CVE-2026-10531 AI Share & Summarize CVE debrief

Who should care

Users of the AI Share & Summarize WordPress plugin, particularly those with the Contributor role and above, should be aware of this vulnerability and take steps to mitigate it. Additionally, WordPress administrators and security teams should prioritize updating the plugin to version 2.0.4 or later to prevent exploitation.

Technical summary

The AI Share & Summarize WordPress plugin before 2.0.4 does not properly sanitize and escape some of its shortcode attributes, allowing users with the Contributor role and above to perform Stored Cross-Site Scripting attacks. The vulnerability is due to insufficient input validation and sanitization of user-supplied data. An attacker could exploit this vulnerability by injecting malicious code into the plugin's shortcode attributes, which would then be executed by the plugin, potentially leading to unauthorized access or data theft.

Defensive priority

High priority should be given to updating the AI Share & Summarize WordPress plugin to version 2.0.4 or later. Additionally, users with the Contributor role and above should be educated on the risks of Stored Cross-Site Scripting attacks and the importance of proper input validation and sanitization.

Recommended defensive actions

• Update the AI Share & Summarize WordPress plugin to version 2.0.4 or later.
• Educate users with the Contributor role and above on the risks of Stored Cross-Site Scripting attacks.
• Implement additional security measures, such as input validation and sanitization, to prevent similar vulnerabilities.
• Monitor the plugin's shortcode attributes for suspicious activity.
• Consider implementing a Web Application Firewall (WAF) to detect and prevent exploitation attempts.
