Security readout for executives and security teams
Plain-English summary
This vulnerability affects WordPress sites using Classy Addons for Elementor through version 1.2.7. It can allow script execution in a user’s browser, potentially exposing data or enabling limited site actions. The issue is medium severity and needs attention where the plugin is installed, especially on business-critical WordPress properties.
Executive priority
Treat this as a moderate-priority WordPress hygiene issue. It is not confirmed as actively exploited, but affected public sites should be inventoried and remediated promptly because XSS can support account abuse and data exposure.
Technical view
CVE-2024-50553 is a DOM-based cross-site scripting flaw caused by improper input neutralization during page generation. CVSS 3.1 is 6.5 with network access, low attack complexity, low privileges, required user interaction, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress installations running Classy Addons for Elementor version 1.2.7 or earlier. Sites without this plugin are not indicated as affected by the provided sources.
Exploitation context
The CVE is not listed as KEV, and the provided sources do not state active exploitation. The CVSS vector indicates exploitation requires low privileges and user interaction, but no exploit details or observed campaign evidence are provided.
Researcher notes
The source evidence identifies DOM-based XSS in Classy Addons for Elementor through 1.2.7 and provides CVSS details. It does not include proof-of-concept material, confirmed exploitation, or a named fixed version in the supplied bundle.
Mitigation direction
- Identify whether Classy Addons for Elementor is installed and enabled.
- Check vendor or Patchstack guidance for a fixed or recommended version.
- Update the plugin if an official safe version is available.
- Disable or remove the plugin if it is unnecessary or cannot be safely updated.
- Limit WordPress account privileges until remediation is complete.
Validation and detection
- Confirm the installed plugin version on every WordPress site.
- Flag any instance running version 1.2.7 or earlier.
- Verify remediation against vendor or Patchstack guidance.
- Review WordPress logs for suspicious activity around affected pages.
- Confirm no unneeded privileged accounts remain active.
