What is CVE-2026-32897?

The vulnerability in OpenClaw versions before 2026.2.22 allows an attacker to exploit the dual-use of the gateway authentication token. When the owner-ID prompt obfuscation is set to use a fallback hash secret and the corresponding display secret is unset, the gateway's authentication secrets can be compromised. Attackers who gain access to system prompts transmitted to external model providers can derive authentication tokens from hashed outputs, potentially undermining gateway security and access controls.
