CVE-2026-122236: OpenHands Landing missing authentication
Noroxi assessment
Priority: Monitor (action score 8/100)
- 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: 0.36% (FIRST EPSS).
- Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: n/a OpenHands 1.25.0.
- Severity is disputed: the assigning authority (CNA) scores it 5.3, NVD 2.1.
Low priority for now. Upgrade to n/a OpenHands 1.25.0 or later.

Root cause
Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.
