SUSE CVE-2026-86472

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 such as %41 decod...

CVE-2026-77405 RabbitMQ amqp091-go: Missing Explicit TLS Minimum Version Configuration In URI Parser

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, tlsConfigFromURI in uri.go creates tls.Config values without setting MinVersion to tls.VersionTLS12. Builds using a Go runtime whose default permits TLS 1.0 or TLS 1.1 can therefore negotiate an obsolete protocol version when...

CVE-2026-86472

A flaw was found in fast-uri, a dependency-free URI parser. This vulnerability occurs because the software folds the host to lowercase before percent-decoding it, allowing percent-encoded uppercase characters to bypass this normalization. A remote attacker could exploit this by crafting a malicio...

CVE-2026-86818 fast-uri vulnerable to mailto header injection via percent-encoded field-name desynchronization

fast-uri is a dependency-free RFC 3986 URI parser for Node.js, used by Fastify and ajv, that added a mailto scheme parser in version 4.1.3. In versions 4.1.3 and 4.1.4, the mailto parser compares each query field name to the reserved names to, subject, and body while the name is still...

CVE-2026-86472 fast-uri vulnerable to inconsistent host case normalization via percent-encoded octets

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 such as %41 decod...

Astra Linux – Vulnerability in JRuby

A ReDoS issue was discovered in the URI component through 0.12.0 in Ruby, up to 3.2.1. The URI parser improperly handles invalid URLs that contain specific characters. This leads to an increase in the execution time required to parse strings into URI objects. The fixed versions are 0.12.1, 0.11.1...

fast-uri: fast-uri: Host confusion via skipped IDN canonicalization

A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names IDN to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an...

fast-uri: fast-uri: Server-Side Request Forgery via repeated hostname percent-decoding

A flaw was found in fast-uri, a URI parser for Node.js. The component incorrectly decodes percent escapes in a hostname twice during URI parsing and authority recomposition. This double decoding can allow a remote attacker to manipulate a URI to point to a different network destination, such as a...

fast-uri: fast-uri: Server-side request forgery via malformed IPv6 normalization

A flaw was found in fast-uri, a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not fully validate the IPv6 grammar, allowing invalid trailing text in an authority to be silently discarded. This can lead to a malformed, attacker-controlled host being normalized into a...
