CVE-2026-88852 – Joomla Extension – regularlabs.com – Privileged stored XSS via url option in Snippets Free

Joomla Extension – regularlabs.com – Privileged stored XSS via url option in Snippets Free extension for Joomla < 7.0.0, Snippets Pro extension for Joomla < 11.0.0 – Snippets substitutes variable values supplied by an article tag into saved Snippet content. The affected versions do not consider the article author's trust level. A lower-privileged author can therefore place an unsafe value into a security-sensitive position chosen by the trusted Snippet author.
