Security readout for executives and security teams
Plain-English summary
This is a high-severity cross-site scripting issue in the YITH WooCommerce Product Add-Ons WordPress plugin through version 4.5.0. Affected storefronts could expose shoppers, admins, or staff to browser-side script execution after user interaction, potentially affecting confidentiality, integrity, and availability at a limited level.
Executive priority
Treat this as a near-term e-commerce platform risk, especially for public storefronts using the affected plugin. Prioritize inventory and vendor-guided remediation, but do not treat it as confirmed actively exploited based on the supplied evidence.
Technical view
CVE-2024-27994 is CWE-79 improper input neutralization during web page generation in yith-woocommerce-product-add-ons. The CVSS 3.1 score is 7.1, with network attack vector, low complexity, no privileges required, required user interaction, changed scope, and low C/I/A impact.
Likely exposure
Exposure is likely limited to WordPress and WooCommerce sites running YITH WooCommerce Product Add-Ons version 4.5.0 or earlier. The bundle does not identify affected configurations beyond the plugin and version range.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not listed as KEV. The CVSS vector indicates exploitation is network-reachable, low complexity, unauthenticated, and requires user interaction.
Researcher notes
The evidence is strong for affected product, version range, CWE, and CVSS characteristics. It is incomplete on fixed version, proof details, affected parameters, and exploitation in the wild, so validation should avoid assumptions beyond the advisory data.
Mitigation direction
- Inventory WordPress/WooCommerce sites for yith-woocommerce-product-add-ons version 4.5.0 or earlier.
- Check YITHEMES and Patchstack guidance for the corrected version or vendor-recommended workaround.
- Update the plugin through standard WordPress maintenance once a trusted fixed release is confirmed.
- Temporarily disable the plugin where business risk outweighs add-on functionality.
- Prioritize admin and checkout-facing pages for review after remediation.
Validation and detection
- Confirm installed plugin name and version on every WooCommerce site.
- Verify whether any instance runs version 4.5.0 or earlier.
- Review vendor or Patchstack advisory details before declaring remediation complete.
- Run normal regression checks for product add-on and checkout workflows after updating.
- Check security monitoring for suspicious script injection or unusual WordPress activity.
