Snipe-IT: Multiple Vulnerabilities allow Umgehen from Sicherheitsvorkehrungen and potenziell Cross-Site Scripting

CVSS N/A NONE

Risk Summary

league/commonmark is a PHP Markdown parser. From version 2.3.0 to before version 2.8.2, the DomainFilteringAdapter in the Embed extension is vulnerable to an allowlist bypass due to a missing hostname boundary assertion in the domain-matching regex. An attacker-controlled domain like youtube.com.evil passes the allowlist check when youtube.com is an allowed domain. This issue has been patched in version 2.8.2.
