Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-w9x9-j56r-h98r affects the npm package @eeacms/volto-chatbot in versions before 2.0.4. Its Express middleware forwards unauthenticated requests on the /_v1_da/ path to the configured Danswer API, attaching the server's own Danswer credentials. An unauthenticated network attacker could therefore call arbitrary Danswer endpoints, including admin and write operations, with the service account's permissions. Upgrade to @eeacms/volto-chatbot 2.0.4, which is listed as the fixed version.

Written 31 Oct 2026.
