Security readout for executives and security teams
Plain-English summary
MISP 2.4.127 could disclose metadata about threat-intelligence attributes a user should not be able to reach. The issue is limited to correlation metadata reported through the attribute restsearch API, not confirmed full attribute content access in the provided sources.
Executive priority
Prioritize this where MISP contains sensitive threat intelligence shared across trust boundaries. Treat it as a confidentiality and partner-trust risk, with urgency driven by API exposure and tenant/user separation needs.
Technical view
The vulnerable code path is app/Model/Attribute.php in MISP 2.4.127. When querying the attribute restsearch API, attribute correlation handling lacked an ACL lookup, allowing metadata about a correlating but otherwise unreachable attribute to be revealed.
Likely exposure
Exposure is most relevant to organizations running MISP 2.4.127 with users or integrations querying the attribute restsearch API, especially where attribute visibility and sharing boundaries matter.
Exploitation context
The source bundle does not cite active exploitation, and KEV is false. Evidence supports an information disclosure issue tied to missing ACL enforcement, but not public exploitation or unauthenticated access.
Researcher notes
Do not assume broader data disclosure than the CVE states. Focus review on correlation metadata returned by attribute restsearch and whether ACL checks are applied before exposing correlating attribute details.
Mitigation direction
- Identify any deployed MISP 2.4.127 instances.
- Review the linked MISP commit and vendor release guidance.
- Upgrade to a MISP release that includes the ACL fix, if available.
- Restrict API access to trusted users and integrations.
- Review sharing groups and attribute access controls.
Validation and detection
- Confirm the running MISP version on all environments.
- Check whether the linked fix is present in app/Model/Attribute.php.
- Review restsearch API usage by users and automation.
- Audit logs for unusual attribute restsearch queries.
- Verify lower-privileged users cannot see unreachable correlation metadata.
