Security readout for executives and security teams
Plain-English summary
A flaw in the WordPress Ultimate Addons for Beaver Builder Premium plugin may let an already authenticated low-privilege user gain higher privileges. If exploited, it could allow full confidentiality, integrity, and availability impact on an affected WordPress site.
Executive priority
Treat this as a high-priority WordPress plugin exposure if the affected premium plugin is deployed. It is not KEV-listed in the supplied data, but the potential site takeover impact justifies prompt inventory, update review, and account audit.
Technical view
CVE-2023-51398 is an improper privilege management issue, CWE-269, affecting Brainstorm Force Ultimate Addons for Beaver Builder through version 1.35.14. The CVSS 3.1 score is 8.8 with network access, low complexity, low privileges required, and no user interaction.
Likely exposure
Exposure is likely limited to WordPress sites running the premium Ultimate Addons for Beaver Builder plugin at version 1.35.14 or earlier. Risk is higher where untrusted or numerous low-privilege accounts can log in.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates exploitation requires an authenticated low-privilege account but no user interaction, which makes account-heavy WordPress environments more sensitive.
Researcher notes
The public bundle identifies the vulnerability class and affected range but does not include detailed root cause, exploit mechanics, or a named fixed version. Avoid assuming exploit availability or remediation specifics beyond vendor and Patchstack guidance.
Mitigation direction
- Identify all WordPress sites using Ultimate Addons for Beaver Builder Premium.
- Check installed plugin versions against the affected range through 1.35.14.
- Follow Brainstorm Force or Patchstack guidance for update or mitigation steps.
- Restrict creation and use of low-privilege WordPress accounts until remediated.
- Review administrator accounts and recent privilege changes.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record the exact installed plugin version and compare it with 1.35.14.
- Verify no unexpected administrator or elevated accounts exist.
- Review WordPress audit logs for suspicious role or capability changes.
- Document remediation status for each affected site.
