Security readout for executives and security teams

Plain-English summary

This CVE is a reflected cross-site scripting issue in a WordPress radio player addon for WPBakery. A successful attack could make a victim’s browser run attacker-controlled script after user interaction, potentially affecting session data, page integrity, or user trust. The source bundle does not name a fixed version.

Executive priority

Handle as a high-priority WordPress exposure review, especially on public or revenue-facing sites. The issue is not confirmed exploited in the provided sources, but no named fixed version is included, so inventory and vendor-guidance checks should happen promptly.

Technical view

CVE-2025-53564 is CWE-79 reflected XSS in LambertGroup HTML5 Radio Player - WPBakery Page Builder Addon, package lbg_radio_player_addon_visual_composer, reported for versions through 2.5. CVSS 3.1 is 7.1 with network access, low complexity, no privileges, required user interaction, and changed scope.

Likely exposure

Exposure is likely limited to WordPress sites that have the LambertGroup HTML5 Radio Player - WPBakery Page Builder Addon installed at version 2.5 or earlier. The affected metadata in the bundle is sparse, so confirm against actual plugin inventory.

Exploitation context

The bundle supports reflected XSS risk but does not show active exploitation. KEV is false. Exploitation requires tricking a user into interacting with attacker-controlled input or a crafted link, and the source data does not provide exploit details.

Researcher notes

The key uncertainty is remediation status. The CVE description and Patchstack reference identify reflected XSS through 2.5, while the affected product metadata is limited. Avoid assuming broader LambertGroup products or unrelated WPBakery components are affected without vendor confirmation.

Mitigation direction

  • Inventory WordPress sites for lbg_radio_player_addon_visual_composer.
  • Check LambertGroup, Patchstack, or WordPress plugin guidance for a fixed release.
  • Disable or remove the addon where no supported fix is available.
  • Prioritize sites with authenticated users, editors, or customer-facing traffic.
  • Apply compensating controls only as temporary risk reduction.

Validation and detection

  • Confirm whether the addon is installed and record its version.
  • Treat version 2.5 or earlier as potentially affected.
  • Check Patchstack and vendor records for updated remediation status.
  • Review web logs for unusual requests after 2025-08-20.
  • Do not validate with live exploit payloads in production.
