DescriptionCVE.org

OpenClaw before 2026.3.25 contains an authorization bypass vulnerability in Google Chat group policy enforcement that relies on mutable space display names. Attackers can rebind group policies by changing or colliding space display names to gain unauthorized access to protected resources.

AnalysisAI

OpenClaw before version 2026.3.25 contains an authorization bypass vulnerability in Google Chat group policy enforcement where attackers with authenticated access can manipulate space display names to rebind group policies and gain unauthorized access to protected resources. The vulnerability requires authenticated access and high attack complexity but affects confidentiality and integrity of protected data. A vendor patch has been released.

Technical ContextAI

The vulnerability resides in OpenClaw's implementation of Google Chat group policy enforcement mechanisms (CWE-807: Reliance on Untrusted Inputs in a Security Decision). The root cause is the use of mutable space display names as a security-relevant identifier for binding and enforcing group policies. When display names are used as policy anchors without proper immutable validation or cryptographic binding, attackers can manipulate these attributes through legitimate space modification operations. This allows policy rebinding attacks where an attacker can either change a display name to match a target space (collision) or rename their own space to match a protected resource's display name, causing policy enforcement logic to incorrectly apply or transfer access controls. The affected product is OpenClaw (CPE: cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:*:*:*) in all versions prior to 2026.3.25.

RemediationAI

Vendor-released patch: upgrade to OpenClaw version 2026.3.25 or later. The upstream fix is available at the commit referenced (11ea1f67863d88b6cbcb229dd368a45e07094bff) in the OpenClaw GitHub repository. Organizations unable to upgrade immediately should audit existing group policy configurations for suspicious display name changes or collisions, implement monitoring on space display name modifications, and restrict policy modification permissions to trusted administrators.
