Application interruption via unsafe recursive merge
Published Feb 5, 2025 · Updated Mar 13, 2025
Prototype pollution in xe-utils 3.7.1 and earlier allows remote attackers to interrupt applications through a crafted merge payload. The merge() recursion follows an inherited proto object and copies attacker-controlled properties onto Object.prototype. Exposure requires a consuming application to pass attacker-controlled objects into merge(); polluted inherited properties can trigger exceptions and interrupt that process.
