Path Traversal Arbitrary File Read in Adobe ColdFusion

IdentifiersCVE-2026-48313CWE-22

CVE-2026-48313 is a path traversal vulnerability in Adobe ColdFusion caused by improper limitation of a pathname to a restricted directory. It affects ColdFusion 2025.9, 2023.20, and earlier versions. A remote attacker can exploit the flaw to access files and directories outside the intended access scope, resulting in arbitrary file system read and limited write access. The issue does not require user interaction and is described as remotely exploitable.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can expose sensitive files and directories outside the intended restricted path, including configuration data and potentially credentials or other secrets stored on the server. The vulnerability also allows limited file write access, which increases integrity risk beyond disclosure alone. The provided context states the CVSS 3.1 base score is 9.3 with scope changed, and notes high confidentiality, integrity, and availability impact.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict ColdFusion access to sensitive files and directories as much as operationally feasible, monitor for unauthorized file system access attempts, and apply Adobe’s ColdFusion hardening guidance. The provided advisory context also recommends using the latest supported JDK/JRE LTS release, the latest MySQL Java connector, applying ColdFusion security configuration and Lockdown Guide recommendations, and for JEE deployments configuring the documented JVM serial filter option.

Remediation

Patch, then assume compromise.

Upgrade Adobe ColdFusion 2025 to Update 10 and Adobe ColdFusion 2023 to Update 21. More generally, update to a version newer than 2025.9 and 2023.20, as those versions and earlier are affected. Adobe strongly recommends applying the vendor security update as soon as possible.
