CVE-2026-69702Network attack vector

Authenticated server crash via unbounded decompression allocation

Published Aug 4, 2026 · Updated Aug 4, 2026

Denial of service in Aizuda SnailJob 1.7.0 allows remote authenticated users to crash the server through a crafted retry argument. FuryUtil.deserialize trusts the Zstandard frame_content_size value and allocates a decompression array without enforcing a size limit. An authenticated user must store the encoded payload in a retry task; dispatch then exhausts JVM memory and terminates the server.
