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 policy to link a reachable target file and cause the lock user to write through it. This issue is fixed in version 4.2.1.","state":0,"publishedAt":"2026-10-20T14:30:43.736+00:00","modifiedAt":"2026-10-22T21:28:27.242+00:00","affected":[{"ecosystem":"Vendor product","name":"filelock","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"tox-dev\",\n                    \"product\": \"filelock\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.0.0, < 4.2.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/tox-dev/filelock/security/advisories/GHSA-fj95-fr6c-h845","https://github.com/tox-dev/filelock/pull/842","https://github.com/tox-dev/filelock/commit/bfa066d65a1ba9106f86ee9d027f7588b9c77e03","https://github.com/tox-dev/filelock/releases/tag/4.2.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-112934","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-112934","identifiers":["CVE-2026-112934"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
