Summary
RCE vulnerability in SCM Filter Jervis Plugin
Details

SCM Filter Jervis Plugin 0.2.1 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to configure jobs with the filter, or control the contents of a previously configured job’s SCM repository.

SCM Filter Jervis Plugin 0.3 configures its YAML parser to only instantiate safe types.

Severity
8.8 (High)
CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
