Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Beaver Builder Beaver Builder beaver-builder-lite-version allows Stored XSS.This issue affects Beaver Builder: from n/a through <= 2.8.4.3.
A Beaver Builder WordPress plugin vulnerability allows stored cross-site scripting in versions through 2.8.4.3. An authenticated low-privilege user could place script content that later runs when another user views it. That can expose data, alter page behavior, or affect administrator trust in the site.
Executive priority
Treat as a near-term WordPress hygiene fix, not a crisis. Prioritize public sites, sites with many contributors, and environments where administrator sessions are frequent. The main business concern is trust and content integrity, not confirmed widespread exploitation.
Technical view
CVE-2024-53797 is CWE-79 stored XSS in Beaver Builder beaver-builder-lite-version through 2.8.4.3. CVSS 3.1 is 6.5, with network access, low attack complexity, low privileges required, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress sites running Beaver Builder or beaver-builder-lite-version at version 2.8.4.3 or earlier. Risk is higher where untrusted or many lower-privilege users can create or edit content handled by the plugin.
Exploitation context
The source bundle does not show CISA KEV listing or other cited evidence of active exploitation. The CVSS vector indicates exploitation requires low privileges and user interaction, consistent with stored XSS that affects a later viewer.
Researcher notes
Evidence is limited to the CVE record, CVE List data, and Patchstack reference. The bundle does not provide a vulnerable parameter, proof of concept, fixed version, or exploitation telemetry. Avoid asserting more specific exploitability without vendor details.
Mitigation direction
Inventory WordPress sites using Beaver Builder or beaver-builder-lite-version.
Compare installed versions against the affected range through 2.8.4.3.
Check Beaver Builder, WordPress, or Patchstack guidance for the fixed version.
Upgrade if vendor guidance confirms a patched release is available.
Limit plugin/content editing access to trusted users until remediated.
Validation and detection
Confirm plugin name and version from each WordPress installation.
Verify no site remains on Beaver Builder version 2.8.4.3 or earlier.
Review low-privilege accounts with content or plugin editing access.
Check recent content changes for unexpected script-bearing entries.
Document remediation status and any vendor guidance followed.

Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
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.
