fast-uri vulnerable to host confusion via literal backslash authority delimiter

Impact fast-uri v4.1.0 and earlier do not treat a literal backslash U+005C as an authority delimiter. Node's native WHATWG URL used by fetch, undici, and Node's http/https clients normalizes \ to / for special schemes http, https, ws, wss, ftp, file, so the two parsers extract different hosts fro...

GHSA-5QHF-9PHG-95M2 Loofah `allowed_uri?` does not detect `javascript:` URIs split by numeric character references without semicolons

Summary Loofah::HTML5::Scrub.alloweduri? does not correctly reject javascript: or vbscript: URIs when the scheme is split by a numeric character reference that has no trailing semicolon. A browser decodes such references and resolves the URL to an executable javascript: scheme, while alloweduri?...

Server-side Request Forgery (SSRF)

OpenTelemetry JavaScript: Denial of service in `JaegerPropagator` via unhandled exception on a malformed header

Summary @opentelemetry/propagator-jaeger decodes incoming HTTP header values with decodeURIComponent without handling decode errors. A single request carrying a malformed percent-encoded value for example a bare % in an uber-trace-id or uberctx- header throws an uncaught URIError, terminating any...
