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 result in a Security feature bypass. An attacker could leverage this vulnerability to gain limited read and write access to unauthorized files or directories outside the intended restrictions. Exploitation of this issue does not require user interaction.
AnalysisAI
Path traversal in Adobe ColdFusion 2025.9 and 2023.20 (and earlier) allows unauthenticated remote attackers to bypass path restrictions and gain limited read and write access to files and directories outside the intended web root. The vulnerability is classified as a security feature bypass under CWE-22, exploitable over the network without user interaction. …

Vulnerability AssessmentAI
| Exploitation | No authentication is required - the CVSS vector PR:N confirms unauthenticated exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS score of 6.5 (Medium) reflects limited confidentiality and integrity impact (C:L/I:L) with no availability effect, which is consistent with partial file system access rather than full remote code execution. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a crafted HTTP request to a network-exposed ColdFusion endpoint, embedding encoded path traversal sequences (e.g., '%2e%2e%2f' or similar) in a filename or path parameter. ColdFusion's input validation fails to normalize the path, allowing the request to reference files outside the web root - for example, reading system configuration files containing credentials, or writing a file to a location that enables further compromise. … |
| Remediation | Apply the vendor-released patches detailed in Adobe Security Bulletin APSB26-68 (https://helpx.adobe.com/security/products/coldfusion/apsb26-68.html); consult that advisory for the specific fixed version numbers in the 2025 and 2023 release tracks, as exact patch versions were not included in the available intelligence data. … Detailed patch versions, workarounds, and compensating controls in full report. |
