CVE-2026-122236OpenHands improper authentication
CVE-2026-122236 is a improper authentication in OpenHands, rated low (2.1 on CVSS 4.0).
Why this priority: Low severity, with no exploitation signal.
Published · Updated · NVD status: Deferred
What it is
The software does not prove who a caller is, so an attacker can pass as someone else. A function that should require sign-in can be called by anyone.
How it is reached
An attacker can exploit it from the same local network segment, without an account, and nobody has to click anything.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker act as a signed-in user, or an administrator, without valid credentials.
Is it being exploited?
CISA's SSVC assessment notes a public proof of concept. EPSS estimates a 0.36% chance of exploitation activity in the next 30 days, higher than 30% of scored CVEs.
What to do
- Upgrade OpenHands to 1.25.0 or later.
- Segment the networks that can reach it.
Description from NVD
A vulnerability has been found in OpenHands up to 1.24.0. This impacts an unknown function of the component Landing Page. Such manipulation leads to missing authentication. The attack must be carried out from within the local network. The exploit has been disclosed to the public and may be used. Upgrading to version 1.25.0 will fix this issue. The name of the patch is c5efa3ae415def0a903c82d2b17b748e663b1995. Upgrading the affected component is recommended.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Sign-in, session and token handling. The flaw sits between anonymous callers and authenticated sessions.
- Identity providers and SSO. The flaw sits between anonymous callers and authenticated sessions.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- Between anonymous callers and authenticated sessions. An attacker who crosses it can act as a signed-in user, or an administrator, without valid credentials.
Questions to answer about your own systems
- Where does OpenHands run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
