CVE-2026-77145
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
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.
Risk Assessment
A user with event management permissions could modify events belonging to other organizers, potentially leading to unauthorized changes or data integrity issues.
Recommendation
Update the extension to a version where the permission check is fixed. Additionally, review access logs to detect unauthorized changes.
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-2026-77144High
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.
