MITRE ATT&CK
2 techniques across 2 tactics: Defense Evasion, Initial Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires (1) an authenticated WordPress account on the target site - the description states 'any authenticated user,' and on typical WordPress sites the lowest self-service subscriber role suffices; and (2) the site must actually use WP Events Manager's paid-event registration/ticketing feature, since the flaw lies in the price computation for paid bookings. The concrete trigger is submitting an attacker-controlled 'quantity' value during paid-event registration that the plugin fails to validate before computing price. Limiting factors: it cannot be exploited without any authentication (contradicting the PR:N in the published CVSS vector), and it has no effect on sites that offer only free events or do not use this plugin's payment workflow. |
| Impact | The published CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:H) appears inflated and internally inconsistent with the description: the description explicitly states 'any authenticated user,' which implies PR:L, not the PR:N encoded in the vector - verify with the vendor/WPScan. Likewise, the impact is a fraudulent paid booking (an integrity violation of the plugin's commercial records), not a confidentiality or availability breach, so C:H and A:H are not well supported. Real-world risk signals point lower than the headline score: EPSS is only 0.13% (3rd percentile), the CVE is NOT on CISA KEV, and there is no evidence of active exploitation. That said, publicly available exploit code exists and exploitation is trivial (low complexity, self-registration common on WordPress), so for any site actually selling paid tickets through this plugin the practical fraud risk is meaningful and should be prioritized. For sites not using the paid-event feature, the effective risk is minimal. |
| Exploit ScenarioDerived | An attacker registers a normal WordPress account (self-registration is commonly enabled) on a site running WP Events Manager, then begins checkout for a paid event and tampers with the submitted quantity parameter so the plugin computes a zero or non-positive price. The booking is recorded as completed and paid, granting the attacker a valid ticket/registration without any charge. Because exploit code is publicly available and complexity is low, this can be repeated at scale to defraud the event organizer. |

Alert meAnalysisAIv1 – Aug 07, 2026
Payment bypass in the WP Events Manager WordPress plugin before 2.2.5 lets any authenticated user register for a paid event and receive a fully completed booking without paying, because the plugin trusts an attacker-controlled quantity value and derives the charge from it. WPScan reports publicly available exploit code exists, though there is no evidence of active exploitation and the EPSS score is very low (0.13%, 3rd percentile). The flaw is a business-logic/authorization defect rather than a memory-safety issue, so impact is financial fraud against event organizers rather than server compromise.
RemediationAI
Vendor-released patch: 2.2.5 - upgrade the WP Events Manager plugin to version 2.2.5 or later, which is the primary and complete fix. If immediate patching is not possible, apply compensating controls tailored to the paid-event flow: disable or unpublish paid events until the update is applied (trade-off: halts legitimate ticket sales); reconcile recent completed bookings against actual payment-gateway settlement records to detect and void fraudulent zero/underpaid registrations (trade-off: manual effort, does not prevent new fraud); and restrict new account self-registration or require manual approval to reduce the pool of authenticated attackers (trade-off: added friction for genuine customers). Consult the WPScan advisory (https://wpscan.com/vulnerability/084705cc-eb47-4e5f-9e7a-1bc0d6b218a4/) for exploit specifics before validating fixes.

Technical ContextAI · show details
The affected component is WP Events Manager, a WordPress plugin that adds event listing, ticketing, and paid-registration workflows to a WordPress site. The root cause maps to CWE-287 (Improper Authentication) as tagged, but functionally it is a server-side trust failure: the booking/checkout routine computes the amount owed directly from a client-supplied 'quantity' parameter without server-side validation or re-verification against expected pricing. By manipulating that quantity (for example to a zero, negative, or otherwise degenerate value that yields a non-positive computed price), an attacker forces the plugin to mark the booking as paid/completed. The CPE cpe:2.3:a:unknown:wp_events_manager identifies the affected software; the vendor is listed as 'unknown' in the CPE dictionary, so authoritative vendor attribution should be confirmed via the WordPress plugin directory.

Lifecycle Timeline

The WP Events Manager WordPress plugin before 2.2.5 does not validate the requested quantity when registering for a paid event and computes the price from the attacker-controlled quantity, allowing any authenticated user to create a completed booking for a paid event without making a payment.

Executive ViewAI
WP Events Manager plugin (versions before 2.2.5) allows authenticated users to bypass payment for event registrations, creating direct revenue loss for affected organizations. Publicly available exploit code exists for this vulnerability. All organizations using this plugin face immediate financial fraud risk and should patch immediately.
Apply vendor patch: WP Events Manager version 2.2.5 or later.
