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.
AnalysisAI
GridFS NoSQL injection in the MongoDB C Driver (libmongoc) enables authenticated users with influence over file identifier parameters to either access file content beyond their intended authorization or destroy all GridFS file chunks in the affected bucket, rendering stored data permanently unreadable. The root cause (CWE-943) is the driver's failure to distinguish between structured query operators and literal identifier values in GridFS operations, allowing attacker-controlled input to redirect or broaden MongoDB queries. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) the attacker holds at minimum a low-privilege authenticated session with the application (PR:L - unauthenticated access is not sufficient); (2) the application uses the MongoDB C Driver's GridFS component to store or retrieve files; and (3) the application passes user-supplied or user-influenced values as GridFS file identifiers to driver operations without first sanitizing them or strictly casting to a non-injectable type such as ObjectId. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.1 (Medium) with AT:P correctly reflects that exploitation depends on a specific application-level condition - the application must pass user-influenced values as GridFS identifiers without strict typing or sanitization - which limits the attack surface relative to a fully unauthenticated, condition-free vector. … 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 | Monitor and apply the patched MongoDB C Driver release once confirmed via the vendor's Jira tracker at https://jira.mongodb.org/browse/CDRIVER-6427, as a specific fixed version was not available in current references. … Detailed patch versions, workarounds, and compensating controls in full report. |
