Security readout for executives and security teams
Plain-English summary
CVE-2026-25312 is a payment bypass issue in the WordPress EventPrime plugin through version 4.2.8.3. An unauthenticated attacker could potentially complete event-related transactions without proper payment authorization, creating revenue loss or fraudulent registrations. Public sources do not state active exploitation or name a fixed version.
Executive priority
Treat this as a high-priority revenue-integrity issue for any site selling paid events through EventPrime. It does not appear to be a server takeover issue from the provided data, but it may enable unpaid registrations. Prioritize inventory, payment workflow review, and vendor update monitoring.
Technical view
The issue is described as missing authorization / incorrectly configured access control in Metagauss EventPrime, package eventprime-event-calendar-management. CVSS 3.1 is 7.5 high: network exploitable, low complexity, no privileges, no user interaction, with high integrity impact. Scope is unchanged; confidentiality and availability impacts are not indicated.
Likely exposure
Exposure is likely for WordPress sites using EventPrime eventprime-event-calendar-management at version 4.2.8.3 or earlier, especially where paid event bookings, registrations, or ticketing workflows are enabled. Sites not using this plugin are not affected based on the provided sources.
Exploitation context
The CVE and Patchstack entry describe a payment bypass caused by missing authorization. The source bundle shows KEV is false, and no cited source states active exploitation. The available public detail is limited and does not provide a confirmed exploit status or a vendor-fixed version.
Researcher notes
The record maps to CWE-862 and indicates unauthenticated network access with high integrity impact. Public details are sparse: affected range is stated through 4.2.8.3, but the bundle does not identify a patched version. Avoid assuming exploit availability; validate exposure through version and business workflow review.
Mitigation direction
- Inventory WordPress sites for the EventPrime plugin and record installed versions.
- Prioritize sites using paid event registration or ticketing features.
- Check Metagauss and Patchstack guidance for a fixed version or official mitigation.
- If no fix is available, consider disabling payment-dependent EventPrime workflows temporarily.
- Review recent EventPrime orders for suspicious unpaid or underpaid registrations.
Validation and detection
- Confirm whether eventprime-event-calendar-management is installed on each WordPress site.
- Verify whether the installed version is 4.2.8.3 or earlier.
- Check whether paid booking or payment workflows are enabled.
- Review web, application, and payment records for inconsistent booking/payment states.
- Monitor vendor advisories for updated remediation details.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
