CVE-2026-48281

Think of ColdFusion like a program that accepts “instructions” from the internet. This flaw means it can be tricked into treating specially crafted input as real commands, which can let an attacker take over the server’s behavior. There’s no need for the attacker to log in or trick a user into clicking anything.

This matters if you use and expose Adobe ColdFusion to the network, especially if it’s reachable from the internet. The findings indicate the vulnerability can be exploited without authentication and without user interaction, so the main question is whether your ColdFusion is reachable by an attacker over the network. If your ColdFusion isn’t publicly reachable (or is tightly firewalled to trusted networks only), the practical risk is lower, but it can’t be ruled out until reachability is confirmed.

This is urgent because the flaw allows remote code execution without authentication or user interaction, meaning an attacker can potentially exploit it by sending crafted network requests. The issue is not listed as known exploited in the CISA KEV set, but it is still critical in nature for any internet-reachable ColdFusion system.
