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 and a same-filesystem target, make the lock user hard-link one of its files into the lock directory. This issue is fixed in version 4.2.1.","state":0,"publishedAt":"2026-10-20T14:26:18.813+00:00","modifiedAt":"2026-10-21T15:55:21.992+00:00","affected":[{"ecosystem":"Vendor product","name":"filelock","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tox-dev\",\n                    \"product\": \"filelock\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.1.0, < 4.2.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/tox-dev/filelock/security/advisories/GHSA-crv4-6mhj-j5jh","https://github.com/tox-dev/filelock/pull/843","https://github.com/tox-dev/filelock/commit/740ff666b62a88496c8d7394e4e6230605e4d62b","https://github.com/tox-dev/filelock/releases/tag/4.2.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112914","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112914","identifiers":["CVE-2026-112914"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
