CVE-2026-25253 is a high-severity vulnerability affecting OpenClaw, also known as clawdbot or Moltbot. The vulnerability arises from the software's handling of the gatewayUrl value obtained from a query string, which it uses to automatically establish a WebSocket connection. This occurs without any user prompt, leading to the unintentional transmission of sensitive token values. With a CVSS score of 8.8, this vulnerability poses a significant risk to organizations utilizing OpenClaw, as it could lead to unauthorized access and data exfiltration.
The urgency for defenders is heightened due to the nature of this vulnerability. Attackers may leverage this issue to gain access to sensitive information, especially considering its exploitability is classified as high. Given the potential impact on confidentiality, integrity, and availability, organizations should prioritize patching immediately.
As of now, this vulnerability has been confirmed with known exploits available. Organizations using OpenClaw should act swiftly to assess their systems for this vulnerability and implement necessary mitigation strategies.
Recent reports indicate that the vulnerability has been actively discussed in the security community, further underlining the importance of immediate attention by affected organizations.
Vulnerability Details
OpenClaw (aka clawdbot or Moltbot) before version 2026.1.29 obtains a gatewayUrl value from a query string and automatically makes a WebSocket connection without prompting, sending a token value. The vulnerability is classified under CWE-669.
The CVSS score for this vulnerability is 8.8, indicating a high severity level. The attack vector is network-based, and the attack complexity is low. No privileges are required for exploitation, but user interaction is necessary.
The confidentiality, integrity, and availability impacts are all rated high, emphasizing the critical nature of this vulnerability.
This vulnerability was published on February 1, 2026.
Technical Analysis
The root cause of this vulnerability lies in how OpenClaw processes the gatewayUrl from a query string. By automatically establishing a WebSocket connection, the application fails to solicit user consent, which is a critical oversight in secure application design.
The attack vector is categorized as network-based, allowing an adversary to exploit this vulnerability remotely. The low attack complexity indicates that an attacker does not require advanced skills to exploit this flaw. Furthermore, since no privileges are needed to initiate this attack, it poses a significant risk to organizations.
User interaction is required for exploitation, which may involve tricking a user into clicking a malicious link or visiting a compromised page. The impacts on confidentiality, integrity, and availability are rated high, confirming the serious nature of the vulnerability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, which could lead to data breaches and significant reputational damage. The blast radius for this vulnerability is extensive, as any instance of OpenClaw that is deployed and not updated is susceptible to attack.
Given the CVSS score of 8.8, organizations must evaluate their exposure to this vulnerability and act accordingly. The urgency for remediation is high, and organizations should address this in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of OpenClaw are all versions prior to 2026.1.29. Organizations should ensure they are running the latest version to mitigate this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching immediately by updating OpenClaw to version 2026.1.29 or later. In cases where an immediate patch is not possible, organizations should implement configuration changes to block unauthorized WebSocket connections.
Additionally, organizations should consider employing network controls to monitor for any anomalous WebSocket traffic that may indicate exploitation attempts.
For further guidance on proactive security measures, organizations can explore penetration testing services which can help identify and remediate similar vulnerabilities.
Detection Guidance
Organizations should monitor their logs for indicators of unauthorized WebSocket connections. Behavioral anomalies in application usage may also signal an attempted exploitation of this vulnerability.
Network signatures should be established to detect unexpected WebSocket traffic. Additionally, changes to system configurations that do not align with normal operational parameters should be flagged for review.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2026-25253 highlights the ongoing challenges of secure application design, especially in systems that rely on user input for establishing critical connections. This vulnerability represents a pattern of oversight that security teams must be vigilant against.
Security teams should learn from this incident and implement rigorous validation of user inputs, particularly in scenarios involving network connections. The strategic takeaway is to prioritize user consent and transparency in application behavior.
