CVE-2026-45087Public exploitNetwork attack vector

Unauthenticated code execution via found-action option

Published May 27, 2026 · Updated May 27, 2026

OS command injection in Dalfox before 2.13.0 allows remote attackers to execute arbitrary commands through the REST API server. POST /scan binds attacker-controlled FoundAction and FoundActionShell values into scan options, and foundAction passes the command to the chosen shell after a finding. Exploitation requires reachable server mode without an API key and a scan target that produces a finding, granting the Dalfox process's host privileges.
