Editor PHP Object Injection in OptionTree <= 2.7.3 versions.
AnalysisAI
PHP Object Injection in the OptionTree WordPress plugin (versions <= 2.7.3) enables authenticated administrators to submit crafted serialized PHP data through the plugin's Editor interface, triggering dangerous deserialization that can culminate in arbitrary code execution on the host server. The CVSS vector (PR:H) confirms that exploitation is gated behind WordPress administrator credentials, constraining the immediate threat surface. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress administrator account (confirmed by CVSS PR:H). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.2 score with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H signals high impact across all three pillars but with the important mitigating factor of high-privilege prerequisite. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained WordPress administrator credentials - whether through phishing, credential stuffing, or a separate compromise - logs into the site's admin panel and navigates to the OptionTree Editor interface. The attacker submits a POST request containing a crafted serialized PHP object that encodes a POP chain leveraging classes present in the WordPress or plugin codebase, causing the server to execute arbitrary PHP code in the web server process context. … |
| Remediation | No vendor-released patched version has been independently confirmed from the available intelligence data - the affected range is listed only as <= 2.7.3 with no stated fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit all WordPress installations to identify OptionTree plugin deployments (version 2.7.3 and earlier) and restrict editor access to only essential administrator accounts; document all active administrators with plugin Editor interface permissions. …
