CVE-2025-68279
📋 TL;DR
This vulnerability in Weblate allows attackers to read arbitrary files from the server file system by exploiting crafted symbolic links in repositories. It affects all Weblate installations prior to version 5.15.1. Attackers could potentially access sensitive configuration files, credentials, or other system data.
💻 Affected Systems
- Weblate
📦 What is this software?
Weblate by Weblate
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise through reading sensitive files like SSH keys, database credentials, or configuration secrets leading to lateral movement or data exfiltration.
Likely Case
Unauthorized access to sensitive files containing API keys, passwords, or proprietary data stored on the server.
If Mitigated
Limited file access restricted by file permissions and proper repository isolation, potentially only accessing non-sensitive files.
🎯 Exploit Status
Exploitation requires ability to create or modify repository content with symbolic links, typically requiring some level of access to the Weblate instance.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.15.1

🔧 Temporary Workarounds
Restrict repository access
allLimit who can create or modify repositories to trusted users only
File system permissions hardening
linuxSet strict file permissions on sensitive directories and files outside the repository scope
chmod 600 /etc/weblate/settings.py
chmod 700 /var/lib/weblate
🧯 If You Can't Patch
- Implement strict access controls on repository creation and modification
- Monitor for suspicious file access patterns and audit repository content regularly
🔍 How to Verify
Check if Vulnerable:
Check Weblate version via admin interface or command: weblate --versionCheck Version:
