Summary

Odysseus before commit bf325f6 contains a missing authorization vulnerability that allows authenticated non-admin users to manage server-wide embedding backend configuration. Attackers can overwrite the configuration, leading to data exfiltration to an attacker-controlled destination or denial of service.

Risk Assessment

An attacker can intercept sensitive data sent to the embedding backend or deny service, posing a serious threat to confidentiality and availability.

Recommendation

Upgrade to a version containing the fix (after commit bf325f6) and review endpoint configurations.

Other vulnerabilities in Odysseus

CVE-2026-70620Medium
The SSRF vulnerability in Odysseus before commit 87babb5 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 to partially read responses from cloud instance metadata services, internal APIs, and other hosts reachable from the server.

Original NVD description (English source)

Odysseus before commit bf325f6 contains a missing authorization vulnerability that allows authenticated non-admin users to manage server-wide embedding backend configuration by invoking endpoint management routes that verify session authentication but omit the admin authorization guard. Attackers can supply an attacker-controlled URL to overwrite the embedding backend persisted in the endpoint configuration file and process environment, causing all subsequent embedding operations including chat messages, RAG queries, memory entries, and vault text to be transmitted in plaintext to the attacker-controlled destination, or delete the endpoint configuration to deny embedding service to all users.
