CLSA-2026-1788432470 TuxCare security update for fast-uri (5 CVEs)
TuxCare rebuilt fast-uri to address 5 CVEs. Fixed in 2.4.3-tuxcare.2...
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-2026-84394
A flaw was found in fast-uri. The library incorrectly processes Uniform Resource Identifier URI hosts containing unbalanced brackets, leading to a discrepancy in how the host is parsed by fast-uri compared to other HTTP clients. This host confusion can allow an attacker to bypass security policie...
CVE-2026-84292
A flaw was found in fast-uri. This component improperly serializes the port component of a Uniform Resource Identifier URI without validating its content. A remote attacker can exploit this by crafting a malicious port value that injects authority delimiters. This manipulation can demote the...
CVE-2026-84394 fast-uri vulnerable to host confusion via an unclosed bracket in the URI authority
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-2026-84394
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-2026-84292
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 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-2026-84292
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...

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...

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-FPH4-WMHF-6FWF fast-uri vulnerable to server-side request forgery via repeated hostname percent-decoding
Impact fast-uri decodes a hostname's percent escapes twice in a single normalize or resolve call: once during parsing and again during authority recomposition. A nested percent-encoded host therefore survives the first decode and is turned into a live destination by the second, so...
