02 Description

MISP: Insufficient Authorization Allows Sharing Group Editors to Overwrite Organization Metadata

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.38% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 31.8% of scored records. A rank, not a probability.
NVD base score
5.3 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

The fix adds an authorization check to the captureOrg method so that the forced overwrite of organization metadata fields is only permitted when the invoking user holds either the site_admin permission or the sync permission. This ensures that low-privilege roles such as sharing group editors can no longer trigger the metadata overwrite path, closing the authorization gap.
