Improper Neutralization Vulnerability in MongoDB Python Driver

CVE-2026-88029

What is CVE-2026-88029?

The MongoDB Python Driver's GridFS component is susceptible to an improper neutralization flaw. This vulnerability occurs when a structured file identifier, supplied by an authenticated user, is improperly handled. Instead of being treated as a literal identifier, it can be misinterpreted as a query condition. This mismanagement enables potential data breaches, allowing unauthorized access to stored files or even the deletion of entire GridFS file chunks within the affected bucket. Additionally, a vulnerable rename operation could mistakenly alter a file that the user did not intend to change.
