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)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
