Security Advisories » Jenkins Security Advisory 2018-10-29
This advisory announces vulnerabilities in the following Jenkins deliverables:
The Groovy Sandbox library used by Script Security Plugin and Pipeline Groovy Plugin did not apply sandbox restrictions to finalize methods. This could be used to invoke arbitrary constructors and methods, bypassing sandbox protection.

These versions include fixes to the vulnerabilities described above. All prior versions are considered to be affected by these vulnerabilities unless otherwise indicated.
The Jenkins project would like to thank the reporters for discovering and reporting these vulnerabilities:
