CVE-2026-54276

A flaw was found in aiohttp, an asynchronous HTTP client/server framework for asyncio and Python. The DigestAuthMiddleware component can send an authentication response after following a cross-origin redirect. This could allow a remote attacker, in conjunction with an open redirect vulnerability ...

CVE-2026-56234

Capgo before 12.128.2 contains a credential validation vulnerability in the POST /functions/v1/private/validatepasswordcompliance endpoint that is callable using only the public Supabase key without authentication. The endpoint is CORS-permissive with wildcard origin allowance and lacks rate...

JLSEC-2026-613 Redirect credential leakage across scheme/port in HTTP.jl

Description Redirect handling decided whether to retain credential-bearing headers Authorization, Cookie, Proxy-Authorization, etc. by comparing only the hostname, ignoring scheme and port. As a result an https→http downgrade or a same-host/different-port redirect was treated as same-origin and...

JLSEC-2026-615 Cookie jar accepts Secure/__Host-/__Secure- cookies from non-secure origins in HTTP.jl

Description setcookies! stored every parsed Set-Cookie after only checking that the response scheme was http or https, with no protection symmetric to the read path shouldsend, which already withholds Secure cookies from non-secure requests. A plaintext http origin could therefore plant a Secure...

JLSEC-2026-614 WebSocket default Origin check ignores scheme and port in HTTP.jl

Description The default WebSocket Origin validator originalloweddefault only enforced the host component of the same-origin tuple. It never checked the Origin's scheme, and when the request Host header carried no explicit port the norm for default-port 80/443 servers, where browsers omit the port...

CVE-2026-56234

Capgo prior to 12.128.2 exposes a credential validation endpoint (POST /functions/v1/private/validate_password_compliance) that is accessible with only the public Supabase key and lacks authentication. The endpoint uses permissive CORS with a wildcard origin and has no rate limiting, which enable...

CVE-2026-56234 Capgo - Password Spraying via Public-Key Accessible Credential Validation Endpoint

Capgo before 12.128.2 contains a credential validation vulnerability in the POST /functions/v1/private/validatepasswordcompliance endpoint that is callable using only the public Supabase key without authentication. The endpoint is CORS-permissive with wildcard origin allowance and lacks rate...

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...
