CVE-2026-93661: Events Manager < 7.4.5 - Contributor+ Arbitrary Ticket Overwrite via IDOR

Noroxi assessment

Priority: Monitor (action score 10/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Unknown Events Manager 7.4.5.

Low priority for now. Upgrade to Unknown Events Manager 7.4.5 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The Events Manager WordPress plugin before 7.4.5 does not stop a ticket-update request from replacing the identifiers of the ticket it was authorized against, letting a user who can manage one event's tickets overwrite and reassign any ticket on the site to their own event.
