CVE-2023-43494: Jenkins

Medium severity, CVSS 4.3. EPSS: 3.9% chance of exploitation in the next 30 days.

Jenkins 2.50 through 2.423 (both inclusive), LTS 2.60.1 through 2.414.1 (both inclusive) does not exclude sensitive build variables (e.g., password parameter values) from the search in the build history widget, allowing attackers with Item/Read permission to obtain values of sensitive variables used in builds by iteratively testing different characters until the correct sequence is discovered.

Affected products

• Jenkins Jenkins: from 2.50, before 2.424 (fixed in 2.424); from 2.60.1, before 2.414.2 (fixed in 2.414.2)
