Machine-written summary

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

Coder's Go package github.com/coder/coder/v2 is affected in versions before 2.29.17, from 2.30.0 before 2.32.7, from 2.33.0 before 2.33.8, and from 2.34.0 before 2.34.2. An unauthenticated attacker who submits a login with the password "hunter2" can tell whether an account exists and which authentication method it uses, because the response codes differ. No authentication bypass or data access results. Upgrade to 2.29.17, 2.32.7, 2.33.8, or 2.34.2 depending on your release line; no workaround is listed.
