Adobe ColdFusion EUVD-2026-56539

No special conditions - remote unauthenticated exploitation against network-reachable Adobe ColdFusion 2023 and 2025 instances, per the CVSS vector AV:N/AC:L/PR:N/UI:N and the description's statement that exploitation does not require user interaction. The practical limiting factor is network reachability: the ColdFusion service (or the specific vulnerable endpoint) must be accessible to the attacker, so instances confined to trusted internal networks or behind strict access controls face materially lower risk than internet-exposed deployments. No non-default feature toggle or configuration setting is named in the available data as a prerequisite.

This is a top-priority vulnerability with essentially every risk signal maximized: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H yields a perfect 10.0, indicating network-reachable, low-complexity, unauthenticated exploitation with full confidentiality, integrity, and availability impact and a scope change onto the host. No EPSS score, KEV listing, or SSVC decision data was supplied, so probabilistic and active-exploitation signals cannot be independently corroborated here - the urgency rests on the vector and product history rather than confirmed in-the-wild activity. Given ColdFusion's long track record of being rapidly weaponized after disclosure, even a mid-sized municipal IT team in bytom should treat this as urgent and patch before exploit code circulates. In short, this is a genuine emergency-patch item, not a high-CVSS-but-low-real-risk case, though defenders should verify EPSS and KEV status directly as those inputs were absent.

An attacker locates an internet-exposed ColdFusion 2023 or 2025 instance and sends a crafted HTTP request containing shell metacharacters to the vulnerable endpoint, breaking out into an OS command that runs with the privileges of the ColdFusion service. Because no authentication or user interaction is required and complexity is low, the attacker can immediately execute commands to drop a web shell, harvest credentials, or pivot into the host. No public exploit identified at time of analysis, but the low-complexity, unauthenticated nature makes reliable exploitation straightforward once a payload is developed.
