No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
