Authorization Bypass in OpenClaw Tools via Identifier Collision

Publication date: 2026-03-19

Last updated on: 2026-03-23

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.2.22 contain an authorization bypass vulnerability in the toolsBySender group policy matching that allows attackers to inherit elevated tool permissions through identifier collision attacks. Attackers can exploit untyped sender keys by forcing collisions with mutable identity values such as senderName or senderUsername to bypass sender-authorization policies and gain unauthorized access to privileged tools.

Executive Summary

OpenClaw versions prior to 2026.2.22 have an authorization bypass vulnerability related to the toolsBySender group policy matching. This vulnerability allows attackers to gain elevated tool permissions by exploiting identifier collision attacks.

Specifically, attackers can exploit untyped sender keys by forcing collisions with mutable identity values such as senderName or senderUsername. This enables them to bypass sender-authorization policies and gain unauthorized access to privileged tools.

Impact Analysis

This vulnerability can allow attackers with limited privileges to bypass authorization controls and gain unauthorized access to privileged tools within OpenClaw.

As a result, attackers could perform actions or access resources that should be restricted, potentially leading to misuse or compromise of sensitive operations.
