Authelia vs Quay
A side-by-side editorial comparison of Authelia and Quay — release velocity, themes, recent moves, and the top alternatives to consider.

Authelia vs Quay: at a glance
What is Authelia?
Authelia patches two access control bypass paths from canonicalization gaps.
Authelia v4.39.x is in a sustained hardening cycle: a critical security release in May fixed two authentication bypass paths, and subsequent patch releases have worked through a dense queue of OIDC protocol compliance bugs — resource indicators, client credentials foreign key handling, authentication strategy configuration, and resource strategy matching. The pace of micro-patches (v4.39.21 through v4.39.25 in a two-week window) reflects active production use surfacing edge cases.
What is Quay?
Quay ships a series of SSRF fixes in mirroring and proxy cache alongside steady CVE patching across 3.10 and 3.12 branches.
Quay is in maintenance mode, releasing security patches across two active branches. Recent releases closed SSRF vulnerabilities in repository source mirroring and proxy cache upstream configuration, and patched a robot account token exposure to global readonly superusers. The cadence is CVE-reactive with no feature development visible in this window.
Authelia vs Quay: editorial side-by-side
Authelia
5.0INFRA · APIS
Authelia patches two access control bypass paths from canonicalization gaps.
◆ Current state
Authelia v4.39.x is in a sustained hardening cycle: a critical security release in May fixed two authentication bypass paths, and subsequent patch releases have worked through a dense queue of OIDC protocol compliance bugs — resource indicators, client credentials foreign key handling, authentication strategy configuration, and resource strategy matching. The pace of micro-patches (v4.39.21 through v4.39.25 in a two-week window) reflects active production use surfacing edge cases.
◆ Where it's heading
The OIDC fix pattern is deliberate: Authelia is closing gaps in the parts of OAuth 2.0/OIDC that enterprise clients actually use — resource indicators, client credentials grants, pooled authentication. This isn't maintenance drift; it's building toward a more complete OIDC server for complex multi-client deployments. The access control canonicalization fix from May signals a broader audit of how Authelia normalizes domain names and usernames before authorization decisions.
◆ Prediction
The OIDC compliance fixes in v4.39.x are groundwork for new grant types and flows in a future major version. Expect device authorization flow or Pushed Authorization Requests (PAR) to appear in a v4.40 or v5.x roadmap entry once the protocol surface is cleaned up.
Quay
5.0INFRA · APIS
Quay ships a series of SSRF fixes in mirroring and proxy cache alongside steady CVE patching across 3.10 and 3.12 branches.
◆ Current state
Quay is in maintenance mode, releasing security patches across two active branches. Recent releases closed SSRF vulnerabilities in repository source mirroring and proxy cache upstream configuration, and patched a robot account token exposure to global readonly superusers. The cadence is CVE-reactive with no feature development visible in this window.
◆ Where it's heading
No feature work appears in this release window. Quay maintains dual active branches (3.10 and 3.12), reflecting a long support commitment typical of Red Hat products. The SSRF fixes represent real security hardening but no new capability surface. Direction from these entries alone is unclear — the product appears to be in a holding pattern between major versions.
◆ Prediction
The pattern suggests continued CVE-reactive patching. A v3.13 or newer major branch would be the next meaningful event, though nothing in these entries signals when that lands.
