CVE-2024-53900

Mongoose versions prior to 8.8.3, 7.8.3, and 6.13.5 are vulnerable to improper use of the $where operator. This vulnerability arises from the ability of the $where clause to execute arbitrary JavaScript code in MongoDB queries, potentially leading to code injection attacks and unauthorized access or manipulation of database data.

CVE-2025-23061

Mongoose versions prior to 8.9.5, 7.8.4, and 6.13.6 are vulnerable to improper use of the $where operator. This vulnerability arises from the ability of the $where clause to execute arbitrary JavaScript code in MongoDB queries, potentially leading to code injection attacks and unauthorized access or manipulation of database data.

NOTE: this issue exists because of an incomplete fix for CVE-2024-53900.
