AI-suggested
Fixed versions 6.8.181, 25.0.116, and 26.0.58 are available and should be applied to remediate this vulnerability. Users of affected versions should upgrade to these releases to ensure proper authorization checks are enforced on form report downloads.
Description
Intermesh Group-Office versions before 6.8.181, 25.0.116, and 26.0.58 have a missing authorization vulnerability. Authenticated users can download form reports via the api/download.php endpoint without proper permission checks. This allows unauthorized export of form submissions as XLSX files, potentially exposing sensitive data.
