CVE-2026-14181 @fastify/middie standalone engine vulnerable to Denial of Service via malformed percent-encoded paths

@fastify/middie versions 9.1.0 through 9.3.2 fail to guard the URL normalization step used by the standalone engine when incoming request paths contain malformed percent-encoded sequences. Inputs such as an incomplete percent escape or a truncated multibyte sequence cause the underlying decoder t...

fast-uri: fast-uri: URI authority bypass due to improper delimiter handling

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier URI that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw...

CVE-2026-45822

A flaw was found in the decode-uri-component library. This vulnerability allows a remote attacker to trigger a Denial of Service DoS by submitting specially crafted input. The decode function, when processing a large number of encoded URI components, consumes excessive CPU resources, which can le...

CVE-2026-12243

A flaw was found in NLTK. An attacker can exploit a path traversal vulnerability by providing specially crafted input to nltk.data.load or nltk.data.find. This allows the attacker to read arbitrary files accessible to the Python process, leading to information disclosure. The vulnerability arises...
