and < 3, which in turn use the `actions/artifacts v4` library, the debug artifact is uploaded before the workflow job completes. During this time the `GITHUB_TOKEN` is still valid, providing an opportunity for attackers to gain access to the repository. - For all other workflows, the debug artifact is uploaded after the workflow job completes, at which point the leaked `GITHUB_TOKEN` has been revoked and cannot be used to access the repository.CVE-2025-6600githubenterprise_server+11y ago01-07-2025 18:56

An exposure of sensitive information vulnerability was identified in GitHub Enterprise Server that could allow an attacker to disclose the names of private repositories within an organization.

This vulnerability was reported via the GitHub Bug Bounty program.CVE-2025-3509githubenterprise_server1y ago17-04-2025 22:50

A Remote Code Execution (RCE) vulnerability was identified in GitHub Enterprise Server that allowed attackers to execute arbitrary code by exploiting the pre-receive hook functionality, potentially leading to privilege escalation and system compromise. The vulnerability involves using dynamically allocated ports that become temporarily available, such as during a hot patch upgrade. This means the vulnerability is only exploitable during specific operational conditions, which limits the attack window. Exploitation required either site administrator permissions to enable and configure pre-receive hooks or a user with permissions to modify repositories containing pre-receive hooks where this functionality was already enabled. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.18 and was fixed in versions 3.17.1, 3.16.4, 3.15.8, 3.14.13, 3.13.16.

The am function in lib/hub/commands.rb in hub before 1.12.1 allows local users to overwrite arbitrary files via a symlink attack on a temporary patch file.CVE-2022-21687githubgh-ost+14y ago01-02-2022 11:56

gh-ost is a triggerless online schema migration solution for MySQL. Versions prior to 1.1.3 are subject to an arbitrary file read vulnerability. The attacker must have access to the target host or trick an administrator into executing a malicious gh-ost command on a host running gh-ost, plus network access from host running gh-ost to the attack's malicious MySQL server. The `-database` parameter does not properly sanitize user input which can lead to arbitrary file reads.CVE-2022-31026RubyGemstrilogy+24y ago06-06-2022 21:05

Trilogy is a client library for MySQL. When authenticating, a malicious server could return a specially crafted authentication packet, causing the client to read and return up to 12 bytes of data from an uninitialized variable in stack memory. Users of the trilogy gem should upgrade to version 2.1.1 This issue can be avoided by only connecting to trusted servers.CVE-2022-39209debiancmark-gfm+74y ago15-09-2022 00:00

cmark-gfm is GitHub's fork of cmark, a CommonMark parsing and rendering library and program in C. In versions prior to 0.29.0.gfm.6 a polynomial time complexity issue in cmark-gfm's autolink extension may lead to unbounded resource exhaustion and subsequent denial of service. Users may verify the patch by running `python3 -c 'print("![l"* 100000 + "\n")' | ./cmark-gfm -e autolink`, which will resource exhaust on unpatched cmark-gfm but render correctly on patched cmark-gfm. This vulnerability has been patched in 0.29.0.gfm.6. Users are advised to upgrade. Users unable to upgrade should disable the use of the autolink extension.CVE-2022-39321actionsrunner+13y ago25-10-2022 00:00

GitHub Actions Runner is the application that runs a job from a GitHub Actions workflow. The actions runner invokes the docker cli directly in order to run job containers, service containers, or container actions. A bug in the logic for how the environment is encoded into these docker commands was discovered in versions prior to 2.296.2, 2.293.1, 2.289.4, 2.285.2, and 2.283.4 that allows an input to escape the environment variable and modify that docker command invocation directly. Jobs that use container actions, job containers, or service containers alongside untrusted user inputs in environment variables may be vulnerable. The Actions Runner has been patched, both on `github.com` and hotfixes for GHES and GHAE customers in versions 2.296.2, 2.293.1, 2.289.4, 2.285.2, and 2.283.4. GHES and GHAE customers may want to patch their instance in order to have their runners automatically upgrade to these new runner versions. As a workaround, users may consider removing any container actions, job containers, or service containers from their jobs until they are able to upgrade their runner versions.CVE-2022-46255githubenterprise_server+13y ago14-12-2022 00:00
