    CVE-2026-75899

    fast-uri vulnerable to server-side request forgery via repeated hostname percent-decoding

    fast-uri is a URI parser for Node.js. It decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authority recomposition, so a single call to normalize or resolve can turn nested percent-encoded input int…

    CVE-2026-75975

    fast-uri vulnerable to server-side request forgery via malformed IPv6 normalization

    fast-uri is a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not validate the complete IPv6 grammar, so invalid trailing text in an authority can be silently discarded and a malformed attacker-controlled host is turned into a diffe…

    CVE-2026-76172

    fast-uri vulnerable to host confusion via percent-encoded scheme normalization

    fast-uri is a URI parser for Node.js. During parsing it runs a legacy decoding pass over the scheme component and never re-escapes the result, and serialization writes the scheme back out verbatim, unlike the host component which is re-escaped. As a result an…

    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 de…
