GHSA-g27f-9qjv-22pm: OpenClaw log poisoning (indirect prompt injection) via WebSocket headers

OpenClaw versions before 2026.2.13 logged WebSocket request headers (like Origin and User-Agent) without cleaning them up, allowing attackers to inject malicious text into logs. If those logs are later read by an LLM (large language model, an AI system that processes text) for tasks like debugging, the attacker's injected text could trick the AI into doing something unintended (a technique called indirect prompt injection or log poisoning).
