CVE-2026-37107 Details
Description
An issue in HTMLy v.3.1.1 allows a remote attacker to escalate privileges via the get_feed function in the admin.php component
A privilege escalation vulnerability has been identified in HTMLy version 3.1.1. This issue arises from the feed import functionality in the admin.php component, where the get_feed function fails to validate URL schemes before fetching content. As a result, an authenticated remote attacker can exploit this flaw to read arbitrary local files or probe internal network services.
Users are advised to validate URL schemes before fetching content in the feed import functionality. Additionally, keep the display_errors configuration off in production environments and upgrade HTMLy once a patched version is available.
