Threats affecting pkg:github/odysseus

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.

Odysseus before commit 87babb5 contains a server-side request forgery (SSRF) vulnerability that allows attackers with admin privileges to make the server send requests to internal network resources. This occurs because the embedding endpoint configuration does not validate the scheme, host, IP range, or DNS rebind, enabling attackers to submit loopback, RFC 1918, or link-local addresses. The vulnerability can be used to partially read responses from internal services such as cloud instance metadata APIs and other internal hosts reachable from the server. The CVSS 4.0 score is 6.1, indicating a medium severity issue. No patch or official remediation guidance is currently available.
