Adobe ColdFusion: Incorrect authorization allows code execution via crafted file
Summary
Adobe ColdFusion 2023 and 2025 contain an Incorrect Authorization flaw (CWE-863). An authenticated low-privileged user can execute arbitrary code in the context of the current user, and the impact can extend beyond the vulnerable component because the scope is changed. Exploitation requires a victim to open a malicious file, so it is a local attack that is not directly reachable from the internet.
Affected
- Adobe ColdFusion 2025 up to and including 2025.0.13
- Adobe ColdFusion 2023 up to and including 2023.0.25
Fixed in
- Adobe ColdFusion 2025 Update 14 (2025.0.14)
- Adobe ColdFusion 2023 Update 26 (2023.0.26)
Workaround
Unknown.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in this update.
- CISA SSVC assessment: exploitation none, not automatable.
- Not listed in CISA KEV at the time of research.
Our recommendation
- Identify all ColdFusion 2023 and 2025 instances and their versions.
- Test and then install the fixed releases 2023 Update 26 or 2025 Update 14 as soon as possible, since the update also contains other critical and high-rated issues.
- Review the configuration changes in Update 26 after patching.
- Limit local logon and file upload paths on servers, and restrict low-privileged accounts to the minimum needed.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
