Prior to 0.9.2, navigate() reads inherited properties and assign() uses prototype-chain membership checks while resolving attacker-controlled SCIM PATCH paths. A path or one of the dotted value keys beginning with an inherited property such as toString can therefore traverse into a shared built-in function object and add attacker-controlled properties, causing process-global mutation that may affect application logic reading inherited-method properties. This issue is fixed in version 0.9.2.","state":0,"publishedAt":"2026-09-23T14:02:01.131+00:00","modifiedAt":"2026-09-23T16:20:22.098+00:00","affected":[{"ecosystem":"Vendor product","name":"scim-patch","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"thomaspoignant\",\n                    \"product\": \"scim-patch\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.9.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/thomaspoignant/scim-patch/security/advisories/GHSA-2mhw-wcx5-v3xj","https://github.com/thomaspoignant/scim-patch/pull/1127","https://github.com/thomaspoignant/scim-patch/commit/c86474f7a9b16191d939f59ba94eca6c6e63044b","https://github.com/thomaspoignant/scim-patch/releases/tag/v0.9.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-61834","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-61834","identifiers":["CVE-2026-61834"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
