CVE-2026-109973

The Image Hover Effects Ultimate Visual Composer (Flipbox - Awesomes Flip Boxes Image Overlay) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'flip-box-image-upload-url-01-alt' parameter in versions up to, and including, 3.1.1. This is due to the plugin saving the image-alt field through sanitize_text_field() in Inc/Style22::register_child() (and Inc/Style18, 19, 20, 25, 29) — which preserves the double-quote character — and then concatenating the stored value into a double-quoted HTML attribute in Public_Render/Style22::default_render() (and the corresponding Style18/19/20/25/29 renderers) with no esc_attr() escaping. This makes it possible for authenticated attackers, with contributor-level access and above (when an administrator has delegated the plugin's 'Who can edit' capability via the plugin Settings page, or on multisite installations where even administrators lack unfiltered_html), to inject arbitrary web scripts in pages that will execute whenever a user accesses any page containing an affected [oxilab_flip_box] shortcode or block.

Affected products and versions

NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.

Remediation & validation

  1. Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
  2. Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
  3. Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
  4. Validate the remediation with a version check and vulnerability rescan, then retain change evidence.

No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
