CVE-2026-112936 filelock: ReadWriteLock follows a symlink at the lock path into SQLite

filelock is a platform-independent file lock for Python. From 3.20.4 until 4.0.9, ReadWriteLock and AsyncReadWriteLock versions from 3.20.4 resolve the lock path and pass it to SQLite without rejecting a final symbolic link, allowing another local user who can create names in the lock directory t...

CVE-2026-112936

The filelock Python library (versions 3.20.4 through 4.0.9 ) contains a vulnerability where ReadWriteLock and AsyncReadWriteLock resolve lock paths and pass them to SQLite without rejecting a final symbolic link. This allows a local user with the ability to create names in the lock directory to r...

CVE-2026-112935

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...

CVE-2026-112915

The filelock Python library (versions 3.20.4 through 4.2.0 ) is vulnerable to a Denial of Service (DoS) via CWE-400 in its ReadWriteLock component. A local user capable of replacing the lock database can provide a crafted SQLite database that lacks bounded schema and query work limits. This cause...
