CVE-2026-34670

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 and earlier allows local users to crash applications. Adobe identifies malformed SDK input as the trigger but does not disclose the affected parser, input field, or incorrect validation operation. No privileges or user interaction are required, but the input must reach an application embedding the Rust or JavaScript SDK; the reported consequence is an application crash only.
