The The WP Ultimate Review plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.4.2. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary shortcodes.

AnalysisAI
Authenticated shortcode injection in the WP Ultimate Review WordPress plugin (Roxnor) allows any user with subscriber-level access or higher to run arbitrary registered shortcodes on sites running version 2.4.2 or earlier. The attacker passes a crafted value to a plugin action that feeds it into do_shortcode() without validation (CWE-94), yielding high confidentiality and integrity impact per the assessed CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N (8.1). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated account with subscriber-level access or above on a WordPress site running WP Ultimate Review (by Roxnor) version 2.4.2 or earlier; sites allowing open user registration effectively lower this bar to near-unauthenticated. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine, moderately-high-priority issue but not an urgent widespread emergency. … 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 | No vendor-tagged patched release is confirmed in the supplied data; the references include a WordPress plugin Trac changeset (https://plugins.trac.wordpress.org/changeset?reponame=&old=3703958%40wp-ultimate-review&new=3703958%40wp-ultimate-review), so the status is best described as upstream fix available (changeset/commit) with a released patched version not independently confirmed - verify the current plugin version in the WordPress.org directory and update past 2.4.2 as soon as a fixed build is available, checking the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/dc0fe855-97b7-46ef-b1c8-1602447e97e6?source=cve) for the definitive fixed version. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every WordPress instance running WP Ultimate Review (Roxnor) at version 2.4.2 or earlier and restrict subscriber self-registration or disable open registration on any exposed site, since the subscriber-level prerequisite is the primary gate on exploitation; where the plugin is not business-critical, deactivate and remove it immediately. …
