Application denial-of-service via undisclosed resource exhaustion
Published Sep 22, 2026 · Updated Sep 22, 2026
Resource exhaustion in Adobe c2pa 0.89.2 and earlier and c2patool 0.26.70 and earlier allows attackers to interrupt applications. Adobe has not published the affected parser or operation, the crafted input format, or which resource grows without a bound. Exploitation requires no user interaction and can exhaust host resources until the integrating application or command-line process becomes unavailable.
