Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-42587)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in HttpContentDecompressor and DelegatingDecompressorFrameListener when processing compressed HTTP request bodies with Content-Encoding set to br, zstd, or snappy. A remote attacker can send a specially crafted compressed payload to cause a denial of service.

The configured maxAllocation limit is enforced for gzip and deflate, but is silently ignored for brotli, zstd, and snappy. The issue affects both HTTP/1.1 and HTTP/2 handling.
