{“lastseen”:””,”description”:”The path allowance check in GeneralUtility::isAllowedAbsPath() performed a plain string prefix comparison without requiring a directory separator boundary, causing a path like \/var\/www\/html-other\/secret.yaml to be incorrectly accepted as valid when the project root was \/var\/www\/html.
