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...
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...
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-2026-75899 fast-uri vulnerable to server-side request forgery via repeated hostname percent-decoding
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...

OSEC-2026-16 Path traversal in Cohttp.Path.resolve_local_file
The issue is that the function normalizes the URI path before percent decoding it: OCaml let resolvelocalfile docroot uri = let path = Uri.pctdecode path resolve "http" ofstring "/" uri in ... Because %2f is decoded after Uri.resolve, encoded separators survive dot-segment normalization. For...
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...
USN-8470-1: cpp-httplib vulnerability
It was discovered that cpp-httplib incorrectly percent-decoded HTTP request header values. A remote attacker could use this to inject crafted header content possibly leading to response splitting, log injection or proxy smuggling...
GHSA-P88M-4JFJ-68FV undici vulnerable to HTTP header injection via Set-Cookie percent-decoding
Impact undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded sequences like %0D%0A, %00, %3B, and %3D into their literal byte equivalents. RFC 6265 §5.4 does not specify any decoding and browsers do not decode either. Applications that parse a...
AZL-91188 CVE-2026-9679 affecting package nodejs for versions less than 24.18.1-1
Impact: undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded sequences like %0D%0A, %00, %3B, and %3D into their literal byte equivalents. RFC 6265 §5.4 does not specify any decoding and browsers do not decode either. Applications that parse a...

python-multipart: Content-Disposition parameter smuggling via RFC 2231/5987 extended parameters
Summary parseoptionsheader parsed Content-Disposition and Content-Type headers with email.message.Message, which transparently applies RFC 2231/5987 decoding.

SUSE CVE-2026-45372
cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.44.0, when cpp-httplib's server parses an incoming request, it applies percent-decoding to every header value except Location and Referer. The validity check isfieldvalue is run before decoding, so encode...

CVE-2026-45372
In cpp-httplib, prior to version 0.44.0, the server-side header parsing in parse_header applies percent-decoding to header values (except Location and Referer) after validating the pre-decoded string. The validity check (is_field_value) runs before decoding, allowing an encoded %0D%0A to bypass c...
