Htmly

Server-Side Request Forgery in HTMLy 3.1.1 allows authenticated administrators to coerce the server into issuing arbitrary outbound HTTP or local filesystem requests via the RSS feed import feature. The vulnerable `get_feed()` function at `system/admin/admin.php` lines 1549-1551 passes the admin-supplied URL directly to PHP's `file_get_contents()` with no scheme filtering or allowlist validation, enabling access to cloud metadata endpoints (e.g., 169.254.169.254), internal network services, or local files via `file://` wrappers. No public exploit or CISA KEV listing exists at time of analysis; the CVSS 4.0 score of 2.1 reflects the high privilege prerequisite and limited confidentiality impact.

Arbitrary file relocation in HTMLy CMS through version 3.1.1 allows low-privileged authenticated users to move any web-server-writable file by injecting directory traversal sequences into the oldfile parameter of the admin autosave endpoint. Reported by VulnCheck with publicly available exploit code, the flaw stems from passing unsanitized input directly to file_exists() and rename() in admin.php. It is not listed in CISA KEV, so there is no public exploit identified as actively exploited at time of analysis despite the available POC.
