Please do not open a public issue for a security problem in Agent8. Email hello@keelinfra.io with the subject "Agent8 security report", and include:
- what is affected (
install.sh, the Ansible playbook, the agent8 jars or the release workflow) and the release tag, for examplejenkins-2.580.1; - how to reproduce it, and what an attacker gains.
We answer within two business days, agree on a fix and a disclosure date with you, and credit you in the release notes unless you prefer not to be named.
Agent8 repackages the Jenkins agent (remoting) for older Java. A vulnerability in remoting itself is fixed upstream by the Jenkins project: report it to them (https://www.jenkins.io/security/), and Agent8 ships the fix in a new release once the controller's remoting version includes it. Problems specific to Agent8, such as the downgrade, the run-time Java agent, install.sh downloads and checksum checks, or the release process, belong here.
Agent8 is supported until at least 31 December 2031. Security updates are free, for everyone.
Fixes ship in a new release for each supported Jenkins version; rerun install.sh to get one. When a fix ships we publish a GitHub security advisory saying who is affected and what to do.
Every release carries sha256sums.txt. Releases published from 17 October 2026 on also carry a CycloneDX SBOM per jar (agent8-javaN.cdx.json) and signed build-provenance and SBOM attestations; earlier releases have only the checksums until they are re-released. To check a jar came unmodified from this repository's release workflow:
gh attestation verify agent8-java8.jar --repo keelinfra/agent8keelinfra sells services for Agent8, so we treat ourselves as its manufacturer under the CRA (Regulation (EU) 2024/2847). Agent8 is a default-class product (not listed in Annex III). Actively exploited vulnerabilities are reported through ENISA's Single Reporting Platform within 24 hours, as the CRA requires since 11 September 2026; vulnerabilities in remoting are reported to the Jenkins project. How we read the CRA is on keelinfra.io/security.
