- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

- Published: 2026-02-14 · Updated: 2026-04-08

## Affected

- wpdecent Flexi Product Slider and Grid for WooCommerce: through 1.0.5

## Description

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.
