Name of the Vulnerable Software and Affected Versions
Jenkins Email Extension Plugin versions prior to 1933.v45cec755423f
Description
The plugin allows inlining images as
base64 in email content by setting the data-inline attribute. Because there are no restrictions on the image URLs that can be inlined, attackers who can control the email content can specify file: URLs for images to read arbitrary files from the Jenkins controller filesystem.Recommendations
Update to a version later than 1933.v45cec755423f.
