CVE-2026-34711Network attack vector

Unauthenticated application crash

Published Jun 9, 2026 · Updated Jun 9, 2026

Integer overflow in Adobe Content Credentials JS SDK 0.7.1 and earlier and Rust SDK 0.80.1 and earlier allows remote attackers to crash applications. Adobe has not published the affected function, arithmetic operation, or crafted-content property that triggers the integer wraparound. Unauthenticated network delivery requires no user interaction; successful exploitation interrupts only the embedding application's availability.
