CVSS 3.1
4.3 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:NCVE-2025-27625
Medium (4.3) in jenkins jenkins. EPSS 0.6% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.main:jenkins-core 2.492.2, 2.500.
In Jenkins 2.499 and earlier, LTS 2.492.1 and earlier, redirects starting with backslash (`\`) characters are considered safe, allowing attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site, because browsers interpret these characters as part of scheme-relative redirects.
