Mercusys AC12G EU V1 router with firmware AC12GEUV1200909 does not validate the HTTP Host header, enabling DNS rebinding attacks. An external attacker can rebind a domain to the router's internal IP address, extending the CORS wildcard vulnerability Access-Control-Allow-Origin: to...

CVE-2026-6657 CORS Origin Validation Bypass in jupyter-server

A vulnerability in jupyter-server versions 1.12.0 through 2.17.0 allows an attacker to bypass CORS origin validation when the alloworiginpat configuration is used. The issue arises from the use of re.match for validating the Origin header, which only anchors at the start of the string. This allow...

Langflow AI <= 1.6.9 - CORS Misconfiguration

Langflow AI versions 1.6.9 and earlier are vulnerable to a CORS misconfiguration that allows any origin to make credentialed requests. Combined with SameSite=None cookies, this enables cross-origin token theft and subsequent remote code execution via the /api/v1/validate/code endpoint. id:...
