When an \u201cinstanceof\u201d expression uses an array element access as the left-hand operand inside a for-in loop, the instructions implementation leaves an additional array reference on the stack rather than consuming it during OP_INSTANCEOF. As a result, OP_NEXT interprets the array as an iterator object and reads the iterCmd function pointer from an invalid structure, potentially causing a crash or enabling code execution depending on heap layout."}], "lastModified": "2025-12-31T20:04:10.750", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:jsish:jsish:2.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D2EBBCFD-094B-4ABF-B39E-A3EBD0D2CC83"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
