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...

CVE-2026-66746-HTTP-Response-Splitting-via-Unvalidated-Response-Header-Values-rouille-

Security Advisory: HTTP Response Splitting via Unvalidated Response Header Values rouille Assigned CVE ID: CVE-2026-66746 Summary rouille writes response header values to the client without checking them for carriage return or line feed. An application that places attacker-influenced text into a...

fast-uri: fast-uri: Security bypass due to inconsistent host case normalization

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...

Path Traversal

Http4s is vulnerable to a Path Traversal.The vulnerability is due to improper validation of URL path segments after percent-decoding, which allows an attacker to use encoded slash or backslash separators to traverse parent directories and access classpath or WebJar resources outside the configure...

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...

CVE-2026-63385

Libevent versions before 2.1.13 and 2.2.2-alpha contain two HTTP parsing flaws in http.c: evhttp_decode_uri_internal decodes %00 into literal NUL bytes, truncating paths to bypass validation; evhttp_header_is_valid_value accepts obsolete line folding with CRLF, enabling header injection and acces...

CVE-2026-19670 Incorrect Authorization in CISA Malcolm

Malcolm's nginx Lua role-based access control RBAC layer decides whether an authenticated user may reach a role-restricted path e.g. /htadmin, /auth, /adminlogin, /arkime/api/esadmin, NetBox, upload endpoints by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects...
