Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Grav (Packagist getgrav/grav) versions before 2.0.16 are vulnerable to path traversal in MediaUploadTrait::deleteFile(), where the directory portion of a filename is not validated before a file is removed. An authenticated user with media management permissions could use this to delete arbitrary files on the server, such as configuration or account files, which could also cause denial of service. Upgrade to version 2.0.16, which is listed as the fixed version.
