Title
LiteSpeed Cache <= 7.9.1 - Unauthenticated Stored Cross-Site Scripting via HTML Minifier Predictable Placeholder (md5(REQUEST_TIME) + two-pass str_replace)
Summary
The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 7.9.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when the HTML Minify option (O_OPTM_HTML_MIN) is enabled and a companion plugin renders stored comment content into a raw-text context such as a JSON-LD script block on the same page.
