## What is CVE-2026-1988?

CVE-2026-1988 is a high-severity path traversal vulnerability in wpdecent Flexi Product Slider and Grid for WooCommerce, published on 14 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program)
