upload_handler.php in the swfupload extension in Chyrp 2.0 and earlier relies on client-side JavaScript code to restrict the file extensions of uploaded files, which allows remote authenticated users to upload a .php file, and consequently execute arbitrary PHP code, via a write_post action to the default URI under admin/.

Security readout for executives and security teams

Chyrp 2.0 and earlier allowed authenticated users to bypass upload restrictions because file type checks were handled in browser JavaScript. A user with access to the admin posting workflow could upload a PHP file, creating a path to server-side code execution. Exposure is likely limited to Chyrp 2.0 and earlier installations with the swfupload extension and authenticated access to admin posting or upload functionality. The source bundle does not identify CPEs or broader affected products. Treat as high priority for legacy Chyrp deployments because compromise can become server code execution. Priority is lower where Chyrp is not present, swfupload is disabled, or only highly trusted administrators can upload content. Mitigation focus: Check Chyrp or vendor guidance for fixed versions or advisories.; Disable the swfupload extension if it is not required.; Enforce upload file type and content validation server-side..
