Name of the Vulnerable Software and Affected Versions
Mattermost versions 8.1.x through 8.1.12
Mattermost versions 9.5.x through 9.5.3
Mattermost versions 9.6.x through 9.6.1
Description
The issue is related to improper access control, allowing a guest to obtain metadata of a public playbook run linked to the channel they are a guest in. This is achieved by sending an RHSRuns GraphQL query request to the server.
Recommendations
For Mattermost versions 8.1.x through 8.1.12, update to a version that includes the fix for this issue.
For Mattermost versions 9.5.x through 9.5.3, update to a version that includes the fix for this issue.
For Mattermost versions 9.6.x through 9.6.1, update to a version that includes the fix for this issue.
As a temporary workaround, consider restricting access to the RHSRuns GraphQL query endpoint to minimize the risk of exploitation.
