Adobe ColdFusion Path Traversal Vulnerability
Adobe · ColdFusion
Adobe ColdFusion contains a path traversal flaw (improper limitation of a pathname to a restricted directory) that affects ColdFusion versions 2025.9, 2023.20 and earlier. An unauthenticated remote attacker with network access can exploit it without user interaction, and it can lead to arbitrary code execution in the context of the current user.
ColdFusion versions 2025.9, 2023.20 and earlier are affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction. Scope is changed.
