## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the Snippets Free and Pro extensions. Snippets substitutes article author-supplied variable values (via url option) into pre-defined snippet content without validating the author's privilege level. A lower-privileged author can inject malicious JavaScript into a security-sensitive position within a snippet authored by a trusted administrator. The injected payload persists in the database and executes whenever the snippet is rendered, affecting all website visitors. Patches are available in Snippets Free 7.0.0+ and Snippets Pro 11.0.0+.
