Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates CVE-2026-22478 by requiring timely remediation of the known PHP Local File Inclusion flaw in vulnerable FindAll WordPress theme versions through patching or upgrades.

SI-10 Information Input Validation good match
prevent

Enforces validation and sanitization of user-supplied filenames in PHP include/require statements to block malicious local file inclusion paths exploited in this vulnerability.

CM-6 Configuration Settings partial match
prevent

Establishes secure baseline PHP and web server configuration settings, such as open_basedir restrictions, to limit file system access and mitigate LFI exploitation attempts.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
attack.mitre.org →
T1083 File and Directory Discovery Discovery
Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.
attack.mitre.org →
T1552.001 Credentials In Files Credential Access
Adversaries may search local file systems and remote file shares for files containing insecurely stored credentials.
attack.mitre.org →
Why these techniques?

LFI in public-facing WordPress theme enables exploitation of public app (T1190), local file reads for data (T1005), discovery (T1083), and credentials (T1552.001).
