Administrator SQL Injection in Popup box <= 6.0.1 versions.

AnalysisAI

SQL injection in the AYS Popup Box WordPress plugin (versions 6.0.1 and earlier) lets an authenticated administrator inject arbitrary SQL into the WordPress database through an unsanitized plugin parameter (CWE-89). Because exploitation requires existing high-privilege administrator access per the CVSS PR:H metric, this is primarily a data-exposure/privilege-abuse issue rather than a remote-takeover flaw, and no public exploit has been identified at time of analysis. It was reported by Patchstack rather than discovered in active attacks, and is not listed in CISA KEV.

Technical ContextAI

The affected component is Popup Box (vendor slug 'ays-popup-box'), a WordPress plugin by AYS Pro used to build on-site popups, modals, and lead-capture boxes. The root cause is CWE-89 (Improper Neutralization of Special Elements used in an SQL Command): one or more admin-side handlers concatenate attacker-controlled input directly into a SQL statement against the WordPress MySQL/MariaDB backend instead of using parameterized queries via $wpdb->prepare(). The CVSS scope-changed flag (S:C) reflects that injected SQL reaches the shared WordPress database, enabling impact beyond the plugin's own authorization boundary - for example reading wp_users, wp_usermeta, or secrets stored by other plugins. No CPE strings were supplied in the source data, so the affected configuration is derived from the Patchstack advisory and the version string '<= 6.0.1'.

RemediationAI

No vendor-released patch version is identified in the available data; the advisory only specifies the affected range '<= 6.0.1', which implies a fixed release exists but the exact patched version is not confirmed from the input. Update Popup Box to the latest available release from the wordpress.org plugin repository or the AYS Pro vendor site once a version greater than 6.0.1 is confirmed, and consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/ays-popup-box/vulnerability/wordpress-popup-box-plugin-6-0-1-sql-injection-vulnerability) for the fixed version. Because exploitation requires administrator access, the most effective compensating controls are tightening who holds the administrator role and enforcing strong authentication/MFA on admin accounts (trade-off: operational friction for legitimate admins), restricting wp-admin access by IP allowlist or VPN (trade-off: breaks remote administration from arbitrary networks), and deploying a WAF with SQLi rules covering the plugin's admin endpoints as a virtual patch until the upgrade is applied (trade-off: rule tuning needed to avoid breaking legitimate plugin queries). Review database query logs for anomalous statements originating from the plugin as a detection measure.
