CVE-2026-69702: Memory Allocation with Excessive Size Value in aizuda SnailJob (snail-job)
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.
AI Analysis
Technical Summary
CVE-2026-69702 is a denial of service vulnerability in aizuda's SnailJob 1.7.0. The flaw exists in the FuryUtil.deserialize helper, which processes Zstandard-compressed payloads. An attacker with authentication can craft a payload with an inflated frame_content_size in the frame header, causing the JVM to allocate an excessively large array. This leads to an unrecoverable java.lang.OutOfMemoryError when the task is dispatched through the retry-task pipeline, crashing the server.
Potential Impact
Successful exploitation results in a denial of service by crashing the server due to an unrecoverable OutOfMemoryError in the JVM. This disrupts normal operations of SnailJob 1.7.0, potentially causing service outages.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict authenticated user access to trusted parties and monitor for suspicious retry task payloads.
