Unauthenticated PHP execution via cached comment tags

Published Feb 7, 2020 · Updated Aug 6, 2024

Remote code execution in Automattic WP Super Cache 1.2 allows remote attackers to execute arbitrary PHP through a crafted WordPress comment. The dynamic-cache parser interprets unfiltered mfunc, mclude, and dynamic-cached-content HTML comment tags as executable PHP directives. The site must accept the crafted comment and cache the affected page, after which the code runs in the web server's PHP context.
