Description

In Eclipse JGit versions 7.2.0.202503040940-r and older, the ManifestParser class used by the repo command and the AmazonS3 class used to implement the experimental amazons3 git transport protocol allowing to store git pack files in an Amazon S3 bucket, are vulnerable to XML External Entity (XXE) attacks when parsing XML files. This vulnerability can lead to information disclosure, denial of service, and other security issues.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.eclipse.jgit:org.eclipse.jgit, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.eclipse.jgit:org.eclipse.jgit to 7.2.1.202505142326-r or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-4949 is resolved across your whole dependency graph.

  3. Workarounds

    Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.

Red HatModerate

This vulnerability is rated Moderate for Red Hat products. A flaw in Eclipse JGit allows for XML External Entity (XXE) attacks when parsing specially crafted XML files. This can lead to local denial of service in affected Red Hat products that utilize JGit's ManifestParser or AmazonS3 class for git transport. The…
