CVE-2026-55501 9router: Login brute-force protection bypass via spoofed X-Forwarded-For header

9Router is an AI router & token saver. Prior to 0.4.80, the dashboard login rate limiter in src/lib/auth/loginLimiter.js derives the client identity from the attacker-controlled X-Forwarded-For HTTP header, and src/app/api/auth/login/route.js uses that spoofable value for checkLock and recordFail...

urllib3: urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers

A flaw was found in urllib3, an HTTP client library for Python. When using the low-level API via ProxyManager.connectionfromurl.urlopen with assertsamehost=False, cross-origin redirects can still forward sensitive headers. This could allow a remote attacker to gain unauthorized access to sensitiv...
