CVE-2026-32031: OpenClaw < 2026.2.26 - Authentication Bypass via Path Canonicalization Mismatch in /api/channels Gateway

Noroxi assessment

Priority: Monitor (action score 25/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: OpenClaw OpenClaw 2026.2.26.

Low priority for now. Upgrade to OpenClaw OpenClaw 2026.2.26 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

OpenClaw versions prior to 2026.2.26 server-http contains an authentication bypass vulnerability in gateway authentication for plugin channel endpoints due to path canonicalization mismatch between the gateway guard and plugin handler routing. Attackers can bypass authentication by sending requests with alternative path encodings to access protected plugin channel APIs without proper gateway authentication.
