The provided information does not specify any direct impact of CVE-2026-42430 on compliance with common standards and regulations such as GDPR or HIPAA.
Can you explain this vulnerability to me?
CVE-2026-42430 is a Server-Side Request Forgery (SSRF) vulnerability in the OpenClaw package before version 2026.4.8. It specifically involves the Playwright redirect handling mechanism, which allows attackers to bypass strict SSRF protections implemented by the browser.
The vulnerability occurs because the SSRF protection fails to detect request-time navigation redirects to private network targets, enabling attackers to access internal resources that should normally be restricted.
This issue affects OpenClaw versions prior to 2026.4.8 and was fixed in that version.
How can this vulnerability impact me? :
This vulnerability can allow attackers to bypass browser SSRF protections and access private or internal network targets that should be restricted.
Such unauthorized access to internal resources can lead to information disclosure or further exploitation within a private network.
The severity of this vulnerability is rated as moderate, indicating a significant but not critical risk.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should update OpenClaw to version 2026.4.8 or later, where the SSRF bypass issue in Playwright redirect handling has been fixed.
This update addresses the failure in SSRF protection mechanisms that allowed request-time navigation redirects to private network targets.
