CVE-2026-43624 Details
Description
F5-TTS through version 1.1.20 contains a path traversal vulnerability in the finetune Gradio handlers that allows unauthenticated attackers to write arbitrary files by passing unsanitized user-supplied project names directly to os.path.join() without validating the resulting path stays within the intended base directory. Attackers can supply absolute path arguments such as /tmp/EVIL to override the base directory entirely and create arbitrary directories with attacker-controlled JSON content at any filesystem path writable by the server process.
A path traversal vulnerability has been identified in F5-TTS versions through 1.1.20. This vulnerability resides within the finetune Gradio handlers, where unsanitized user-supplied project names are directly passed to 'os.path.join()'. The lack of validation allows unauthenticated attackers to manipulate the resulting path, potentially escaping the intended base directory. Exploitation involves supplying absolute path arguments to create arbitrary directories and write attacker-controlled JSON content to any filesystem location writable by the server process.
Users are advised to update to F5-TTS version 1.1.21 or later, where this vulnerability has been patched.
