GHSA-vc77-c2hx-h5x2: Mattermost Confluence Plugin has Improper Check for Unusual or Exceptional Conditions
Mattermost Confluence Plugin versions < 1.5.0 fails to handle unexpected request bodies, allowing attackers to crash the plugin via constant hits to the update channel subscription endpoint with an invalid request body.
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
