Auth bypass in Balbooa.com Balbooa Forms Extension For Joomla

CVE-2026-101112

Joomla Extension - balbooa.com - Unauthorized Deletion of Attachments in Balbooa Forms < 2.4.3.4 - The public removeTmpAttachment action accepts an integer attachment ID and deletes the matching database row and file. The controller verifies a Joomla session token, but the model does not bind that ID to the session that uploaded the file, the current user, the form, the upload field, or the temporary state. Any guest can obtain a token for their own session, so the token prevents CSRF but does not authorize the target object.

Vulnerability class: IDOR (Insecure Direct Object Reference)
