Technical details
The plugin fails to properly validate or escape form shortcode attributes, allowing request parameters to be output without sanitization. This is a bypass of an incomplete fix for CVE-2023-5292; the previous patch covered only three HTML wrapper attributes, leaving other attributes vulnerable. A contributor-level user can craft a shortcode with unescaped attributes that reflect user input, leading to stored or reflected XSS when an administrator or any site user views the affected page.
Affected products

- Delicious Brains Advanced Custom Fields: Extended PRO 0.8.9.4 to 0.9.2.7
