Descripción técnica

Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.0.0 until 2.9.1, Addressable::IDNA.to_unicode can decode Punycode labels that contain bidirectional controls, zero-width characters, control characters, or other default-ignorable format characters. Addressable::URI#display_uri can consequently show a reordered or visually indistinguishable hostname even though host, normalized_host, and network connections use the original encoded hostname. The pure-Ruby backend accepts the full prohibited set, while the native libidn backend is affected from 2.5.2 for characters added after Unicode 3.2. This issue is fixed in version 2.9.1.

———Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.0.0 until 2.9.1, the pure-Ruby Addressable::IDNA.to_unicode implementation decodes invalid Punycode A-labels instead of returning them unchanged. Labels that decode to ASCII text or fail to convert back to the same A-label can therefore make Addressable::URI#display_uri show a trusted-looking host while host, normalized_host, and the connection target retain the attacker-controlled encoded host. A trusted-name comparison using Addressable::IDNA.to_unicode output can also treat two different hosts as the same without displaying the URI. The native libidn implementation, to_ascii, and normalized_host are unaffected. This issue is fixed in version 2.9.1.4h CVE-2026-1141718.8 ALT

——1Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an input validation vulnerability in the UPnP/DLNA AVTransport SOAP service that allows a LAN-adjacent attacker to inject arbitrary URIs via the CurrentURI field of SetAVTransportURI without validating the scheme, host, or media legitimacy. Attackers can supply schemes such as http://, file:///data/misc/wifi/, rtsp://, or smb:// to have the TV fetch and render attacker-controlled content after a one-time DLNA pairing, enabling phishing pages, fake firmware prompts, and fake emergency alerts to be displayed, with subsequent commands executing silently.5h CVE-2026-1212445.4 MED
