AC:H because exploitation requires a specific vulnerable application code pattern (AT:P equivalent); PR:L for authenticated user; I:H and A:H reflect arbitrary rename and full-bucket chunk deletion respectively.

Lifecycle Timeline
3DescriptionCVE.org
Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Java 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 Java Driver allows an authenticated low-privilege user who can influence the file identifier passed by an affected application to break out of the intended document scope. By supplying a structured identifier containing MongoDB query operators instead of a literal file ID, the attacker can read file chunks belonging to other owners, delete all file chunks in the affected GridFS bucket (rendering stored content permanently unreadable), or rename an arbitrary stored file rather than the intended target. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Three conditions must simultaneously be true for exploitation: (1) the target application uses the MongoDB Java Driver's GridFS client API for file storage operations (find, rename, or delete); (2) the application accepts externally-supplied input (e.g., from an authenticated HTTP request) and passes that input as the file identifier argument to a GridFS operation without first validating it as a plain ObjectId literal; and (3) the attacker holds at least low-privilege authenticated access to the application (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.1 (Medium) with vector AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:H/VA:H reflects a nuanced picture: while integrity and availability impacts on the vulnerable system are rated High (file deletion and arbitrary rename), the AT:P (attack requirements present) metric acknowledges that exploitation is conditional on a specific application code pattern. … 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 | Upgrade to the fixed version of the MongoDB Java Driver once it is tagged and published following resolution of JIRA-6283 (https://jira.mongodb.org/browse/JAVA-6283); monitor that ticket and the MongoDB Maven artifact (org.mongodb:mongodb-driver-sync or legacy mongo-java-driver) for a patched release. … Detailed patch versions, workarounds, and compensating controls in full report. |
