Summary
OpenClaw: Assistant media route missed scope enforcement for trusted-proxy authorization
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
< 2026.4.20 - Patched version:
2026.4.20
Release
Fixed in OpenClaw 2026.4.20.
Impact
The Control UI assistant-media route authenticated trusted-proxy callers but did not enforce the declared operator scopes for identity-bearing HTTP auth paths. A trusted-proxy caller without operator.read could access assistant-media files and metadata that were otherwise inside allowed media roots.
The route still required successful gateway authentication and media-root checks. Severity is low.
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.
CVE-2026-41908 has a CVSS score of 4.3 (Low). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2026.4.20); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Assistant-media file and metadata requests now require operator.read on identity-bearing HTTP auth paths.

Frequently Asked Questions
- What is CVE-2026-41908? CVE-2026-41908 is a low-severity incorrect authorization vulnerability in openclaw (npm), affecting versions < 2026.4.20. It is fixed in 2026.4.20. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- How severe is CVE-2026-41908? CVE-2026-41908 has a CVSS score of 4.3 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of openclaw are affected by CVE-2026-41908? openclaw (npm) versions < 2026.4.20 is affected.
- Is there a fix for CVE-2026-41908? Yes. CVE-2026-41908 is fixed in 2026.4.20. Upgrade to this version or later.
- Is CVE-2026-41908 exploitable, and should I be worried? Whether CVE-2026-41908 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-41908 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
