AI risk analysis

Summary: The flaw allows authenticated attackers to crash SnailJob 1.7.0 servers by sending a specially crafted payload, leading to an OutOfMemoryError due to unbounded array allocation.
Exploitability: Exploitation requires authentication and knowledge of the Zstandard compression format; moderately difficult.
Blast radius: If exploited, it could result in server downtime affecting service availability for legitimate users.
Prioritized remediation: Upgrade to a patched version or disable retry tasks until a fix is available.

NVD 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.
