A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: >= 3.0.0, < 3.1.31
Patched in 3.1.31
Vulnerable: < 2.2.23
Patched in 2.2.23
Details
The control panel action formie/sent-notifications/get-resend-modal-content (SentNotificationsController::actionGetResendModalContent) performed only requireAcceptsJson() and loaded a SentNotification by request id without permission or object-level authorization checks.
Any authenticated user who could invoke the action could enumerate notification IDs and read full email content — including recipient headers and the complete HTML body containing submitted form data (PII) — without formie-accessSentNotifications or equivalent permission. Sibling actions in the same controller enforced authorization.
Fixed in 3.1.31 (Craft 5) and 2.2.23 (Craft 4).
Craft 5: canView() is enforced after loading, consistent with actionEdit.
Craft 4: formie-viewSentNotifications permission is required.
Restrict CP access to trusted users only until upgraded. No configuration workaround.
EPSS, exploit probability
Low0.41%
estimated chance of real-world exploitation in the next 30 days, higher than 36.1% of every CVE FIRST.org scores
Refreshed 11/8/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
