CVE-2026-57940
LOW
2.1
CVSS 4.0
Description
HTMLy 3.1.1 contains a Server-Side Request Forgery (SSRF) vulnerability in the RSS feed import functionality. The function get_feed() in system/admin/admin.php passes user-supplied $feed_url directly to file_get_contents() without any validation. An authenticated attacker with administrative privileges can exploit this by entering a crafted URL (e.g., http://dnslog.example.com, file:///etc/passwd, or http://169.254.169.254 in cloud contexts) via Tools -> Import RSS. The server will then make a request to the attacker-controlled target.
