CVE-2026-34666

Local application crash

Published May 12, 2026 · Updated May 12, 2026

Improper input validation in Adobe Content Credentials SDK 0.78.2 and 0.7.0 allows local users to crash applications via crafted data. Adobe identifies the affected component only at the SDK level and has not disclosed the specific parser, input field, or validation operation that mishandles the data. Exploitation requires local access but no privileges or user interaction, and the documented consequence is limited to terminating an application that processes the input.
