## Description

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 lead to arbitrary file system read and limited write access. 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.

## CrowdSec analysis

[CVE-2026-48313](https://euvd.enisa.europa.eu/vulnerability/CVE-2026-48313) is a critical path traversal vulnerability in Adobe ColdFusion versions 2025.9, 2023.20, and earlier, allowing unauthenticated remote attackers to bypass directory restrictions and read arbitrary files. The flaw may also provide limited write access to the file system without requiring user interaction, potentially exposing sensitive data and enabling further compromise of connected systems.

CrowdSec has been tracking this vulnerability and its exploits since 23rd of July 2026.

Insights from the CrowdSec network reveal that the attackers trying to exploit CVE-2026-48313 are composed of a fairly even mix of opportunistic and targeted actors. Some attackers employ preliminary reconnaissance, while others use indiscriminate scanning.
CrowdSec data also reveals a clear uptick in attacks involving CVE-2026-48313 over the past week. Activity is above the usual baseline, suggesting growing attention from attackers. This may reflect rising awareness, recent exploit releases, or expanded targeting efforts.

Attackers target the ColdFusion endpoint `/CFIDE/main/ide.cfm` with `ACTION=FILEIO`, submitting serialized `READ` requests to access files outside the intended directory. Common indicators include requests for `/etc/passwd` or `C:\Windows\win.ini` and responses containing Unix account data or the `[fonts]` section.
