Authentication Bypass in OpenClaw /api/channels via Encoding Flaw

Publication date: 2026-03-19

Last updated on: 2026-03-23

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.3.2 contain an authentication bypass vulnerability in the /api/channels route classification due to canonicalization depth mismatch between auth-path classification and route-path canonicalization. Attackers can bypass plugin route authentication checks by submitting deeply encoded slash variants such as multi-encoded %2f to access protected /api/channels endpoints.

Executive Summary

This vulnerability exists in OpenClaw versions prior to 2026.3.2 and involves an authentication bypass in the /api/channels route. The issue arises due to a mismatch in how the system classifies the authentication path versus how it canonicalizes the route path. Attackers can exploit this by submitting deeply encoded slash variants, such as multi-encoded %2f characters, to bypass authentication checks and gain unauthorized access to protected /api/channels endpoints.

Impact Analysis

This vulnerability can allow attackers to bypass authentication controls and access protected API endpoints without proper authorization. This could lead to unauthorized access to sensitive data or functionality within the OpenClaw system, potentially compromising the integrity and confidentiality of the affected system.
