CVE-2026-77144
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk22th percentile - higher than 22% of all known CVEs
Summary
The frontend management plugin attributed a newly created event to the submitting user's organizer record only when the request supplied no organizer of its own. The accompanying permission check confirmed only that the submitting user held any organizer role. A user with frontend event management access could therefore create an event that is attributed to another organizer.
Risk Assessment
A user could create events attributed to other organizers, potentially leading to unauthorized actions or incorrect attributions.
Recommendation
Update the plugin to a version where event attribution and permission checks are fixed. Additionally, verify user permissions before granting event management access.
Other vulnerabilities in Extension
See all- CVE-2026-77146High
The extension's invitation controller fails to stop processing after redirecting on invalid input (missing hash, non-existent, disabled, or deleted users), allowing an unauthenticated attacker to set a new password for and re-enable an arbitrary existing frontend user account. This vulnerability is only present in the 8.x versions of the extension.
- CVE-2026-77145High
The permission check for the frontend management update flow verified a different event than the one the request went on to modify. A user with frontend event management access could therefore modify events belonging to other organizers.
