Vulnerability from cvelistv5
Published

Modified
2026-08-27 17:39
Severity ?
7.1 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N
CWE
  • CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes
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.
