CVE-2022-34171
Cross-site Scripting vulnerability in Jenkins
Impact
Since Jenkins 2.321 and LTS 2.332.1, the HTML output generated for new symbol-based SVG icons includes the `title` attribute of `l:ionicon` until Jenkins 2.334 and `alt` attribute of `l:icon` since Jenkins 2.335 without further escaping. This vulnerability is known to be exploitable by attackers with Job/Configure permission. Jenkins 2.356, LTS 2.332.4 and LTS 2.346.1 addresses this vulnerability, the `title` attribute of `l:ionicon` (Jenkins LTS 2.332.4) and `alt` attribute of `l:icon` (Jenkins 2.356 and LTS 2.346.1) are escaped in the generated HTML output.
