Published: 2026-06-10 · Severity: routine
Canonical: https://vorant.io/reports/36a7a28f-7352-5178-959c-8ac6b5896a7c/multiple-vulnerabilities-in-adobe-acrobat-and-coldfusion

> Multiple vulnerabilities in Adobe Acrobat, Reader, and ColdFusion allow remote code execution, privilege escalation, and data theft.

CERT-FR has released a security advisory documenting multiple vulnerabilities across Adobe's product line. Affected products include Acrobat 2024 (before version 24.001.30383), Acrobat Reader (before 26.001.21662), Adobe Acrobat (before 26.001.21662) for both Windows and macOS, ColdFusion 2023 (before Update 20), and ColdFusion 2025 (before Update 9). The vulnerabilities enable remote code execution, privilege escalation, confidentiality breaches, security policy bypass, denial of service, and XSS injection. Defenders should apply the patches referenced in Adobe security bulletins APSB26-63 and APSB26-64 immediately to affected systems.

## Detection guidance (public sample)

### Adobe Acrobat or Reader Spawning Shell or Script Interpreter

ATT&CK: T1203

Acrobat/Reader launching cmd, PowerShell, script hosts or LOLBins, a typical post-exploitation pattern after a client-side RCE in a malicious PDF. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

```yaml
title: Adobe Acrobat or Reader Spawning Shell or Script Interpreter
id: 4b6286ae-faf1-5475-b005-44aeeea09336
status: experimental
description: Detects Adobe Acrobat or Reader spawning command shells, script hosts
  or common living-off-the-land binaries. This is a typical post-exploitation pattern
  after exploitation of a code execution flaw in the PDF reader (e.g. the Acrobat
  vulnerabilities in APSB26-63). Matches on the parent/child relation, not on specific
  payloads.

### ColdFusion Server Process Spawning Shell or Recon Utility

ATT&CK: T1190

The ColdFusion service process spawning cmd, PowerShell or common recon/download utilities, indicating possible web-facing RCE exploitation. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

```yaml
title: ColdFusion Server Process Spawning Shell or Recon Utility
id: 43f9792a-fce7-5dbf-b95d-4b11b1c41a3f
status: experimental
description: Detects the Adobe ColdFusion server process (coldfusion.exe or its bundled
  java.exe) spawning command shells or common recon and download utilities. This indicates
  possible exploitation of a remote code execution flaw in ColdFusion (e.g. APSB26-64).
  Matches on the parent/child relation, not on specific payloads.
