Local file disclosure via unrestricted file scheme
Published Jul 19, 2026 · Updated Jul 19, 2026
Local file disclosure in Zevorn RT-Claw 0.1 and 0.2.0 allows remote attackers to read process-accessible files via AI tool input. The http_request tool passes its url argument to the Linux libcurl backend without an HTTP(S) scheme allowlist, so file:// reads return file contents in the tool result. Exploitation requires attacker influence over model-generated tool arguments; disclosure is limited to files readable by the RT-Claw process.
