No CVSS score has been assigned to CVE-2026-35629 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-35629?

CVE-2026-35629 affects the following packages: openclaw (npm). Ecosystems affected: npm.

How do I fix CVE-2026-35629?

Update openclaw to 2026.3.28 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-35629 is resolved across your whole dependency graph.

How do I detect CVE-2026-35629 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-35629 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-35629?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-35629 can be triaged on real exposure rather than presence alone.

Is CVE-2026-35629 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-35629 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-35629?

CVE-2026-35629 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 16th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-35629?

CVE-2026-35629 is classified as Server-Side Request Forgery (SSRF) (CWE-918). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2026-35629 published, and has it been updated?

CVE-2026-35629 was published on April 9, 2026 and was last updated on September 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

SSRF via Unguarded Configured Base URLs in Multiple Channel Extensions (Incomplete Fix for CVE-2026-28476)

Affected Packages / Versions

Package: openclaw
Affected versions: <= 2026.3.24
First patched version: 2026.3.25
Latest published npm version at verification time: 2026.3.24

Details

Several channel extensions still used raw fetch() against configured base URLs without the SSRF guard that was added for CVE-2026-28476. Commit f92c92515bd439a71bd03eb1bc969c1964f17acf routes those outbound requests through fetchWithSsrFGuard so configured endpoints cannot be rebound to blocked internal destinations.

Verified vulnerable on tag v2026.3.24 and fixed on main by commit f92c92515bd439a71bd03eb1bc969c1964f17acf.
