CVE-2026-8209 Details
Description
Gibbon versions before v30.0.01 are affected by a path traversal vulnerability resulting in DOS by attempting extraction of web application PHP files, failed .zip extraction results in deletion of the file and a DOS condition. Successful exploitation requires Teacher or higher privileges. Exploitation could result in loss of availability of the web application.
A path traversal vulnerability has been identified in Gibbon versions prior to v30.0.01. This vulnerability allows users with Teacher or higher privileges to manipulate file paths in a way that disrupts normal application operations. Specifically, the issue arises during the report archiving process, where uploaded ZIP files are extracted and then deleted. If the extraction fails, the deletion still occurs, creating a denial-of-service condition. Additionally, the vulnerability can be exploited to execute PHP code by uploading a ZIP file containing a maliciously named PHP file, which is then processed by the application.
Users are advised to update to Gibbon version v30.0.01, which addresses this vulnerability.
