authentik vs Harbor: at a glance
What is authentik?
authentik patches 2026.8 and 2026.5 together, with cert updates after the eMudhra CA compromise.
authentik is in maintenance mode on its release branches. 2026.8.5 fixes an endpoints MultipleObjectsReturned error, skips members already in Microsoft Entra groups during sync, stops the Agents tab flashing for unlicensed users, and bumps certificate dependencies after the eMudhra CA compromise. 2026.5.8 backports a longer list, including a consent re-grant error, websocket header handling and pool credential refresh.
What is Harbor?
Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.
Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.

authentik
5.0INFRA · APIS
authentik patches 2026.8 and 2026.5 together, with cert updates after the eMudhra CA compromise.
◆ Current state
authentik is in maintenance mode on its release branches. 2026.8.5 fixes an endpoints MultipleObjectsReturned error, skips members already in Microsoft Entra groups during sync, stops the Agents tab flashing for unlicensed users, and bumps certificate dependencies after the eMudhra CA compromise. 2026.5.8 backports a longer list, including a consent re-grant error, websocket header handling and pool credential refresh.
◆ Where it's heading
Since the 2026.8.0 Agent and Actors release, every entry has been a patch on 2026.8 or an older branch, and the team keeps three branches supported. The fixes are concentrated in sync providers, the proxy outpost and the new Agents UI.
◆ Prediction
Expect further 2026.8.x patches and a 2026.11 release candidate; the entries don't yet show what the next feature release contains.
Harbor
5.0INFRA · APIS
Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.
◆ Current state
Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.
◆ Where it's heading
Harbor's recent releases are split between security hardening and undoing the parts of that hardening that broke real deployments. Both supported lines now carry the rollbacks, and new work is CVE fixes rather than features.
◆ Prediction
Expect 2.14.6 and 2.15.4 finals shortly; the entries don't show a 2.16 feature release yet.
