CVE-2026-88023: CWE-943: Improper Neutralization of Special Elements in Data Query Logic in MongoDB MongoDB PHP Library
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB PHP Library can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable. The affected rename operation may also rename a stored file other than the intended target.
AI Analysis
Technical Summary
This vulnerability arises from improper neutralization of special elements in data query logic within the GridFS component of the MongoDB PHP Library. Specifically, a caller-supplied structured file identifier can be interpreted as a query condition rather than a literal identifier. An authenticated user who can influence the identifier passed by an affected application may retrieve stored file content beyond the intended target, delete all GridFS file chunks in the affected bucket, or cause the rename operation to affect a different stored file than intended. The affected versions are MongoDB PHP Library versions >=1.1.0 <=1.21.4 and >=2.0.0 <=2.4.1.
Potential Impact
An authenticated user with the ability to influence file identifiers can access unauthorized file content, delete all file chunks in a GridFS bucket making stored content unreadable, or rename files other than the intended target. This can lead to data exposure, data loss, and potential disruption of application functionality relying on GridFS storage.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, applications should carefully validate and sanitize user-supplied file identifiers used in GridFS operations to prevent interpretation as query conditions.
