Security readout for executives and security teams
Plain-English summary
This is a high-severity WordPress plugin issue in Page Builder: Live Composer through version 1.5.25. A highly privileged user could trigger unsafe PHP object deserialization, potentially affecting confidentiality and integrity. The sources do not show active exploitation or a confirmed fixed version.
Executive priority
Treat this as a priority for WordPress estates using the plugin, especially public business sites. The issue requires high privileges, but successful abuse could affect sensitive content and site integrity. Confirm exposure first, then remediate or remove the plugin according to vendor guidance.
Technical view
CVE-2023-52206 is CWE-502 deserialization of untrusted data in live-composer-page-builder. CVSS 3.1 is 7.7: network reachable, high attack complexity, high privileges required, no user interaction, changed scope, high confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is limited to WordPress installations running Page Builder: Live Composer through 1.5.25. The CVSS vector indicates exploitation requires high privileges, so compromised or malicious privileged WordPress accounts are the key exposure path.
Exploitation context
The provided bundle lists KEV as false and gives no cited evidence of active exploitation. Because privileges and attack complexity are high, this is less likely to be broad unauthenticated scanning, but it remains serious on sites with weak admin controls.
Researcher notes
Evidence is sparse in the provided sources. The affected range is described as through 1.5.25, with no CPEs and no explicit fixed version in the bundle. CVSS privileges-required high should guide validation and risk ranking.
Mitigation direction
- Inventory WordPress sites for live-composer-page-builder through version 1.5.25.
- Check vendor and Patchstack guidance for a patched release or supported mitigation.
- Remove or disable the plugin where it is not business-critical.
- Restrict and review privileged WordPress accounts on affected sites.
- Prioritize MFA and least privilege for WordPress administrators.
Validation and detection
- Confirm installed plugin name, slug, and version on each WordPress site.
- Identify sites running Page Builder: Live Composer version 1.5.25 or earlier.
- Review privileged account activity for unexpected plugin or content changes.
- Verify whether vendor guidance names a safe upgraded version.
- Document exceptions where the plugin cannot be removed or upgraded.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
