CVE-2026-16120Public exploitNetwork attack vector

Authenticated command execution via basename collision

Published Jul 18, 2026 · Updated Jul 18, 2026

Authorization bypass in GoClaw 3.13.3-beta.0 through 3.13.3-beta.3 allows remote authenticated users to execute workspace binaries. matchesAllowlist compares an allowlist entry with the basename returned by extractBin, while host execution retains the attacker-controlled relative path. Operator access, allowlist mode, and the ability to place a same-name executable in the selected workspace are required; the binary runs with the GoClaw process privileges.
