CVE-2026-77931Network attack vector

Remote code execution via indirect prompt injection

Published Oct 15, 2026 · Updated Oct 15, 2026

Prompt injection in jxxghp MoviePilot 3.1.5 and earlier allows remote attackers to execute OS commands through the AI assistant. ExecuteCommandTool accepts model-generated commands and a model-settable confirmation flag that bypasses its safety denylist, allowing instructions in untrusted external content to reach the shell. Exploitation requires an administrator's assistant to process attacker-controlled content; commands execute with the MoviePilot process's permissions.
