CVE-2023-51419Network attack vector

Unauthenticated file upload via missing type validation

Published Dec 29, 2023 · Updated Apr 28, 2026

Unrestricted file upload in Bertha AI WordPress Plugin 1.11.10.7 and earlier allows remote attackers to write files to the server. The bthai_wa_translate_audio_callback function accepts uploaded audio without validating the file type before storing it. No authentication or user interaction is required; a server-executable upload grants code execution with the web server account's privileges.
