AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Network-reachable read-only SQL injection requiring only subscriber authentication; AC:L because the injection mechanics are straightforward once the shortcode deployment precondition is satisfied.

The MPG - Multiple Page Generator, Bulk Landing Pages & Programmatic SEO plugin for WordPress is vulnerable to generic SQL Injection via URL Path in all versions up to, and including, 4.2.1 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 subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is only exploitable when the [mpg_spintax] shortcode is rendered in site-wide content such as a footer or template part, as the vulnerable code path is only reached when the shortcode is active on the requested page.
AnalysisAI
SQL injection in the MPG - Multiple Page Generator WordPress plugin (all versions through 4.2.1) allows authenticated attackers holding only subscriber-level accounts to append arbitrary SQL into existing database queries via a crafted URL path, enabling full exfiltration of the WordPress database including password hashes, user PII, and stored credentials. The flaw originates in SpintaxController.php and Helper.php where URL-path parameters are interpolated into queries without adequate escaping or use of WordPress's prepare() API; the code path is only reachable when the [mpg_spintax] shortcode is rendered in site-wide components such as footers or template parts. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Three specific conditions must all be true simultaneously: (1) The attacker holds a WordPress account at subscriber level or above - if public registration is disabled and no credentials can be obtained, exploitation is blocked at the PR:L requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, score 6.5) accurately characterizes a network-reachable, low-complexity exploit requiring a minimum-privilege authenticated session; the confidentiality-only impact (C:H/I:N/A:N) reflects that this is a read-path injection with no write or availability consequence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update the MPG plugin to a version beyond 4.2.1; the upstream fix is committed in WordPress plugin SVN changeset 3687328 (https://plugins.trac.wordpress.org/changeset?reponame=&old=3687328%40multiple-pages-generator-by-porthas&new=3687328%40multiple-pages-generator-by-porthas). … Detailed patch versions, workarounds, and compensating controls in full report. |
