CVE-2022-25862Public exploit

Prototype pollution via constructor.prototype key paths

Published May 13, 2022 · Updated Sep 16, 2024

Prototype pollution in monsterkodi SDS 0.0.0 and later allows attackers to modify Object.prototype via a crafted key path. The set function in js/set.js rejects proto but traverses constructor.prototype and assigns the supplied value to the shared prototype. Reachability depends on a caller passing attacker-controlled paths to set; polluted properties then affect other objects in that Node.js process.
