Jenkins Email Extension Plugin: Attackers able to control email content may specify `file:` URLs for images to read arbitrary files from Jenkins controller filesystem
Details
Jenkins Email Extension Plugin 1933.v45cec755423f and earlier includes a feature that allows inlining images as `base64` in email content by setting the `data-inline` attribute. No restrictions are placed on the image URLs that can be inlined.
This allows attackers able to control the email content to specify `file:` URLs for images to read arbitrary files from the Jenkins controller filesystem.
The feature allowing inlining images as `base64` in email content by setting the `data-inline` attribute is removed from Email Extension Plugin 1933.1935.v276319e3cc47.
