CVE-2026-54428 (GCVE-0-2026-54428)

Vulnerability from cvelistv5 – Published: 2026-07-01 17:03 – Updated: 2026-07-01 18:15

Title

Apache HttpComponents Core: HPackDecoder Unlimited Header List Size Before SETTINGS ACK

Summary

Allocation of resources without limits or throttling in the HTTP/2 HPACK decoder in Apache HttpComponents Core (5.4.2 and earlier, 5.5-beta1 and earlier) allows an remote attacker to cause a denial of service through memory exhaustion by sending oversized compressed header blocks before the HTTP/2 SETTINGS acknowledgement causes the configured header list size limit to be applied.

Severity

7.5 (High)
