CVE-2026-93883 pluginsware CVE debrief

Who should care

Defenders responsible for WordPress sites using the Advanced Classifieds & Directory Pro plugin should assess exposure and prioritize verification of their sites' configurations and plugin versions.

Why it matters

CVE-2026-93883 is a Stored Cross-Site Scripting vulnerability in the Advanced Classifieds & Directory Pro plugin for WordPress. It allows authenticated attackers with custom-level access to inject arbitrary web scripts via the 'phone' parameter, which can execute on page access. This vulnerability requires specific conditions to be met, including the 'Force Bootstrap' setting being enabled and the 'ACADP Listing Address' widget being used on single listing pages. Defenders should verify their sites' exposure, prioritize patching or mitigating the vulnerability, and monitor for suspicious activity.

• Defenders need to verify if their sites are using version 3.4.4 or lower of the plugin and have the conditions for exploitation met.
• Sites with the 'Force Bootstrap' setting enabled and the 'ACADP Listing Address' widget on single listing pages are potentially vulnerable.
• Successful exploitation could allow authenticated attackers to inject malicious scripts, potentially leading to user interactions with injected content.
• Defenders should prioritize updating to a patched version of the plugin if available and consider compensating controls like limiting plugin functionality or closely monitoring site activity.

Technical summary

The Advanced Classifieds & Directory Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'phone' parameter in all versions up to, and including, 3.4.4. This is due to insufficient input sanitization and output escaping. An attacker with custom-level access and above can inject arbitrary web scripts that will execute when a user accesses an injected page. This vulnerability is only exploitable if the 'Force Bootstrap' setting is enabled and the 'ACADP Listing Address' widget is used on single listing pages.

Defensive priority

Defenders should prioritize verifying if their sites use the affected plugin version and have the 'Force Bootstrap' setting enabled, and assess exposure based on the presence of the 'ACADP Listing Address' widget on single listing pages.

Recommended defensive actions

• Verify if the Advanced Classifieds & Directory Pro plugin version is 3.4.4 or lower and update to a patched version if available.
• Check if the 'Force Bootstrap' miscellaneous setting is enabled and consider disabling it if not necessary.
• Assess the presence of the 'ACADP Listing Address' widget on single listing pages and consider removing it if not necessary.
• Monitor for any suspicious activity related to the plugin and the 'phone' parameter.
• Perform a thorough review of the plugin's configuration and usage to identify potential vulnerabilities.
• Implement additional security measures such as Web Application Firewall (WAF) rules to detect and prevent exploitation.
• Keep records of the verification and mitigation efforts for future reference and auditing purposes.
