Unauthenticated command execution via crafted network request
Published Feb 20, 2026 · Updated Feb 20, 2026
Command injection in Owl Cyber Defense OPDS 2.2.0.4 and earlier allows remote attackers to execute commands via a crafted network request. The public advisory does not identify the affected endpoint, parameter, command-construction path, or shell invocation that mishandles input. No authentication or user interaction is required, but exploitation depends on an unspecified attack condition and can compromise data and service availability.
