CVE-2026-101112 · Severity: info · Published 2026-09-29

Balbooa Forms, a Joomla extension for building online forms, contains a vulnerability that allows unauthorized deletion of file attachments. An attacker can delete temporary attachments uploaded by other users by exploiting insufficient authorization checks in the attachment removal function, even though the system verifies session tokens to prevent cross-site attacks.

## Technical details

The removeTmpAttachment action in Balbooa Forms accepts an attachment ID and removes the corresponding file and database entry. While the controller validates a Joomla session token to prevent CSRF, the model layer does not verify that the attachment belongs to the requesting user, the correct form, or the correct upload field. An unauthenticated guest can obtain a valid session token and use it to delete any temporary attachment by ID, as the authorization logic is incomplete.
