IMPACT: Unauthenticated remote attackers can upload arbitrary PHP files to attacker-controlled filesystem paths. Missing permission checks, nonce verification, and file-type validation allow malicious PHP uploads that can lead to server-side code execution. EXPLOITATION STATUS: CONFIRMED VULNERABILITY. No verified in-the-wild exploitation or public working PoC identified. Forensic triage: Inspect unexpected PHP files, suspicious upload requests, unauthorized filesystem modifications, and unusual web-server processes. Review recent access logs for anomalous requests involving plugin upload functionality. No confirmed CVE-specific malicious IOCs have been published. URGENT ACTION: Disable or remove vulnerable Anton Extensions installations until a verified security fix is available. Restrict file-upload capabilities and prevent PHP execution in upload directories. Investigate suspicious server activity.
