SnailJob 1.7.0 Denial of Service via FuryUtil.deserialize OOM

State: Published
Severity: 7.1 High
Published: Aug 4, 2026
Updated: Sep 24, 2026
Reserved: Aug 3, 2026

Description

SnailJob 1.7.0 contains a denial of service vulnerability in the FuryUtil.deserialize helper that allows authenticated attackers to crash the server by supplying a crafted Zstandard-compressed payload with an inflated frame_content_size field in the frame header. Attackers can store a base64-encoded Zstandard payload declaring an arbitrarily large decompressed size in a retry task argument, causing the JVM to attempt an unbounded array allocation and triggering an unrecoverable java.lang.OutOfMemoryError when the task is dispatched through the retry-task pipeline.
