Security readout for executives and security teams
Plain-English summary
CVE-2025-48154 is a reflected cross-site scripting issue in the WordPress Multimedia Playlist Slider Addon for WPBakery Page Builder, affecting versions through 2.1. A successful attack could make a user’s browser run attacker-controlled script after user interaction, potentially exposing data or changing page content in that user’s session.
Executive priority
Prioritize this for internet-facing WordPress sites using the affected plugin, especially marketing or customer-facing sites. It is high severity, but urgency depends on confirmed plugin presence and whether vendor remediation exists.
Technical view
The issue is CWE-79 improper neutralization during web page generation in package lbg_vp_youtube_vimeo_addon_visual_composer. The CVSS 3.1 score is 7.1 high, with network access, low complexity, no privileges, required user interaction, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites that have the LambertGroup Multimedia Playlist Slider Addon for WPBakery Page Builder installed and running at version 2.1 or earlier. The source bundle does not establish exposure for sites without that plugin.
Exploitation context
The supplied sources describe reflected XSS and user interaction requirements. They do not state active exploitation, and the CVE is not marked as CISA KEV in the provided bundle. Treat exploit status as unconfirmed from these sources.
Researcher notes
Evidence is limited to the CVE record and Patchstack entry named in the source bundle. The bundle identifies reflected XSS, affected versions through 2.1, CVSS 7.1, and no KEV listing. It does not provide a fixed version, exploit details, or proof of active exploitation.
Mitigation direction
- Inventory WordPress sites for the affected plugin and version.
- Check Patchstack and vendor guidance for a fixed release or official mitigation.
- Update the plugin if a fixed vendor-supported version is available.
- Disable or remove the plugin where no trusted fix is available.
- Review WAF or WordPress security controls as compensating protection.
Validation and detection
- Confirm whether lbg_vp_youtube_vimeo_addon_visual_composer is installed on each WordPress site.
- Record installed plugin versions and flag versions 2.1 or earlier.
- Review public pages using the plugin for exposure to untrusted input paths.
- Check logs and security tooling for XSS indicators involving the plugin.
- Verify remediation by confirming plugin removal, disablement, or vendor-supported update.
