## ⚠️ Behavior Changes

• **OIDC providers with RSA keys larger than 4096 bits.** The fix for CVE-2026-116587 makes go-jose reject RSA keys larger than 4096 bits. Concourse reads the whole key set from your provider's `jwks_uri`. If any key in that set is larger than 4096 bits, every login through the OIDC connector (`--oidc-*` / `CONCOURSE_OIDC_*`) fails with `oidc：failed to decode keys: ... modulus too large`. Large hosted providers use 2048-bit keys. Check self-hosted providers, such as Keycloak with imported keys, before you upgrade. Concourse's own keys are not affected, including the session signing key and the ID-token signing keys.
• **A negative `--concurrent-request-limit` now stops the web node from starting.** For example, `ListAllJobs:-1` now makes the web node exit at startup with `panic：semaphore: size < 0`. Before, a negative limit made every request to that endpoint return 503. To disable the endpoint, use `0`, which returns 501. To limit it, use a positive number. This comes from golang.org/x/sync v0.24.0, which the x/net fix requires.

## 🛡️ Security Fixes

• `concourse` binary：CVE-2026-116587 (go-jose), CVE-2026-78669, CVE-2026-78661 and CVE-2026-97045 (golang.org/x/net), and CVE-2026-84445 (gRPC).
• `gdn`：CVE-2026-111943 (built with go1.27.3).
• Bundled resource types：CVE-2026-111497 (brotli) in every resource type except git, which already had the fix. Also CVE-2026-111943 and CVE-2026-114613 (pip) in hg, and CVE-2026-116587 (containerd) in docker-image.

## 🔓 Known Vulnerabilities

The bundled `containerd` and `runc` binaries are built from their latest upstream releases (containerd v2.4.2, runc v1.5.2). Those releases still carry vulnerable Go dependencies. We will pick up fixed versions in a later patch release once upstream ships them.

| Binary | CVE | Dependency |
|---|---|---|
| `containerd` | CVE-2026-116587, CVE-2026-78669 | go-jose/v4 v4.1.5, golang.org/x/net v0.58.0 |
| `containerd-shim-runc-v2`, `ctr` | CVE-2026-78669 | golang.org/x/net v0.58.0 |
| `runc` | CVE-2026-46600, CVE-2026-78669 | golang.org/x/net v0.55.0 |
