Local File Inclusion in the ThemeMove 'Billey' premium WordPress theme (versions up to and including 2.1.8) lets an authenticated attacker with low privileges control a filename used in a PHP include/require statement, exposing sensitive server-side files such as wp-config.php. Classified by Patchstack under CWE-98 (PHP Remote File Inclusion) but resolving to Local File Inclusion in practice, the flaw carries a CVSS 7.5 rating and no public exploit identified at time of analysis. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Authenticate with low-privilege account
Delivery
Send crafted request with malicious filename parameter
Exploit
Bypass path validation in theme include
Execution
PHP include/require dereferences local file
Persist
Disclose sensitive files (wp-config.php)
Impact
Optionally chain to code execution

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with at least low-level privileges on the target WordPress site (CVSS PR:L), so anonymous/unauthenticated abuse is not indicated by the available data. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are mixed and warrant careful triage. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who holds or obtains a low-privilege authenticated WordPress account on a site running Billey <= 2.1.8 crafts a request to the vulnerable theme endpoint supplying a manipulated filename parameter that resolves to a sensitive local file (e.g., wp-config.php), causing the PHP include to disclose database credentials and secret keys. Given AC:H, the request likely requires specific parameter shaping or state to succeed, and under conditions permitting inclusion of attacker-controlled log or upload content it could be chained toward code execution. …
Remediation No vendor-released patch version is identified in the available data - the record states the issue affects Billey through <= 2.1.8 without naming a fixed release, so administrators should consult the Patchstack advisory (https://patchstack.com/database/Wordpress/Theme/billey/vulnerability/wordpress-billey-theme-2-1-8-local-file-inclusion-vulnerability?_s_id=cve) and the ThemeMove changelog for a version above 2.1.8 and upgrade to it as the primary fix once released. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all WordPress instances running Billey v2.1.8 or earlier and restrict new user provisioning on affected sites; increase monitoring for unusual file access patterns targeting configuration files. …
