SmartScreen is a built‑in Windows feature that helps protect users from malicious websites and downloaded files. This bypass vulnerability allows an attacker to inject code into SmartScreen, potentially gaining code execution and compromising data confidentiality and system availability.

This server‑side request forgery (SSRF) vulnerability resides in the SAML component of Ivanti Connect Secure VPN. When chained with CVE‑2024‑21887 (an authenticated command injection vulnerability), an attacker can achieve unauthenticated remote code execution (RCE) against vulnerable Ivanti VPN appliances. China‑linked APT group UNC5221 has been observed exploiting both vulnerabilities in a coordinated espionage campaign affecting a wide range of global sectors.
