CVE-2026-125118
Description
A flaw was found in Mongoose. When defining nested virtual paths in database schemas, the software fails to properly sanitize special object property names. A remote attacker who can influence schema field definitions—such as through dynamic form builders—can supply crafted property names to inject attributes into base JavaScript objects (prototype pollution). This unauthorized modification can allow an attacker to bypass authorization controls or disrupt application functionality.
