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 a valid authenticated account with at least low privileges on the target WordPress site running Event Tickets version n/a through 5.30.2 (PR:L); remote and network-reachable with low complexity and no user interaction once authenticated. The exact feature, endpoint, or configuration that lacks the authorization check is not described in the available sources. Limiting factors: exploitation is impossible for fully unauthenticated attackers, and impact is confined to low integrity effects (C:N/I:L/A:N) - no data disclosure or denial of service. Sites that do not allow self-registration or that restrict low-privilege accounts further constrain exposure.

Impact

This is a moderate, not critical, priority. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, base 4.3) describes a network-reachable, low-complexity flaw that requires an already-authenticated low-privilege account (PR:L) and yields only a limited integrity impact (I:L) with no confidentiality or availability loss - consistent with a CWE-862 Missing Authorization / broken access control issue where a low-privileged user can perform an action they should not. The vuln.today decision label is 'this_month', signaling a scheduled-remediation rather than an emergency. There is no EPSS score, no CISA KEV listing, and no public exploit identified at time of analysis, so there is no current signal of active exploitation or mass scanning. The net picture is a real but bounded issue: exploitation is gated behind authentication and the damage is limited to low-integrity effects, so it ranks below internet-facing unauthenticated or code-execution flaws. Note that EPSS, KEV, SSVC automatable/technical-impact fields, and a confirmed fixed version are all absent from the input, so prioritization rests on the CVSS vector and the Patchstack report alone.

Exploit ScenarioDerived

An attacker who holds a low-privilege authenticated account on a WordPress site running Event Tickets (≤ 5.30.2) sends a crafted request to a plugin endpoint that fails to enforce proper authorization, allowing them to modify data or perform an action reserved for higher-privilege roles. The low attack complexity means no special timing or configuration is needed once the account exists, but the impact is limited to integrity (I:L). No public exploit identified at time of analysis; the trigger is not described in detail in the available sources.

AnalysisAIv1 – Oct 30, 2026

Event Tickets, the WordPress ticketing and event registration plugin maintained by Liquid Web / StellarWP, lacks an authorization check in at least one of its features through version 5.30.2, letting a logged-in low-privilege user perform an action that should require higher permissions and thereby alter site data (integrity impact only). The flaw is remote and low in complexity but requires a valid account, so sites that permit open self-registration or that host many subscriber-level users carry the most exposure; confidentiality and availability are unaffected. No public exploit code has been identified at time of analysis and the issue is not in CISA KEV, which keeps this a moderate, this-month priority rather than an emergency.

RemediationAI

No vendor-released patch version is identified in the available data for this issue; the only reference is the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/event-tickets/vulnerability/wordpress-event-tickets-plugin-5-30-2-broken-access-control-vulnerability-2, which should be monitored for the fixed release and applied as soon as one is published. Until a fix is confirmed, reduce the attack surface by closing self-registration and removing or downgrading unneeded low-privilege accounts on sites running Event Tickets - the trade-off is that legitimate community sign-ups and customer onboarding must be handled manually. If the plugin cannot be updated promptly, deactivating Event Tickets removes the vulnerable handlers entirely at the cost of losing event registration and ticketing functionality, and restricting the registration and account-management endpoints to trusted networks or to administrators via a WAF or security plugin limits reachability but may break front-end attendee workflows. Because exploitation requires only an authenticated low-privilege session, review recent changes to events, tickets, and attendee records for edits made by accounts that should not have had that capability.

Technical ContextAI · show details

The root cause is CWE-862 (Missing Authorization), a broken access control class in which a function or REST/AJAX handler performs a state-changing operation without verifying that the caller holds the capability the action requires - for example checking only that a user is logged in rather than calling current_user_can() with the appropriate role or nonce-protected capability. Event Tickets is a WordPress plugin, so the trust boundary is the WordPress user session: the CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) confirms a network-reachable endpoint that is exploitable with only low privileges and no user interaction, with the resulting impact limited to low integrity changes confined to the same security scope. The specific feature, endpoint, or configuration that omits the check is not described in the available sources, so the exact request flow an attacker would use is unverified from the supplied data. CPE cpe:2.3:a:liquid_web_/_stellarwp:event_tickets covers all versions up to and including 5.30.2 per the Patchstack disclosure.
