Authenticated log-file disclosure via argument injection
Published May 12, 2026 · Updated May 12, 2026
Argument injection in Fortinet FortiDeceptor allows remote authenticated users to read log files through crafted HTTP requests. The HTTP log-file retrieval path passes request-controlled input into a command without neutralizing argument delimiters; Fortinet has not disclosed the endpoint or command. At least read-only administrative permission is required, and the documented consequence is limited to disclosure of log-file contents.
