CVE-2026-84394

fast-uri (a URI parsing library used by the Fastify ecosystem) contains a host confusion vulnerability: when a URI's authority contains an opening bracket [ without a matching closing bracket ], parse() returns the string as the host without error. Neither an IP literal nor a valid domain name is...

CVE-2026-84394

fast-uri accepts a host that contains an unbalanced or misplaced authority bracket without reporting an error. A host that starts with an opening bracket but does not end with a closing bracket is neither validated as an IP literal nor canonicalized as a domain name, so parse returns it as the ho...

CVE-2026-84292

fast-uri serializes the port component of a URI without validating it. When recomposing the authority, the userinfo and host components are escaped but the port is concatenated verbatim, so a port value that is not a sequence of digits can inject authority delimiters, demoting the intended host t...

CVE-2026-84292

fast-uri , a URI library in the Fastify ecosystem, fails to validate the port component when serializing an authority. The recomposeAuthority function concatenates the port verbatim without escaping, so a crafted non-digit value (e.g., containing @) can inject authority delimiters, demoting the i...

CVE-2026-84292 fast-uri vulnerable to authority injection via an unvalidated port in serialize

fast-uri serializes the port component of a URI without validating it. When recomposing the authority, the userinfo and host components are escaped but the port is concatenated verbatim, so a port value that is not a sequence of digits can inject authority delimiters, demoting the intended host t...

CVE-2026-79755

Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.17.4, on the Nuclio local Docker platform, the function namespace is interpolated—unvalidated—into a double-quoted docker ps --filter "label=nuclio.io/namespace=" command that is executed via the host...

GHSA-5JGF-P345-68V8 fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

Impact fast-uri canonicalizes a host to its ASCII form only when the input carries an explicit scheme. When resolve resolves a scheme-relative reference //host/ against a scheme-bearing base, it still emits the host verbatim even though the effective scheme is known, so re-parsing the resolved UR...

GHSA-F65P-4M7J-42XC fast-uri vulnerable to server-side request forgery via malformed IPv6 normalization

Impact fast-uri does not validate the complete RFC 3986 grammar for bracketed IPv6 literals, so a malformed literal with invalid trailing text is silently truncated to a different valid IPv6 address with no error reported. For example, normalize'http://::not-valid/private' returns...

GHSA-JQFF-G426-HQXP fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Impact fast-uri decodes percent-encoded characters in the scheme component with the legacy global unescape and serializes the result back as raw characters, without re-escaping it or validating it as a scheme. A scheme that decodes to characters outside the RFC 3986 scheme grammar can therefore...

SUSE CVE-2026-19953

URI versions before 5.36 for Perl encode non-NFC host names to non-standard punycode labels via missing normalization in nameprep. nameprep lowercases each host label but performs no Unicode normalization. IDNA requires a label to be normalized to Form C before it is encoded RFC 5891, so a label...
