Smart Popup By Supsystic
Monthly
Privilege escalation in the Smart Popup by Supsystic WordPress plugin (all versions through 1.12.0) enables unauthenticated remote attackers to create persistent WordPress Administrator accounts with attacker-controlled credentials. Three compounding flaws are chained: a PHP `array_merge()` collision silently removes the `save` action from the popup module's permission blocklist, the subscription confirmation email leaks a reusable `pps_nonce` that the `wp_ajax_nopriv_save` endpoint accepts, and `createWpSubscriber()` applies no server-side role allowlist - allowing an attacker to freely set `params[tpl][sub_wp_create_user_role]=administrator`. No public exploit or CISA KEV listing is confirmed at time of analysis, but the attack chain is fully described in the CVE and the low complexity makes independent weaponization likely.
Authenticated attackers holding a WordPress administrator account can store an encoded template-injection payload in a Smart Popup by Supsystic text block, which the plugin's template engine later evaluates server-side, allowing PHP constants such as database credentials and authentication keys to be read. Only sites running the plugin before version 2.0.2 are affected. Exploitation requires high privileges (PR:H) with no victim interaction, which confines realistic exposure to trusted or insider administrators or a hijacked admin session; the vulnerability is not in CISA KEV, and the available WPScan reference is a public PoC reference that is not verified as working exploit code. The vendor has released a fix, and the priority label is this_month.
SQL injection in the 'sidx' parameter of the Smart Popup by Supsystic WordPress plugin (all versions up to and including 1.13.2) lets authenticated attackers with administrator-level privileges append arbitrary SQL statements to existing queries and extract sensitive data from the site's database. The CVSS vector confirms high privileges are required (PR:H) and impact is limited to confidentiality (C:H/I:N/A:N), and no public exploit or CISA KEV entry has been recorded - no public exploit identified at time of analysis - so despite a CVSS base score of 4.9 this is a low real-world-priority issue because an attacker must already hold the broad database and site access that administrators legitimately possess. Affected deployments are those running 1.13.2 or earlier; the vendor released 1.13.3 to remediate it.
