Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
AC:H because real impact requires a POP chain in a separately-installed component, a condition entirely outside the attacker's control.

3DescriptionCVE.org
The Live Composer - Free WordPress Website Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.1.18 via deserialization of untrusted input . This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

AnalysisAI
PHP Object Injection in the Live Composer - Free WordPress Website Builder plugin (all versions ≤ 2.1.18) enables authenticated attackers with contributor-level access to inject arbitrary PHP objects via deserialization in the plugin's downloads module. Real-world impact is entirely conditional on whether a Property-Oriented Programming (POP) chain is present in a co-installed plugin or theme; without one, exploitation produces no tangible effect. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) contributor-level WordPress authentication or higher - anonymous or subscriber-level access is insufficient per the CVSS PR:L vector; (2) a Property-Oriented Programming (POP) chain must be present via a separately-installed plugin or theme on the same WordPress instance, as the vulnerable plugin itself contains no known gadget chain; and (3) Live Composer - Free WordPress Website Builder version 2.1.18 or earlier must be installed and active. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a worst-case scenario that assumes a POP chain is already available on the target site, but the Wordfence advisory explicitly states no POP chain exists within the vulnerable plugin itself - meaning impact is zero on WordPress instances where no co-installed component supplies gadget classes. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update the Live Composer - Free WordPress Website Builder plugin via the WordPress admin dashboard or WP-CLI to the version released in SVN changeset 3628023 (https://plugins.trac.wordpress.org/changeset/3628023/), which represents the upstream fix; a specific patched release version number is not independently confirmed in the available data, so administrators should install the latest available version above 2.1.18 and verify it post-dates this changeset. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all WordPress instances running Live Composer to identify current version and inventory co-installed plugins and themes; cross-reference against known PHP object injection gadget chain sources (WPScan, security databases); restrict the creation of new contributor-level accounts and review existing ones. …
