Trojanized plugin runs unauthenticated with full site privileges (AV:N/AC:L/PR:N/UI:N); 'full control' plus credential exfiltration justifies C:H/I:H/A:H, exceeding the input vector's C-only scoring.

AnalysisAI
Supply-chain compromise of three commercial WordPress plugins - Smart Post Show Pro (before 4.0.2), Real Testimonials Pro (before 3.2.5), and Product Slider for WooCommerce Pro (before 3.5.3) - shipped malicious code via the vendor's compromised update server, letting remote unauthenticated attackers deploy a second-stage payload that harvests credentials and other sensitive data and takes full control of affected sites. Publicly available exploit code exists and a patch is available from the vendor, but there is no public exploit identified as being used for active exploitation and the flaw is not in CISA KEV. EPSS is low (0.20%, 10th percentile), consistent with the malicious builds having been pulled once discovered rather than being mass-exploited in the wild.
Technical ContextAI
This is not a code-level defect in the plugins' own logic but a distribution/trust compromise: the affected products are premium WordPress plugins (PHP code running with full site privileges inside the WordPress runtime) that were tampered with upstream and delivered to site owners through the vendor's automatic update channel. Because a WordPress plugin executes on every request with access to the database, wp-config secrets, and admin sessions, embedded malicious code can act as a first-stage loader that fetches and runs a second-stage payload. No CWE was assigned by NVD, but the behavior maps to CWE-506 (Embedded Malicious Code) with an underlying CWE-494 (Download of Code Without Integrity Check) at the update-server trust boundary; the resulting activity (credential and data exfiltration) is why the record is tagged Information Disclosure. CPE strings reference the three plugin slugs under an 'unknown' vendor, and the EUVD entry pins the last-good versus first-fixed builds.
RemediationAI
Update immediately to the vendor-released patched builds - Smart Post Show Pro 4.0.2, Real Testimonials Pro 3.2.5, and Product Slider for WooCommerce Pro 3.5.3 - obtained directly from the vendor, per the WPScan advisory (https://wpscan.com/vulnerability/160ee7f7-91b6-4cce-9462-837130621402/). Because this was a supply-chain compromise rather than an exploitable code bug, patching alone is insufficient for sites that ran a tainted version: treat those installs as compromised, rotate all WordPress credentials, database passwords, API keys and secrets stored in wp-config, and invalidate active admin sessions and salts; audit for injected admin users, unknown scheduled tasks (WP-Cron), and unexpected outbound connections indicating a deployed second-stage payload. If you cannot immediately update, deactivate and remove the affected plugin (trade-off: loss of that plugin's site functionality) and restrict outbound network egress from the web host to break second-stage retrieval and exfiltration. Consider restoring from a known-clean backup predating the tainted update and re-scanning the filesystem for webshells before returning the site to service.
