DescriptionCVE.org

OpenClaw before 2026.5.22 contains a locality validation vulnerability in Control UI pairing that allows attackers with network access to spoof locality information and obtain durable admin-capable device tokens. Attackers can exploit insufficient locality-derived trust validation to convert temporary shared access into persistent administrative credentials that survive token rotation.

AnalysisAI

Authentication bypass in OpenClaw before 2026.5.22 allows authenticated network attackers to spoof locality information during Control UI device pairing and escalate temporary shared access into durable, admin-capable device tokens that persist across token rotation. The flaw stems from insufficient locality-derived trust validation (CWE-290), enabling lateral conversion of low-privilege sessions into persistent administrative credentials. No public exploit identified at time of analysis, but a vendor patch and VulnCheck advisory are available.

Technical ContextAI

OpenClaw's Control UI pairing flow uses locality signals (network proximity or origin indicators) as an implicit trust factor when issuing device tokens. CWE-290 (Authentication Bypass by Spoofing) applies here because the pairing logic relies on attacker-influenceable locality data rather than cryptographically bound peer identity, so a remote actor can present forged locality context and receive tokens with administrative capability. The CPE cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:*:*:* covers all OpenClaw application versions prior to 2026.5.22. Crucially, the tokens issued in this flow are durable and survive normal token rotation, meaning the trust decision made during pairing has long-lived security consequences rather than being a transient session artifact.

RemediationAI

Vendor-released patch: OpenClaw 2026.5.22 - upgrade to this version or later per the GHSA-chr9-m4q2-76hw advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-chr9-m4q2-76hw. Until the upgrade is deployed, restrict network reachability of the Control UI pairing endpoint to trusted management networks or a VPN to deny attackers the ability to present spoofed locality (trade-off: legitimate remote pairing workflows will break), and revoke any device tokens issued during the vulnerable window because they persist through rotation and a passive patch will not invalidate already-minted admin-capable tokens. Disable or tightly scope temporary shared-access features that can be escalated through pairing if your deployment supports doing so, accepting reduced collaboration convenience as the trade-off.
