Summary
python-filelock vulnerabilities
Details

It was discovered that Filelock incorrectly handled symlinks in temp files. A local attacker could possibly use this issue to cause lock operations to fail or behave unexpectedly. (CVE-2026-22701)

It was discovered that the file locking implementation in the Filelock package contained a race condition. A local attacker could possibly use this to cause a denial of service or corrupt arbitrary user files. (CVE-2025-68146)
