DescriptionCVE.org

pH7Builder (pH7 Social Dating CMS) before 18.5.0 contains an improper authorization vulnerability in the note module delete() action that allows authenticated members to delete other members' note comments and categories. Attackers can submit another member's note ID in the POST id parameter to remove all comments and category associations, since those queries lack profile ID checks.

AnalysisAI

pH7Builder (pH7 Social Dating CMS) before 18.5.0 contains an improper authorization (IDOR) flaw in the note module's delete() action that lets any authenticated member delete note comments and category associations belonging to other members by submitting the victim's note ID in the POST 'id' parameter. The impact is integrity-only and scoped to note-module comment/category data (CVSS 3.1 base 5.3, PR:L), not full account or site compromise. …
