Detailsinfo

A vulnerability, which was classified as problematic, has been found in Adobe ColdFusion (version unknown). This issue affects an unknown function of the component RDS. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

ColdFusion RDS is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue does not require user interaction. Scope is changed. RDS is purely a development feature meant for debugging purposes, and switching ColdFusion to Production Secure Profile automatically disables RDS. The Lockdown Guide outlines the specific step to disable RDS if a ColdFusion server is not being used in Production Secure Profile.

The advisory is shared at adobe.com. The identification of this vulnerability is CVE-2026-90530 since 09/12/2026. The exploitation is known to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/14/2026). MITRE ATT&CK project uses the attack technique T1006 for this issue.
