CVE-2026-61834: CWE-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes in thomaspoignant scim-patch
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.
AI Analysis
Technical Summary
The scim-patch library prior to version 0.9.2 contains a vulnerability where the navigate() function reads inherited properties and assign() uses prototype-chain membership checks when resolving SCIM PATCH paths controlled by an attacker. This allows traversal into shared built-in function objects and the addition of attacker-controlled properties, resulting in process-global mutations. Such mutations can impact application logic that reads inherited method properties. The vulnerability is addressed in version 0.9.2.
Potential Impact
This vulnerability can lead to unintended modifications of global built-in objects via prototype pollution, potentially altering application behavior that depends on inherited methods. There is no direct confidentiality or availability impact reported. The integrity of application logic may be affected due to process-global mutations.
Mitigation Recommendations
Upgrade scim-patch to version 0.9.2 or later, where this vulnerability is fixed. No other mitigation is indicated by the vendor advisory.
