The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-59558 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, described as PHP Remote File Inclusion but enabling PHP Local File Inclusion (CWE-98), in the ThemeMove Billey WordPress theme. This flaw affects Billey versions from n/a through those prior to 2.1.6.

Unauthenticated remote attackers can exploit the vulnerability over the network (AV:N) without user interaction (UI:N) and with no privileges required (PR:N), though it demands high attack complexity (AC:H). Exploitation within unchanged scope (S:U) can result in high confidentiality, integrity, and availability impacts (C:H/I:H/A:H), yielding a CVSS v3.1 base score of 8.1.

The Patchstack advisory details the Local File Inclusion vulnerability in the WordPress Billey theme and indicates it is addressed in version 2.1.6. Mitigation involves updating affected Billey installations to 2.1.6 or later.

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.

PR.PS-06 mostly match
blocks

Secure SDLC practices such as input validation and allow-listing of include paths directly prevent the weakness.

PR.PS-01 partial match
blocks

Hardened runtime configuration (e.g., allow_url_include=off) directly blocks RFI even if code is flawed.

PR.PS-05 partial match
blocks

Execution restrictions can prevent the remote payload from running, while eliminating the weakness reduces the need for such controls.

finds

Security testing can detect RFI but does not prevent the weakness by itself.

prevents

Secure coding standards directly require whitelisting and sanitization of filenames used in include/require statements.
