- Access needed (per CVSS)
- Needs an admin-level account
- Range from
- CVE record (the advisory publisher) · score by CISA ADP
Details from the advisory
The Customer Engagement System WordPress plugin before 2.0.2 does not safely build the SQL statements that store a popup's page and category visibility rules, concatenating request-supplied ID values directly into an INSERT statement with no parameter binding or integer cast, allowing an authenticated administrator to inject arbitrary SQL and read the contents of the WordPress database.
medium 5.8 CVE-2026-115225 · published 2026-10-28
Server-side request forgery (SSRF) in Customer Engagement System (older than 2.0.2)

- Range from
- CVE record (the advisory publisher) · score by CISA ADP
Details from the advisory
The Customer Engagement System WordPress plugin before 2.0.2 does not restrict access to its MailChimp interest-group lookup or validate the API key supplied to it, allowing unauthenticated users to make the server open connections to arbitrary internal hosts and ports and infer from response timing which ones are reachable.
medium 4.9 CVE-2026-104023 · published 2026-10-10
SQL injection in Customer Engagement System (1.13.2 and older)
- Affected
- 1.13.2 and older
- Fixed in
- 1.13.3 *
- Access needed (per CVSS)
- Needs an admin-level account
- Range from
- CVE record (the advisory publisher) · score by Wordfence
Details from the advisory
The Smart Popup by Supsystic plugin for WordPress is vulnerable to generic SQL Injection via the 'sidx' parameter in all versions up to, and including, 1.13.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

high 8.8 CVE-2026-18322 · published 2026-08-05
Privilege escalation in Customer Engagement System (1.12.0 and older)
- Affected
- 1.12.0 and older
- Fixed in
- 1.13.0 *
- Access needed (per CVSS)
- Needs a low-level account (e.g. subscriber)
- Range from
- CVE record (the advisory publisher) · score by Wordfence
Details from the advisory
The Smart Popup by Supsystic plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.12.0. This is due to a permission map collision in the `havePermissions()` function in `classes/frame.php`, where `array_merge()` overwrites the popup module's administrator-restricted method list with the base controller's value, silently removing `save` from protected actions; this is compounded by the subscription confirmation email embedding the same generic `pps_nonce` that the unauthenticated `wp_ajax_nopriv_save` endpoint accepts, and by the complete absence of any server-side role allowlist in `createWpSubscriber()`. This makes it possible for unauthenticated attackers to submit a crafted POST request to `admin-ajax.php` using a nonce obtained from a public subscription confirmation email, setting `params[tpl][sub_wp_create_user_role]` to `administrator` via the exposed `popupControllerPps::save()` action, and then triggering the stored confirmation flow to create a persistent WordPress Administrator account with attacker-chosen credentials.
