# CVE-2026-75961: NEX-Forms \<= 9.3.0 - Authenticated (Administrator+) SQL Injection via 'operator' Key of the 'additional\_params' Parameter

- Severity: CVSS 4.9 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-09-18 · Updated: 2026-09-19

## Affected

- webaways NEX-Forms – Ultimate Forms Plugin for WordPress: through 9.3.0

## Description

The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to generic SQL Injection via the 'additional_params' parameter in all versions up to, and including, 9.3.0 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 custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The operator allowlist applied by get_table_records() when building its own WHERE fragment is not enforced on the same tainted additional_params array when it is forwarded to get_total_records(), leaving the SQL sink unprotected.
