Security readout for executives and security teams
Plain-English summary
A vulnerable WordPress pricing-table plugin can echo a hostile email parameter back into a visitor’s browser. If a user is tricked into opening a crafted link, script may run in that user’s session. The issue is medium severity because it needs user interaction and the cited impact is limited confidentiality and integrity loss.
Executive priority
Treat as a moderate website risk. Prioritize internet-facing WordPress sites using this plugin, especially where administrator or customer sessions may be exposed to malicious links.
Technical view
Plugmatter Pricing Table Lite through version 1.0.32 has reflected cross-site scripting in license.php via the email parameter. CVSS 3.1 is 6.1: network reachable, low complexity, no privileges required, user interaction required, changed scope, low confidentiality and integrity impact, and no availability impact.
Likely exposure
Exposure is limited to WordPress sites running Plugmatter Pricing Table Lite version 1.0.32 or earlier. The source bundle does not identify other products or a fixed version.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. Practical abuse requires getting a target user to interact with attacker-controlled content that reaches the vulnerable parameter.
Researcher notes
Evidence supports CWE-79 reflected XSS in license.php through the email parameter. The record identifies versions up to and including 1.0.32 as vulnerable. No exploit-in-the-wild evidence, fixed version, or vendor patch details are present in the supplied bundle.
Mitigation direction
- Inventory WordPress sites for Plugmatter Pricing Table Lite installations.
- Identify any installations at version 1.0.32 or earlier.
- Check Wordfence and vendor guidance for a fixed release or official remediation.
- Disable or remove the plugin where it is not business-critical.
- Apply compensating controls for suspicious requests to license.php.
Validation and detection
- Confirm plugin presence and version from WordPress administrative inventory.
- Review web logs for license.php requests containing unusual email parameter content.
- Check whether the plugin remains enabled on public-facing sites.
- Verify remediation guidance before assuming an update fully resolves the issue.

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.
