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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":36,"depthScoreParts":{"impact":23.7,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":209804,"id":"CVE-2026-61834","ts":1790184549548,"field":"exploit_available","old":"false","new":"true"}]}
