CVE-2026-117621

Jenkins versions 2.587 and earlier (LTS 2.580.1 and earlier ) are vulnerable to a cross-site scripting (XSS) vulnerability. The root cause is that the agent computes the URL for links displayed in the workspace browser for every file and directory. This flaw allows attackers who have control of a...

XSS vulnerability in workspace browser

When the workspace of a job is located on an agent, Jenkins retrieves the list of files and directories shown in the workspace browser from that agent. In Jenkins 2.587 and earlier, LTS 2.580.1 and earlier, the agent computes the URL of the link shown for each file and directory. This results in ...

Jenkins security vulnerabilities

Security vulnerabilities exist in Jenkins versions 2.587 and earlier, as well as 2.580.1 and earlier. These vulnerabilities arise from the fact that the agent calculates URLs for links displayed in the workspace browser for each file and directory; this may allow attackers controlling the agent...

Workspace temporary directories accessible through directory browser

Jenkins uses temporary directories adjacent to workspace directories, usually with the @tmp name suffix, to store temporary files related to the build. In pipelines, these temporary directories are adjacent to the current working directory when operating in a subdirectory of the automatically...

GHSA-QXP6-27GW-99CJ Time-of-check Time-of-use (TOCTOU) Race Condition in Jenkins

Due to a time-of-check to time-of-use TOCTOU race condition, the file browser for workspaces, archived artifacts, and $JENKINSHOME/userContent/ follows symbolic links to locations outside the directory being browsed in Jenkins 2.275 and LTS 2.263.2. This allows attackers with Job/Workspace...
