CVE-2026-60105 is an unauthenticated server-side request forgery vulnerability in Monsta FTP versions before 2.14.5. The fetchRemoteFile action retrieves an attacker-supplied HTTP or HTTPS resource from the Monsta FTP host and transfers the resulting response to an FTP destination supplied by the requester. Its IP-validation routine incompletely applies IPv4 denylist checks to IPv4-mapped IPv6 addresses, allowing representations of otherwise restricted loopback, private, link-local, and cloud-metadata destinations to bypass validation. The post-connection destination-IP check intended to mitigate DNS rebinding invokes the same flawed routine and is likewise bypassable.

An unauthenticated server-side request forgery (SSRF) vulnerability in Monsta FTP versions 2.14.4 and earlier, reportedly enabling an IPv6 blocklist-bypass technique.
An unauthenticated SSRF vulnerability in Monsta FTP caused by incomplete IP blocklist validation that fails to properly normalize IPv4-mapped IPv6 addresses, allowing access to cloud metadata and internal network resources.
A server-side request forgery vulnerability in Monsta FTP before 2.14.5 caused by an incomplete IP blocklist check that can be bypassed using IPv4-mapped IPv6 addresses, allowing unauthenticated access to internal services and potential retrieval of cloud metadata credentials.
