CVE-2026-43624
Last modified
CVE-2026-43624 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
