What is CircleCI?

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

What is mod_auth_openidc?

mod_auth_openidc 2.4.20.4 closes a provider-to-host command execution path.

This Apache module implements OpenID Connect relying-party support, and its 2.4.20.x line has been a sustained security programme. 2.4.20.4 fixes a case where a provider could have a command run on the host via the exec: prefix in client metadata, sub-request session reuse that exposed protected content, a front-channel logout that could end another user's session, and quadratic memory use on large responses. It also adds interval-based access token refresh, cache metrics and a real readiness probe.

7.5

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

◆ Current state

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

◆ Where it's heading

The platform keeps pulling identity and permission checks onto the real actor: scoped tokens, V3 OIDC claims and re-run attribution. The self-hosted line follows with its own permission and link repairs. Server 5.0 is taking shape as a breaking release, at least for secret storage.

◆ Prediction

Expect more Server 4.x patches ahead of 5.0, with Tink migration guidance repeated until Vault support ends.

2.5

mod_auth_openidc 2.4.20.4 closes a provider-to-host command execution path.

◆ Current state

This Apache module implements OpenID Connect relying-party support, and its 2.4.20.x line has been a sustained security programme. 2.4.20.4 fixes a case where a provider could have a command run on the host via the exec: prefix in client metadata, sub-request session reuse that exposed protected content, a front-channel logout that could end another user's session, and quadratic memory use on large responses. It also adds interval-based access token refresh, cache metrics and a real readiness probe.

◆ Where it's heading

Each 2.4.20.x release has taken one area through review: session crypto, the state-cookie parser, cache storage, and now metadata handling, sub-requests and logout. Observability is the second thread, with Prometheus self-health metrics and trace propagation added in this release.

◆ Prediction

Further 2.4.20.x security releases are likely while the review continues. The sub-request change can trigger re-authentication where OIDCStripCookies or POST-body tokens are used, so operators should test before upgrading.
