Apereo CAS vs Clair: at a glance
What is Apereo CAS?
Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.
CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.
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.

Apereo CAS
2.5INFRA · APIS
Apereo CAS 8.1.0 reaches a third release candidate with 8.0.0 still not final.
◆ Current state
CAS runs long release-candidate trains. 8.0.0 reached RC6 in June without a final in this feed, and the 8.1.0 line has since moved through RC1 in August, RC2 in September and RC3 in October. A 7.3.7.1 patch in June fixed a published OIDC vulnerability on the maintenance branch. The release entries list only documentation links and contributor credits, so their contents are not visible here.
◆ Where it's heading
Candidates arrive about monthly, and 8.1 has overtaken 8.0 as the active line. Without notes in the entries, the feed tracks timing rather than content.
◆ Prediction
An 8.1.0-RC4 or an 8.1.0 final is the next likely entry, on the same roughly monthly rhythm.
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.
