1 technique across 1 tactic: Privilege Escalation

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Requires an authenticated low-privilege account on a WordPress site with the Event Tickets plugin installed at version 5.30.2 or earlier (PR:L); no user interaction is needed (UI:N) and the vector is network-reachable (AV:N). Exploitation is limited to actions available through the specific plugin feature with the missing authorization check - the precise endpoint, parameter, or access-control level affected is not described in the available sources. Limiting factors for defenders: the attacker must first obtain a valid account on the target site, the impact is confined to limited confidentiality exposure (C:L, no integrity or availability impact), and sites not running the vulnerable plugin version are unaffected.

Impact

This is a moderate-severity issue (CVSS 4.3) whose signals point to a real but low-urgency problem rather than a critical emergency. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) indicates network-reachable, low-complexity exploitation requiring an existing low-privilege authenticated account (PR:L), with only limited confidentiality impact and no integrity or availability impact. The vuln.today priority is 'this_month' (not act_now/emergency), consistent with a meaningful-but-not-urgent finding. There is no CISA KEV listing (not confirmed actively exploited) and no EPSS score was provided in the input, so widespread automated exploitation cannot be inferred from the available data. No verified working exploit code is indicated - the sole reference is the Patchstack advisory entry. The practical risk is a low-privilege authenticated user (any registered WordPress account, depending on the endpoint) abusing missing authorization checks to reach data or actions they should not. Because this is an authorization flaw on a widely installed WordPress plugin, it is a legitimate patch-this-cycle item, but the authentication requirement and limited (confidentiality-only, Low) impact keep it well below the priority of an unauthenticated RCE.

Exploit ScenarioDerived

An attacker registers or already holds a low-privilege account on a WordPress site running Event Tickets (≤5.30.2) and sends a request to a plugin endpoint that fails to enforce proper authorization, returning or exposing event/ticket data belonging to other users or restricted contexts. No user interaction or high privileges are needed beyond the initial low-level authenticated session. No verified working exploit code is indicated in the provided data; only the Patchstack advisory is referenced.

AnalysisAIv1 – Oct 30, 2026

Missing authorization in the WordPress plugin Event Tickets (Liquid Web / StellarWP) through version 5.30.2 allows an authenticated low-privilege user to reach functionality that should sit behind a higher access-control level, resulting in limited information disclosure (CVSS 4.3, confidentiality-only, no integrity or availability impact). The attacker must already hold a valid account on a site running the affected plugin, and no user interaction is required. Neither CISA KEV listing nor public exploit code was identified at time of analysis, so the practical risk is a real but low-urgency access-control gap rather than an emergency; the Patchstack report is the only public reference supplied and it does not state a fixed version.

RemediationAI

No vendor-released patch version is listed in the available sources: the sole reference is the Patchstack record for Event Tickets through 5.30.2, which should be monitored (https://patchstack.com/database/wordpress/plugin/event-tickets/vulnerability/wordpress-event-tickets-plugin-5-30-2-broken-access-control-vulnerability?_s_id=cve) and the plugin's own update channel checked for a release above 5.30.2 before upgrading. Because exploitation requires an existing low-privilege account (PR:L), the effective interim controls are to tighten who can register and hold an account on the site - disable open WordPress user registration, remove or downgrade dormant subscriber-level accounts, and review any custom roles granted access to ticketing features - accepting that this restricts legitimate community/attendee logins. Where ticketing, RSVP or attendee data is not in active use, deactivating and deleting the Event Tickets plugin removes the exposure entirely, at the cost of losing those features and any stored ticket/attendee data. Restricting access to the WordPress admin and login surfaces to trusted networks or a WAF allowlist reduces the pool of accounts an attacker could obtain, but does not fix the underlying missing authorization check and adds operational friction for legitimate users.

Technical ContextAI · show details

Event Tickets is a WordPress ticketing and RSVP plugin maintained by StellarWP (Liquid Web), the same vendor family as The Events Calendar; it registers front-end and admin-side handlers, REST routes and AJAX actions that are expected to enforce capability checks before returning ticket, attendee or order-related data. The assigned CWE-862 (Missing Authorization) indicates that at least one of those code paths lacks a proper capability or nonce/authorization check, letting a logged-in user with minimal privileges invoke it. The supplied sources do not identify the specific endpoint, parameter, capability level or code path involved, so the trigger mechanism is not described in the available evidence; the CPE entry (cpe:2.3:a:liquid_web_/_stellarwp:event_tickets, all versions) confirms the affected component but not the granular vulnerable function. Because the CVSS vector is PR:L/UI:N with C:L only, any exploitation is confined to reading data already reachable through that one under-protected feature.
