Description
Odysseus before commit 87babb5 contains a server-side request forgery vulnerability that allows admin-privileged attackers to direct the server to probe internal network resources by supplying arbitrary URLs to the embedding endpoint configuration without scheme, host, IP range, or DNS rebind validation. Attackers can submit loopback addresses, RFC 1918 ranges, or link-local addresses through the embedding endpoint API to partially read responses from cloud instance metadata services, internal APIs, and other hosts reachable from the server.

AI Analysis

Impact

A server‑side request forgery flaw exists in the embedding endpoint configuration of Odysseus. An attacker with administrative privileges can supply arbitrary URLs that bypass scheme or host validation, causing the server to request resources inside the internal network. If the attacker points the endpoint at internal services or cloud metadata endpoints, the server may return parts of those responses, enabling disclosure of sensitive internal data or configuration.

Affected Systems

Odysseus, provided by odysseus-dev, is vulnerable in all releases prior to commit 87babb5. The issue is limited to the embedding endpoint configuration as accessed by users with administrative rights.

Risk and Exploitability

The CVSS score of 6.1 indicates a moderate severity vulnerability. No EPSS score is available, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires administrative access to the application and the ability to submit configuration changes. Once performed, the attacker can initiate outbound requests to any internal address, potentially reading responses from cloud instance metadata, internal APIs, or other reachable hosts. The attack vector is inferred to be server‑internal due to the need for administrative privileges, but the risk of internal data exposure is significant.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Deploy the patch that removes the SSRF flaw, corresponding to commit 87babb5 or later
  • Immediately enforce strict input validation on the embedding endpoint, rejecting URLs that target loopback, RFC‑1918, or link‑local addresses
  • Reduce the exposure of the embedding endpoint to trusted administrators only by tightening role‑based access controls
  • Monitor application logs for anomalous outbound requests originating from the embedding endpoint
