What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

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.

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.

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.
