2DescriptionCVE.org
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB C
Driver 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.
AnalysisAI
NoSQL injection in the GridFS component of the MongoDB C# Driver allows an authenticated low-privilege attacker who can influence file identifiers passed by an affected application to execute query-condition attacks against GridFS bucket operations. Exploitation can yield unauthorized read access to stored file content, complete destruction of all file chunks in the affected bucket (rendering all stored content unrecoverable), or misdirection of rename operations to unintended files. …

Vulnerability AssessmentAI
| Exploitation | The attacker must be authenticated to the application with at least low-level privileges (PR:L per CVSS 4.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.1 with vector AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:H/VA:H is well-calibrated. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation reference is MongoDB JIRA CSHARP-6190 (https://jira.mongodb.org/browse/CSHARP-6190); a confirmed fixed version of the MongoDB C# Driver is not available from the data provided. … Detailed patch versions, workarounds, and compensating controls in full report. |
