OpenHands Software Agent SDK: Binding to an Unrestricted IP Address
CVE-2026-112346 is a critical-severity binding to an unrestricted IP address vulnerability in OpenHands Software Agent SDK from OpenHands, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.52.0 as the first without the flaw, so updating OpenHands Software Agent SDK to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.01% chance of exploitation within 30 days, higher than 64% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update OpenHands Software Agent SDK to 1.52.0 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
OpenHands Software Agent SDK before 1.52.0 contains an unauthenticated remote code execution vulnerability where the DockerWorkspace and Apptainer workspace launchers bind the sandbox agent server to all network interfaces (0.0.0.0) with an empty session_api_keys list, disabling authentication by default. Attackers who can reach the published container port can send unauthenticated HTTP and WebSocket requests to execute arbitrary shell commands as root in the sandbox, access the mounted workspace, and read plaintext secrets from the secrets store.

The underlying weakness: Binding to an Unrestricted IP Address
The product assigns the address 0.0.0.0 for a database server, a cloud service/instance, or any computing resource that communicates remotely.
How developers prevent this class of flaw
- Assign IP addresses that are not 0.0.0.0.
- Unwanted connections to the configured server may be denied through a firewall or other packet filtering measures.
