Summary

pH7Builder (pH7 Social Dating CMS) before 18.5.0 contains an improper authorization flaw in the note module delete() action, tracked under CWE-639. Authenticated members can delete other members' note comments and categories by submitting another member's note ID in the POST id parameter, because the queries lack profile ID checks. An attacker needs only a low-privileged member account, and the flaw has a CVSS 4.0 score of 5.3.
