Arbitrary file-system read via malicious file
Published Jun 9, 2026 · Updated Jun 9, 2026
Improper input validation in Adobe Dreamweaver 21.7 and earlier allows attackers to read arbitrary files after a victim opens a malicious file. Adobe has not disclosed the affected parser, file format, input field, or validation operation that permits access outside the intended scope. Exploitation requires local delivery and user interaction, and the resulting access is limited to filesystem confidentiality.
