| CVE-2026-84394 | Hig | 0.42 | 7.5 | 0.00 | Sep 3, 2026 | 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()… | ||
| CVE-2026-84292 | Hig | 0.42 | 7.5 | 0.00 | Sep 2, 2026 | 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… | ||
| CVE-2026-76172 | Hig | 0.42 | 7.5 | 0.00 | Aug 24, 2026 | 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 input whose scheme… | ||
| CVE-2026-75975 | Hig | 0.42 | 7.5 | 0.00 | Aug 24, 2026 | 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 different valid IPv6… | ||
| CVE-2026-75931 | Hig | 0.42 | 7.5 | 0.00 | Aug 24, 2026 | fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is returned with its host verbatim and no error set. As a result fast-uri's own… | ||
| CVE-2026-75899 | Hig | 0.42 | 7.5 | 0.00 | Aug 24, 2026 | 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 into a different… | ||
| CVE-2026-16221 | Hig | 0.42 | 7.5 | 0.00 | Jul 19, 2026 | Impact: fast-uri versions from 2.3.1 through 4.1.0 (including the 3.x line up to 3.1.3 and the 2.x line up to 2.4.2) do not treat a literal backslash character (U+005C) as an authority delimiter. Node's native WHATWG URL parser, used by fetch, undici, and Node's http and https… | ||
| CVE-2026-13676 | Hig | 0.42 | 7.5 | 0.00 | Jun 29, 2026 | 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()… | ||
| CVE-2026-6322 | Hig | 0.42 | 7.5 | 0.01 | May 5, 2026 | fast-uri normalize() decoded percent-encoded authority delimiters inside the host component and then re-emitted them as raw delimiters during serialization. A host that combined an allowed domain, an encoded at-sign, and a different domain was re-emitted with the at-sign as a… | ||
| CVE-2026-6321 | Hig | 0.42 | 7.5 | 0.01 | May 4, 2026 | fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize() and equal() functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same… | ||
| CVE-2026-86472 | Med | 0.24 | 4.8 | 0.00 | Sep 15, 2026 | fast-uri is a dependency-free RFC 3986 URI parser for Node.js, used by Fastify and ajv. In versions before 2.4.7, from 3.0.0 through 3.1.7, and from 4.0.0 through 4.1.4, fast-uri folds the host to lowercase before it percent-decodes the host, so a percent-encoded uppercase octet… |
