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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://aydinnyunus.github.io/2026/06/16/odysseus-embedding-endpoint-takeover/","tags":[]},{"url":"https://github.com/odysseus-dev/odysseus/commit/bf325f6b2185cb42bc5d8f5713a64aecffb766d4","tags":[]},{"url":"https://github.com/odysseus-dev/odysseus/issues/132","tags":[]},{"url":"https://github.com/odysseus-dev/odysseus/issues/80","tags":[]},{"url":"https://www.vulncheck.com/advisories/odysseus-missing-admin-authorization-via-embedding-endpoint-routes","tags":[]}],"exploitRefs":[{"url":"https://github.com/odysseus-dev/odysseus/commit/bf325f6b2185cb42bc5d8f5713a64aecffb766d4","tags":[]},{"url":"https://github.com/odysseus-dev/odysseus/issues/132","tags":[]},{"url":"https://github.com/odysseus-dev/odysseus/issues/80","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows authenticated non-admin users to manage server-wide embedding backend configuration, leading to plaintext transmission of sensitive data or denial of service.","exploitability":"Exploitation is moderate as it requires an authenticated session but no admin privileges, and attackers can supply attacker-controlled URLs.","blast_radius":"If exploited, this could result in unauthorized plaintext transmission of sensitive data or denial of embedding service to all users.","remediation":"Upgrade to the version containing commit bf325f6 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","config","plaintext","web"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-30T09:21:44.098Z"}}
