EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 67% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
