DEBIAN-CVE-2026-13676

fast-uri versions 2.3.1 through 3.1.2 and 4.0.0 fail to canonicalize Unicode IDN hostnames for HTTP-family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize and equal still return...

BIT-NODE-2026-48930

A flaw in Node.js TLS hostname handling can cause Embedded-nul hostnames can lead to silent authority rebinding due to c-string truncation in resolver bindings. This vulnerability affects all supported release lines: Node.js 22, Node.js 24, and Node.js 26...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could create specific hostnames that, when processed by the matchpattern function, could lead to inefficient regular expression backtracking. This could cause timeouts and resource...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in the JDKFromStringDeserializer class, which constructs InetSocketAddress and resolves the hostname through DNS at deserialization time. An attacker can force the server to issue outbound DNS lookups fo...
