CVE-2026-55204

A flaw was found in HAProxy. An attacker can trigger HPACK dynamic table insertions under memory pressure, leading to a null pointer dereference in the hpackdhtinsert function. This can cause HAProxy worker processes to crash, resulting in a denial of service DoS. Mitigation Mitigation for this...

BIT-HAPROXY-2026-55204 HAProxy - NULL Pointer Dereference in hpack_dht_insert Function

HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpackdhtinsert within src/hpack-tbl.c that fails to validate the return value of hpackdhtdefrag when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memo...

JLSEC-2026-624 HTTP/2 client HPACK desynchronization via header blocks for unknown streams in HTTP.jl

Description The HTTP/2 client's processincomingframe! dropped HEADERS/CONTINUATION frames for stream ids absent from conn.streams without passing the header block through the connection's HPACK decoder. Because HPACK's dynamic table is connection-scoped and mutated as a side effect of decoding ea...
