NewCVE-2026-90559 (opens in a new tab)How to fix?
There is no fixed version for org.xerial.snappy:snappy-java.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Write via the Snappy.uncompress(ByteBuffer, ByteBuffer) method in org/xerial/snappy/Snappy.java. An attacker can trigger JVM termination by supplying valid compressed input that expands beyond the destination ByteBuffer capacity. The vulnerable code does not validate the output buffer size against the decompressed size, so writes past the buffer boundary occur during decompression, crashing applications that process attacker-controlled Snappy data.
