CVE-2026-22416 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, referred to as PHP Remote File Inclusion, present in the AncoraThemes FixTeam WordPress theme. It enables PHP Local File Inclusion and affects versions from n/a through 1.5.0 inclusive. Published on 2026-03-05, the issue carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-98.
Remote attackers can exploit this vulnerability over the network without privileges or user interaction, though it requires high attack complexity. Successful exploitation grants high impacts on confidentiality, integrity, and availability, allowing attackers to perform local file inclusion, potentially leading to arbitrary code execution or data exposure on affected WordPress sites running the vulnerable theme.
The Patchstack advisory provides further details on the vulnerability in the WordPress FixTeam theme at https://patchstack.com/database/Wordpress/Theme/fixteam/vulnerability/wordpress-fixteam-theme-1-4-local-file-inclusion-vulnerability?_s_id=cve.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and static analysis can discover missing filename restrictions before deployment.
Validating all inputs before they reach include/require statements directly stops untrusted filenames from being used.
Enforcing access authorizations on resources limits what an included file can reach even if a bad name is supplied.
Information-flow rules can block the loading of external or unauthorized files into the PHP process.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure SDLC practices such as input validation and allow-listing of include paths directly prevent the weakness.
Hardened runtime configuration (e.g., allow_url_include=off) directly blocks RFI even if code is flawed.
Execution restrictions can prevent the remote payload from running, while eliminating the weakness reduces the need for such controls.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect RFI but does not prevent the weakness by itself.
Secure development lifecycle mandates input validation and safe include/require patterns that directly prevent remote file inclusion.
Application security requirements explicitly call for controls against injection and unsafe file operations.
Secure architecture principles reduce attack surface but do not specifically address dynamic file inclusion.
Secure coding standards directly require whitelisting and sanitization of filenames used in include/require statements.
Information access restriction limits what files can be read but does not address dynamic inclusion logic.
