Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Kyle Phillips Nested Pages wp-nested-pages allows Stored XSS.This issue affects Nested Pages: from n/a through <= 3.2.9.
Security readout for executives and security teams
Plain-English summary
CVE-2025-24579 is a stored cross-site scripting issue in the WordPress Nested Pages plugin up to version 3.2.9. A highly privileged user could store unsafe script content that later runs in another user’s browser. Business urgency is moderate because exploitation requires elevated access and user interaction, but affected WordPress sites should still be reviewed.
Executive priority
Prioritize this in the next WordPress maintenance cycle, sooner for externally managed or multi-admin sites. It is not described as actively exploited, but stored XSS can support account abuse, content manipulation, and trust damage if privileged access is misused.
Technical view
The issue is CWE-79 improper input neutralization during web page generation in Kyle Phillips Nested Pages wp-nested-pages. CVSS 3.1 is 5.9: network reachable, low complexity, high privileges required, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress installations using Nested Pages through version 3.2.9. Sites without the plugin, or not within the affected version range, are not indicated as exposed by the supplied sources.
Exploitation context
The supplied sources do not show CISA KEV listing or active exploitation evidence. The CVSS vector indicates an attacker needs high privileges and a victim action, so this is more likely to matter after account compromise or misuse by trusted users.
Researcher notes
The source bundle names the vulnerability class, affected plugin, version ceiling, CVSS vector, CWE-79, and Patchstack reference. It does not provide exploit details, a confirmed fixed version, or operational indicators, so validation should focus on version inventory and vendor guidance.
Mitigation direction
Inventory WordPress sites for the Nested Pages plugin and version.
Check vendor or Patchstack guidance for fixed release or official remediation.
Restrict high-privileged WordPress access to trusted, necessary users only.
Disable or remove the plugin where it is not operationally required.
Review recent privileged content changes for unexpected script-like content.
Validation and detection
Confirm whether wp-nested-pages is installed on each WordPress site.
Record installed versions and flag versions through 3.2.9.
Review roles able to create or modify Nested Pages content.
Check audit logs for unusual privileged page or plugin activity.
After remediation, verify affected versions are no longer present.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
