Security readout for executives and security teams
Plain-English summary
EventPrime, a WordPress event calendar plugin, has a broken access control issue through version 4.2.8.0. An unauthenticated remote user may access limited information that should require authorization. The available sources rate this as medium severity, focused on confidentiality rather than site takeover.
Executive priority
Treat as a near-term WordPress hygiene item, not an emergency based on current evidence. Prioritize public-facing sites and any site where event data exposure would create privacy, reputational, or compliance concerns.
Technical view
CVE-2026-24380 is a CWE-862 Missing Authorization flaw in Metagauss EventPrime eventprime-event-calendar-management. CVSS 3.1 is 5.3: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. Sources identify affected versions as through <= 4.2.8.0, with low confidentiality impact and no stated integrity or availability impact.
Likely exposure
Exposure is most likely on internet-facing WordPress sites running EventPrime version 4.2.8.0 or earlier. The issue requires no authentication or user interaction, so public sites using the plugin should be inventoried promptly.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not listed as KEV. No exploit details or public weaponization status are provided in the source bundle. Risk comes from unauthenticated network reachability and weak authorization checks.
Researcher notes
Evidence is limited to the CVE record and Patchstack entry. The vulnerability is described only as broken access control/missing authorization, with confidentiality impact. No affected endpoint, fixed version, exploit status, or detailed remediation is included in the supplied sources.
Mitigation direction
- Inventory WordPress sites for the EventPrime plugin and installed version.
- Check Metagauss and Patchstack guidance for a fixed release or official mitigation.
- Upgrade EventPrime if a vendor-supported fixed version is available.
- If no fix is available, assess whether temporarily disabling the plugin is acceptable.
- Monitor WordPress and web logs for unusual unauthenticated EventPrime access patterns.
Validation and detection
- Confirm whether EventPrime is installed on each WordPress site.
- Verify whether the installed version is 4.2.8.0 or earlier.
- Review vendor or Patchstack advisory status for fixed-version details.
- Validate remediation in staging before production rollout.
- Document sites where the plugin remains enabled without a confirmed fix.
