CVE-2026-112934

filelock is a platform-independent file lock for Python. From 4.0.0 until 4.2.1, SoftReadWriteLock refreshes holder records by name, allowing another local user with rename access to the lock directory to replace a record with a named pipe and stall the lock, or under a permissive hard-link polic...

CVE-2026-112915 filelock ReadWriteLock: a crafted lock database makes every acquire stall or hang regardless of timeout

filelock is a platform-independent file lock for Python. From 3.20.4 until 4.2.1, ReadWriteLock can open a crafted SQLite lock database without bounding schema and query work, allowing another local user who can replace the database to make acquisition stall or hang; versions from 3.20.4 expose...

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...

CVE-2026-112914

The filelock Python library (versions 4.1.0 through 4.2.0 ) is vulnerable to a race condition (CWE-363) in its SoftFileLock component. An attacker with local rename access in a non-sticky lock directory can swap in a symbolic link . If the runtime follows the link to a same-filesystem target, it ...

CVE-2026-112914 filelock: SoftFileLock stale-break restore follows a swapped-in symbolic link and hard-links a file of the user running the lock into the lock directory

filelock is a platform-independent file lock for Python. From 4.1.0 until 4.2.1, SoftFileLock can restore a stale marker by name after moving it aside, allowing another local user with rename access in a non-sticky lock directory to swap in a symbolic link and, on a runtime that follows the link...

CVE-2026-112912 filelock: Symlink swap during SoftFileLock's writability check leaks whether a path exists and is writable by the lock taker

filelock is a platform-independent file lock for Python. From 3.32.6 until 4.2.1, SoftFileLock can follow a swapped symbolic link during the conditional os.access writability check for a node without its owner-write bit, allowing another local user on a platform and directory configuration that...
