CVE-2026-75931 fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

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 entry points disagr...

Name of the Vulnerable Software and Affected Versions fast-uri versions 2.4.2 through 2.4.4 fast-uri versions 3.1.3 through 3.1.5 fast-uri versions 4.0.1 through 4.1.2 Description fast-uri, a URI parser for Node.js, fails to consistently canonicalize hosts to ASCII form when processing...

CVE-2026-75931: Interpretation Conflict

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 entry points disagr...

Name of the Vulnerable Software and Affected Versions fast-uri versions 2.3.1 through 2.4.4 fast-uri versions 3.0.0 through 3.1.5 fast-uri versions 4.0.0 through 4.1.2 Description The custom parser for bracketed IPv6 literals fails to validate the complete IPv6 grammar. This allows invalid traili...

Name of the Vulnerable Software and Affected Versions fast-uri versions 2.4.1 through 2.4.4 fast-uri versions 3.1.2 through 3.1.5 fast-uri versions 4.0.0 through 4.1.2 Description This URI parser for Node.js decodes percent escapes in a hostname during parsing and subsequently decodes the parsed...

CVE-2026-75899: Double Decoding of the Same Data

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 network destination such...

CVE-2026-76172: Improper Handling of URL Encoding (Hex Encoding)

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 carries...

CVE-2026-76835: Authentication Bypass by Spoofing

OAuth2 Proxy honours a client-supplied X-Forwarded-Uri header when deciding whether a request may skip authentication, because the guard added for CVE-2026-40575 is inert in the default reverse-proxy configuration. GetRequestURI in pkg/requests/util/util.go prefers that header over the real reque...

Fabric.js loadFromJSON Server-Side Request Forgery Vulnerability

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Fabric.js. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the...

CVE-2026-75975: Improper Input Validation

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 destination. For...

dompurify: DOMPurify: URI validation bypass leads to cross-site scripting

A flaw was found in DOMPurify. An attacker can bypass URI validation by providing a specially crafted predicate function via EXTRAELEMENTHANDLING.attributeCheck. This allows unsafe protocols, such as javascript:, to persist after sanitization, potentially leading to DOM-based cross-site scripting...

SUSE CVE-2026-63385

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has two HTTP parsing weaknesses in http.c. evhttpdecodeuriinternal decodes percent-encoded %00 bytes into literal NUL characters, which can cause downstream C string operations to truncate a path and bypass...

oauth2-proxy: github.com/oauth2-proxy/oauth2-proxy: OAuth2 Proxy: Authentication bypass due to spoofed X-Forwarded-Uri header

A flaw was found in OAuth2 Proxy. When configured with --reverse-proxy and either --skip-auth-regex or --skip-auth-route, the proxy may trust a client-supplied X-Forwarded-Uri header. An unauthenticated remote attacker can exploit this by spoofing the header, leading to an authentication bypass...

Fedora 44 : perl-URI (2026-32b0d26c4c)

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-32b0d26c4c advisory. 5.36 - Apply Unicode NFC normalization in URI::idna nameprep so IDNA host encoding matches other clients instead of emitting a non-standard, non-round-trippi...
