CVE-2026-125330 1 Harnessrouter 1 Harnessrouter 2026-11-12 7.5 High
HarnessRouter is a self-hosted unified API for agent harnesses. From version 0.4.2 until 0.31.7, routes that accept a session ID or response ID validate only the caller's organization and do not enforce the workspace scope of a non-default workspace API key. A key holder who learns a non-guessable identifier from another workspace in the same organization can read sessions, conversation turns, files, traces, and responses, overwrite files, cancel or delete sessions, and publish share links. The issue does not cross organization boundaries, and console users, organization keys, and Default Workspace keys intentionally retain organization-wide access. This issue is fixed in version 0.31.7.
CVE-2026-125331 1 Harnessrouter 1 Harnessrouter 2026-11-12 9.1 Critical
HarnessRouter is a self-hosted unified API for running agent harnesses with sessions, streaming, files, cancellation, and failure handling. Prior to 0.31.8, a console that is not in self-hosted mode attaches the server's internal key to requests carrying an Authorization header before validating the bearer, while the service-only PUT and GET /v1/orgs/{org}/connections/{name}, PUT /v1/orgs/{org}/policy/{backend}, and /internal/* routes trust that key and take the organization from the URL. In a multi-organization deployment, a remote caller can use a made-up bearer to rewrite another organization's provider connection to an attacker-controlled endpoint, causing later prompts to be disclosed and attacker-controlled responses to influence tasks. This issue is fixed in version 0.31.8.
CVE-2026-114362 1 Harnessrouter 1 Harnessrouter 2026-10-28 6.3 Medium
A flaw has been found in HarnessRouter up to 0.31.12. This impacts an unknown function of the file gateway/app.py of the component Targets Test Endpoint. Executing a manipulation of the argument base_url can lead to server-side request forgery. The attack may be performed from remote. Upgrading to version 0.31.13 will fix this issue. This patch is called 1c4b1fc1f89737dabd089ac1d1c174a57f764e28. It is suggested to upgrade the affected component.
CVE-2026-114361 1 Harnessrouter 1 Harnessrouter 2026-10-23 5.6 Medium
A vulnerability was detected in HarnessRouter up to 0.31.10. This affects an unknown function of the file gateway/app.py of the component Identity Mode. Performing a manipulation of the argument X-Harness-Org/X-Harness-Member results in improper authorization. The attack is possible to be carried out remotely. The attack is considered to have high complexity. The exploitability is reported as difficult. Upgrading to version 0.31.11 mitigates this issue. The patch is named 48a26cdf9c4544d2c88d1a07f0777f063f1d753f. The affected component should be upgraded.
