CVE-2026-61834

4.3 mediumEPSS 0.4%

Medium (4.3). EPSS 0.4% chance of exploitation in the next 30 days. Fixed in scim-patch 0.9.2.

scim-patch is a library for applying SCIM patch operations. 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.
