CVE-2026-95811

Lemonldap::NG::Handler versions from 2.0.0 before 2.16.10, from 2.17.0 before 2.21.6, from 2.22.0 before 2.23.4 for Perl allow an equivalent spelling of a path to bypass the locationRules that restrict it. The handler matches each vhost's locationRules regular expressions against REQUESTURI, the...

CVE-2026-69201

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, ResourceService and WebjarService decode each URL path segment but reject only segments exactly equal to an empty string, a dot, or two dots. A request containing percent-encoded slash or backslash separators can turn ...

CVE-2026-69201 Http4s: ResourceService and Webjar Service path escape via percent-encoded separators

Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, ResourceService and WebjarService decode each URL path segment but reject only segments exactly equal to an empty string, a dot, or two dots.

CVE-2026-86818

A flaw was found in fast-uri, a Node.js URI parser. In versions 4.1.3 and 4.1.4, the mailto parser incorrectly handles percent-encoded query field names. This desynchronization between parsing and serialization allows an attacker to inject arbitrary recipients, subjects, or body content into mail...

DEBIAN-CVE-2026-86818

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 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-2026-86472

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...

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-2026-86818

fast-uri v4.1.3–4.1.4, a dependency-free RFC 3986 URI parser for Node.js used by Fastify and ajv , suffers from a percent-encoded field-name desynchronization in its mailto parser. At parse time, reserved field names (to, subject, body) are compared in their still-percent-encoded form and thus no...

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 is a dependency-free RFC 3986 URI parser for Node.js used by Fastify and ajv . In versions before 2.4.7, 3.0.0–3.1.7, and 4.0.0–4.1.4, the library folds the host to lowercase before percent-decoding, so a percent-encoded uppercase octet (e.g. %41 → A) is never folded. For scheme-relative...

CVE-2026-86818: Encoding Error
