Official description
ColdFusion versions 2025.2, 2023.14, 2021.20 and earlier are affected by an XML Injection vulnerability that could lead to arbitrary file system read. An attacker can exploit this issue by injecting crafted XML or XPath queries to access unauthorized files or lead to denial of service. Exploitation of this issue does not require user interaction, and attack must have access to shared secrets.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: XML Injection
The product does not properly neutralize special elements that are used in XML, allowing attackers to modify the syntax, content, or commands of the XML before it is processed by an end system.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
