Clair vs Woodpecker CI: at a glance
What is Clair?
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
What is Woodpecker CI?
Woodpecker CI hardens agent security and forge handling through its 3.14 release candidates
Woodpecker is iterating through 3.14.0 release candidates focused on security and agent/forge robustness: sanitizing agent-introduced state changes and log streaming, blocking registration as arbitrary agents, restricting log access, and cleaning up the Forge interface. Dependency security bumps (axios, otel, follow-redirects) and a lodash removal run throughout.

Clair
2.5INFRA · APIS
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
◆ Current state
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
◆ Where it's heading
Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.
◆ Prediction
More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
Woodpecker CI

Woodpecker CI hardens agent security and forge handling through its 3.14 release candidates
◆ Current state
Woodpecker is iterating through 3.14.0 release candidates focused on security and agent/forge robustness: sanitizing agent-introduced state changes and log streaming, blocking registration as arbitrary agents, restricting log access, and cleaning up the Forge interface. Dependency security bumps (axios, otel, follow-redirects) and a lodash removal run throughout.
◆ Where it's heading
The 3.14 line reads as a security-and-internals hardening cycle, tightening the agent trust boundary and forge integration rather than pushing features. The earlier 3.11 line shows the more typical mix of per-repo config features and fixes.
◆ Prediction
Expect 3.14.0 to converge to a stable release after the RC series, continuing the agent-security and forge-handling focus.
