Security readout for executives and security teams
Plain-English summary
Popup Builder 3.49 for WordPress can store attacker-supplied script in popup-related content. If an authenticated attacker can create or edit relevant content, the script may run later when popup selections are displayed, potentially stealing session data or changing page behavior.
Executive priority
Treat this as a moderate-priority website integrity risk. It is not unauthenticated remote code execution, but stored XSS can affect administrators or visitors and may support account compromise or reputational damage.
Technical view
The issue is persistent cross-site scripting in Popup Builder 3.49. The source bundle says attackers can break out of option tags through the post_title parameter, causing script execution when affected popup selection UI is rendered. CVSS 3.1 is 5.4, with low privileges required and user interaction required.
Likely exposure
Exposure appears limited to WordPress sites running Popup Builder version 3.49, especially where low-privileged authenticated users can submit or modify popup-related posts. The provided sources do not list other affected versions.
Exploitation context
The bundle includes an ExploitDB reference, so public exploit information exists. However, KEV status is false, and the supplied sources do not establish active exploitation in the wild.
Researcher notes
Evidence supports Popup Builder 3.49 only. The CVE metadata, VulnCheck advisory, and ExploitDB reference align on persistent XSS. Sources do not provide confirmed active exploitation, a named fixed version, or broader version range.
Mitigation direction
- Identify WordPress sites running Popup Builder version 3.49.
- Check the vendor and WordPress plugin pages for current remediation guidance.
- Upgrade to a vendor-supported fixed version if one is documented.
- Disable or remove Popup Builder where no supported fix is available.
- Limit content-editing privileges to trusted users until remediated.
Validation and detection
- Confirm installed Popup Builder versions across WordPress environments.
- Review whether untrusted users can create or edit popup-related content.
- Check affected content titles for suspicious script-like markup.
- After remediation, verify popup selection UI renders titles safely.
- Monitor WordPress audit logs for unusual authenticated content changes.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
