NVD Description

Note: Versions mentioned in the description apply only to the upstream python-filelock package and not the python-filelock package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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 follows the link to infer whether a chosen path exists and is writable from the observable acquisition result. This issue is fixed in version 4.2.1.
