Code execution via malicious file command injection
Published Jan 13, 2026 · Updated Jan 13, 2026
OS command injection in Adobe Dreamweaver 21.6 and earlier allows attackers to execute arbitrary code through a malicious file. Adobe has not disclosed the affected parser, command-construction path, or which untrusted file elements reach an operating-system command. Exploitation requires a victim to open the file, after which commands execute in a changed security scope with the application's effective access.
