CVE-2025-65570 - Jsish Type Confusion Vulnerability Allows Code Execution

CVE ID : CVE-2025-65570 Published : Dec. 29, 2025, 3:16 p.m. | 48 minutes ago Description : A type confusion in jsish 2.0 allows incorrect control flow during execution of the OP_NEXT opcode. When an “instanceof” 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.
