Summary
Evolver: Prototype Pollution via Object.assign() in mailbox store operations
Original description
The description as published by the source.
Evolver is a GEP-powered self-evolving engine for AI agents. Prior to version 1.69.3, a prototype pollution vulnerability in the mailbox store module allows attackers to modify the behavior of all JavaScript objects by injecting malicious properties into Object.prototype. The vulnerability exists in the _applyUpdate() and _updateRecord() functions which use Object.assign() to merge user-controlled data without filtering dangerous keys like proto, constructor, or prototype. This issue has been patched in version 1.69.3.
