CVE-2025-27625

MEDIUM

Jenkins < 2.492.2, < 2.500 - URL Redirection to Untrusted Site via Backslash Character Handling

Title source: llm
STIX 2.1

Description

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.
