EPSS Score95.8%

EPSS (Exploit Prediction Scoring System) estimates a 95.8% chance this CVE is exploited in the wild within the next 30 days — higher than 100% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

WordPress Core contains a remote file inclusion vulnerability which could allow an unauthenticated attacker to make page-template resolution include a chosen readable local `.php` file outside the active theme directories, leading to remote code execution.

Required Action

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Description

An unauthenticated attacker can make `get_page_template()` page-template resolution include a chosen readable local `.php` file outside the active theme directories. If relevant pre-conditions for both the server and the active theme are met, this can lead to RCE.
