Authelia v4.39.19 released on 12-04-2026
Authelia v4.39.19 is out now. It fixes inconsistent OAuth2 error messages, tightens issuer validation in middlewares with a domain suffix check and clearer issuer error text, and corrects a healthcheck timing bug so healthchecks see the correct environment values.
For full details and the published images, see the project release on GitHub; Docker images are available as authelia/authelia:4.39.19 and ghcr.io/authelia/authelia:4.39.19.
What’s in this release
- handlers: OAuth2 — inconsistent error messages fixed so request handler responses are uniform (issue #11745)
- middlewares: issuer validation — adds/clarifies a domain suffix check and corrects a misleading issuer error message (issues #11758, #11749)
- server: healthcheck — environment variables were written too late; healthchecks now see the correct environment values (issue #11639)
