Comment2Shell: Zero-Click Pre-Auth XSS to RCE in WordPress Core
A comment from an anonymous visitor could turn into stored XSS, and eventually RCE, on a WordPress site running a block theme, because wpautop() swaps a newline inside an HTML attribute value for an HTML comment, and its blockquote rewrite then mistakes that comment's closing bracket for the end of the tag. Fixed in WordPress 7.1.1 as CVE-2026-93485.
