Summary

CVE-2026-6987 is a medium-severity Injection (CWE-74) vulnerability in Sipeed Picoclaw. Its CVSS base score is 5.5 (Medium).

Operationally, ranked in the top 8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A vulnerability has been identified in PicoClaw versions up to 0.2.4 within the Web Launcher Management Plane component. Specifically, an unauthenticated remote manipulation of the /api/gateway/restart endpoint can trigger command injection, as classified under CWE-74 and CWE-77. The issue was reported through a project issue tracker prior to public disclosure on 2026-04-25, but the maintainers have not issued a response.

Remote attackers can exploit the flaw without requiring credentials or user interaction to execute arbitrary commands on the affected system. Successful exploitation yields limited effects on confidentiality, integrity, and availability according to the CVSS 5.5 rating, with the attack vector rated as network-accessible and low complexity.

References including the GitHub issue report and Vuldb entries contain no details on patches, workarounds, or official mitigation guidance. The EPSS probability rose from a low baseline to a peak of 0.0214 on 2026-05-01 before receding, indicating a temporary increase in exploitation interest following disclosure.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

finds

Security testing in development catches injection vulnerabilities before release.

finds

Monitoring activities can identify active injection attacks after they occur.

prevents

Secure coding standards require proper neutralization of special elements, directly addressing CWE-74.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-74, a class-level weakness, and none of its children carries one either.
  • No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
