CVE-2026-76909 · Unleash: CR-approval email renders user-controlled raw HTML
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Unleash is an open-source feature management platform. Prior to 8.0.3, the change-request approval email template at src/mailtemplates/requested-cr-approval/requested-cr-approval.html.mustache renders the user-controlled changeRequestTitle, requesterName, and requesterEmail values without HTML escaping, and sendRequestedCRApprovalEmail passes those values to Mustache rendering. A project member who can create a change request when approval emails are enabled can inject HTML into an approver's notification, allowing forged links, tracking content, or visually altered email content. This issue is fixed in version 8.0.3.
