Summary

CVE-2026-28119 is a high-severity PHP Remote File Inclusion (CWE-98) vulnerability. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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.

CVE-2026-28119 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98 and commonly known as PHP Remote File Inclusion, though it enables PHP Local File Inclusion in the axiomthemes Nirvana (nir-vana) WordPress theme. This flaw affects all versions of the Nirvana theme up to and including 2.6. The vulnerability 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), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.

Attackers can exploit this vulnerability over the network without authentication or user interaction, though it requires high attack complexity. Successful exploitation allows remote unauthenticated attackers to perform local file inclusion, potentially leading to arbitrary code execution, data exposure, or system compromise depending on the included files and server configuration.

Patchstack has documented this vulnerability in their database for the WordPress Nirvana theme version 2.6, providing details at https://patchstack.com/database/Wordpress/Theme/nir-vana/vulnerability/wordpress-nirvana-theme-2-6-local-file-inclusion-vulnerability?_s_id=cve. Security practitioners should update to a patched version of the theme if available or remove it from production environments.

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
prevents

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

PR.PS-01 partial match
prevents

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

PR.PS-05 partial match
prevents

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 development lifecycle mandates input validation and safe include/require patterns that directly prevent remote file inclusion.

prevents

Application security requirements explicitly call for controls against injection and unsafe file operations.

prevents

Secure architecture principles reduce attack surface but do not specifically address dynamic file inclusion.

prevents

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

none

Information access restriction limits what files can be read but does not address dynamic inclusion logic.
