CVE-2026-112909 (GCVE-0-2026-112909)

Vulnerability from cvelistv5 – Published: 2026-10-20 14:16 – Updated: 2026-10-22 21:25

Title

filelock: UnixFileLock truncates and chmods any regular file another user renames or hard-links onto the lock path

Summary

filelock is a platform-independent file lock for Python. Prior to 4.2.1, UnixFileLock can truncate a regular file renamed onto the lock path when another local user has actual rename permission, or hard-linked there under a permissive hard-link policy; when an explicit mode is requested, affected versions from 3.10.2 can also change that file's mode. This issue is fixed in version 4.2.1.

Severity

6.1 (Medium)

CVE-2026-112935 (GCVE-0-2026-112935)

Vulnerability from cvelistv5 – Published: 2026-10-20 14:32 – Updated: 2026-10-28 14:17

Title

filelock: SoftFileLock stale-lock break removes a live lock file on a reused inode number and admits two holders

Summary

filelock is a platform-independent file lock for Python. From 3.22.0 until 4.2.1, SoftFileLock can break a stale marker after an attacker frees its own marker following the stale read, an honest contender creates a live successor on the reused inode, and the successor's modification time is not newer than the saved observation, causing the live marker to be removed and two holders to be admitted. This issue is fixed in version 4.2.1.

Severity

4.7 (Medium)

Title

filelock: SoftFileLock removes a live holder's marker when another user forges the PID in a writable marker

Summary

filelock is a platform-independent file lock for Python. From 3.22.0 until 4.2.1, SoftFileLock can trust a forged process identifier in a marker that an attacker can modify but cannot remove, allowing an authorized contender such as another process of the holder's account or root to act as a confused deputy, remove the live marker, and admit another holder. This issue is fixed in version 4.2.1.

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.
Browse all ATT&CK techniques and the vulnerabilities related to each.
