Authentication Bypass

Description

OpenClaw before 2026.3.22 contains an identity spoofing vulnerability in ACP permission resolution that trusts conflicting tool identity hints from rawInput and metadata. Attackers can spoof tool identities through rawInput parameters to suppress dangerous-tool prompting and bypass security restrictions.

Analysis

OpenClaw before version 2026.3.22 allows authenticated remote attackers to spoof tool identities through rawInput parameters, bypassing ACP permission resolution and suppressing dangerous-tool prompting via identity hint conflicts between rawInput and metadata. This authentication bypass with high integrity impact affects all versions prior to the fixed release, enabling attackers to circumvent security restrictions intended to prevent execution of dangerous operations.
