CVE-2026-78048 Apache bRPC: Remote Denial of Service via Out-of-Bounds Dynamic Table Sizing in HPACK Decoder

A reachable-assertion flaw in the HPACK header-compression decoder of the HTTP/2 h2/gRPC stack in Apache bRPC version = 1 byte + value = 1 byte + 32 bytes of overhead. However, RFC 7541 section 4.1 specifies that the minimum entry size is 33 bytes, because the value may be empty name = 1 byte +...

CVE-2026-61902 Apache bRPC: Memory Exhaustion Through Inconsistent Message Body Limits

Apache bRPC versions before 1.18.0 do not consistently enforce the configured maxbodysize limit in non-progressive HTTP/1 and HTTP/2 parsing and in memcache and couchbase response parsing. A remote unauthenticated peer can cause an affected process to buffer message data beyond the configured...

CVE-2026-61902

Apache bRPC versions before 1.18.0 are vulnerable to memory exhaustion due to inconsistent enforcement of the max_body_size limit during non-progressive HTTP/1 and HTTP/2 parsing, as well as memcache and couchbase response parsing. A remote unauthenticated peer can exploit this to buffer message ...

CVE-2026-56386

The Apache bRPC HTTP/2 server DATA frame parser is vulnerable to an integer underflow and out-of-bounds read . The issue arises because the handler decrements the fragment size when the PADDED flag is set before verifying the presence of the mandatory pad length byte. An unauthenticated remote at...

EUVD-2026-107172

Integer underflow and out-of-bounds read in the HTTP/2 server DATA frame parser in Apache bRPC allows an unauthenticated remote attacker to cause denial of service by sending a malformed DATA frame with the PADDED flag set and a zero-length payload. Root Cause: The HTTP/2 DATA frame handler...

CVE-2026-54425

Apache bRPC versions before 1.18.0 are vulnerable to a denial of service (DoS) attack due to uncontrolled recursion in the HTTP/2 HPACK decoder. A remote attacker can trigger this by sending a crafted HTTP/2 header block with numerous consecutive Dynamic Table Size Update entries. Because the dec...
