CVE-2026-88852 — 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.
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.
