CVSS 3.1
9.6 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:HCVE-2023-27898
Critical (9.6) in jenkins jenkins. EPSS 1.8% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.main:jenkins-core 2.375.4, 2.394.
Jenkins 2.270 through 2.393 (both inclusive), LTS 2.277.1 through 2.375.3 (both inclusive) does not escape the Jenkins version a plugin depends on when rendering the error message stating its incompatibility with the current version of Jenkins, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to provide plugins to the configured update sites and have this message shown by Jenkins instances.
