CVE-2026-41605Network attack vector

Application disruption via Swift Compact Protocol overflow

Published Apr 28, 2026 · Updated Aug 26, 2026

Integer overflow in Apache Thrift's Swift Compact Protocol before 0.23.0 allows remote attackers to disrupt or corrupt applications. Apache's notice identifies the Swift Compact Protocol but does not disclose the affected function, arithmetic operation, or attacker-controlled value that wraps. Exposure requires an application to process attacker-controlled Compact Protocol data through the vulnerable Swift runtime; the wrap triggers resource exhaustion or unexpected behavior.
