CVE-2025-4949
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisAn XML parser processes external entity references inside untrusted documents, letting an attacker read local files, reach internal systems, or exhaust resources. It's a common trap in anything that accepts XML. The fix is to disable external entities and DTD processing in the parser.

JGit 7.1.1.202505221757 (or latest 7.x stable release)
- 1. Identify the current JGit version in use by checking project dependencies or build configuration (e.g., pom.xml, build.gradle)
- 2. For JGit 5.x: upgrade to version 5.13.4 or later
- 3. For JGit 6.x: upgrade to version 6.10.1.202505221210 or later
- 4. For JGit 7.0.x: upgrade to version 7.0.1.202505221510 or later
- 5. For JGit 7.1.x: upgrade to version 7.1.1.202505221757 or later
- 6. Rebuild and test the application to ensure compatibility with the new version
- 7. Verify the fix by confirming the XXE vulnerability is no longer present in the updated JGit library
