Security readout for executives and security teams
Plain-English summary
CVE-2025-31574 is a stored cross-site scripting issue in the WordPress Custom Content Scrollbar plugin through version 1.3. An authenticated attacker with low privileges may be able to store script content that runs when another user views an affected page. Business risk is moderate, mainly account/session abuse, content tampering, and trust impact.
Executive priority
Prioritize remediation in the normal vulnerability cycle, faster for public WordPress sites with many authenticated users. This is not marked as actively exploited, but stored XSS can undermine administrator trust, site integrity, and visitor safety if left unresolved.
Technical view
The CVE describes CWE-79 improper input neutralization during web page generation in SoftHopper Custom Content Scrollbar. CVSS 3.1 is 6.5: network attack, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress deployments running Custom Content Scrollbar version 1.3 or earlier. Sites without the plugin are not affected based on the provided sources. Risk is higher where authenticated low-privilege users can influence plugin-rendered content or settings viewed by other users.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The scoring indicates exploitation is network-accessible and low complexity, but requires low privileges and user interaction. Treat it as a realistic stored XSS risk, not as confirmed in-the-wild exploitation.
Researcher notes
Evidence is limited to CVE metadata and Patchstack’s vulnerability entry. The bundle identifies affected versions through 1.3 but does not provide exploit details, a patched version, or specific vulnerable parameters. Avoid assuming affected roles or payload behavior beyond the CVSS privileges and interaction requirements.
Mitigation direction
- Inventory WordPress sites for the Custom Content Scrollbar plugin.
- Check vendor, WordPress, or Patchstack guidance for a fixed version or advisory.
- Disable or remove the plugin if it is not business-critical.
- Restrict unnecessary authenticated access until remediation is complete.
- Monitor affected sites for unexpected script injection or content changes.
Validation and detection
- Confirm whether custom-content-scrollbar is installed on each WordPress site.
- Record installed plugin versions and flag version 1.3 or earlier.
- Review plugin-rendered pages and settings for unexpected stored script content.
- Verify remediation by confirming the vulnerable plugin version is absent.
- Check access logs for suspicious authenticated changes to plugin-managed content.
