CVE-2026-53814 OpenClaw < 2026.5.20 - Privilege Escalation via Hook-Triggered CLI MCP Tool Authority

OpenClaw before 2026.5.20 contains a privilege escalation vulnerability where hook-triggered agent runs incorrectly receive owner-scoped MCP loopback authority instead of hook-appropriate scope. Attackers with a valid hook token can exploit the /hooks/agent endpoint to cause spawned CLI runtimes ...

CVE-2026-53814

OpenClaw before 2026.5.20 contains a privilege-escalation vulnerability in which a hook-triggered agent runs with owner-scoped MCP loopback authority instead of the hook-appropriate scope. Attackers with a valid hook token can use the /hooks/agent endpoint to cause spawned CLI runtimes to access ...

CVE-2026-28475

OpenClaw versions prior to 2026.2.13 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually...

EUVD-2026-9921

OpenClaw versions prior to 2026.2.13 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually...

CVE-2026-28475 OpenClaw < 2026.2.13 - Timing Attack via Hook Token Comparison

OpenClaw versions prior to 2026.2.13 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually...

CVE-2026-28475

OpenClaw is affected in versions before 2026.2.13 where hook token validation uses non-constant-time string comparison, enabling remote attackers to infer tokens via timing side-channels across multiple requests. This can gradually compromise authentication tokens, impacting confidentiality and i...

EUVD-2026-9910

OpenClaw versions prior to 2026.2.12 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually...

OpenClaw 安全漏洞

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. OpenClaw suffers from a security vulnerability that stems from the use of non-constant time string comparisons for hook token validation, which can be exploited by an attacker to infer a token via a timed side channel...

GHSA-47Q7-97XP-M272 OpenClaw: Config writes could persist resolved ${VAR} secrets to disk

Summary OpenClaw hooks previously compared the provided hook token using a regular string comparison. Because this comparison is not constant-time, an attacker with network access to the hooks endpoint could potentially use timing measurements across many requests to gradually infer the token. In...

PT-2026-23550

Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.2.13 Description The software uses non-constant-time string comparison for hook token validation, potentially allowing attackers to infer tokens through timing measurements. Remote attackers with network access ...

OpenClaw Hook Session Key Override Enables Targeted Cross-Session Routing

Summary The issue is not deterministic session keys by itself. The exploitable path was accepting externally supplied sessionKey values on authenticated hook ingress, allowing a hook token holder to route messages into chosen sessions. Affected Behavior - POST /hooks/agent accepted payload...
