Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2026-1988 is a high-severity PHP Remote File Inclusion (CWE-98) vulnerability in Mitre (inferred from references). Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 48% of CVEs by exploit likelihood; 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-1988 is a Local File Inclusion (LFI) vulnerability in the Flexi Product Slider and Grid for WooCommerce plugin for WordPress, affecting all versions up to and including 1.0.5. The issue arises in the `flexipsg_carousel` shortcode, where the `theme` parameter is directly concatenated into a file path without proper sanitization or validation, enabling directory traversal as described by CWE-98. Published on 2026-02-14, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).
Authenticated attackers with Contributor-level access or higher can exploit this vulnerability by creating posts that include the shortcode with a manipulated `theme` parameter. This allows them to include and execute arbitrary PHP files on the server, potentially leading to remote code execution.
References include the CWE definitions for PHP file inclusion (CWE-98) and path traversal (CWE-22), as well as source code locations in the plugin at line 82 of includes/class-flexipsg-shortcode.php in both the 1.0.5 tag and trunk versions on the WordPress plugin trac. Additional details are available in the Wordfence threat intelligence report.

Vulnerability Data
The Flexi Product Slider and Grid for WooCommerce plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.0.5 via the `flexipsg_carousel` shortcode. This is due to the `theme` parameter being directly concatenated into…

a file path without proper sanitization or validation, allowing directory traversal. This makes it possible for authenticated attackers, with Contributor-level access and above, to include and execute arbitrary PHP files on the server via the `theme` parameter granted they can create posts with shortcodes.

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.

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.
