CVE-2026-84747 Apache bRPC: Access Control Bypass via HTTP Request Paths Containing Empty Path Segments

Interpretation conflict in the HTTP protocol implementation in Apache bRPC version 1.18.0 on all platforms allows remote attackers to bypass access control rules enforced by a front proxy. Root Cause: The method dispatch function FindMethodPropertyByURI in bRPC's HTTP protocol splits the request...

CVE-2026-78058 Apache bRPC: Unbounded Resource Consumption and Crash in the HTTP/2 Receive Path

Uncontrolled resource consumption in the HTTP/2 h2 receive path of Apache bRPC version 1.18.0 on all platforms allows a remote unauthenticated attacker to crash the server or grow its memory without bound by sending crafted HTTP/2 frames. Root Cause: The h2 parser, enabled by default on every bRP...

Uncontrolled resource consumption in the HTTP/2 h2 receive path of Apache bRPC version 1.18.0 on all platforms allows a remote unauthenticated attacker to crash the server or grow its memory without bound by sending crafted HTTP/2 frames. Root Cause: The h2 parser, enabled by default on every bRP...

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-2026-78048

Apache bRPC versions prior to 1.18.0 are vulnerable to a Remote Denial of Service (DoS) via a reachable-assertion flaw in the HPACK header-compression decoder of the HTTP/2 (h2/gRPC) stack. The root cause is located in src/brpc/details/hpack.cpp, where the IndexTable::Init function incorrectly as...

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 +...

Exposure Of Sensitive Information

A2A Java SDK is vulnerable to Exposure of Sensitive Information. The vulnerability is due to improper redirect handling in the Android HTTP client's synchronous POST requests, which allows an attacker controlling a redirected destination to obtain configured API keys or authentication tokens...

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...

EUVD-2026-107176

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 and denial of service because they do not consistently enforce 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 tri...

CVE-2026-56386 Apache bRPC: Integer Underflow and Out-of-Bounds Read in HTTP/2 DATA Frame Parser

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-2026-56386 Apache bRPC: Integer Underflow and Out-of-Bounds Read in HTTP/2 DATA Frame Parser

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...

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-2026-56386

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...

nghttp2: nghttp2: HTTP Request/Response Smuggling and Response-Queue Poisoning via ambiguous HTTP/1.1 Upgrade requests

A flaw in nghttp2's nghttpx proxy allows a remote attacker to perform HTTP request smuggling and cross-client response-queue poisoning. This occurs because the proxy ambiguously forwards HTTP/1.1 Upgrade requests that contain a Content-Length header to reusable keep-alive backend connections...

CVE-2026-54425 Apache bRPC: Stack Exhaustion via Recursive HPACK Dynamic Table Size Update Decoding

Uncontrolled recursion in the HTTP/2 HPACK decoder in Apache bRPC before 1.18.0 allows remote attackers to cause denial of service by sending a crafted HTTP/2 header block containing many consecutive Dynamic Table Size Update entries. Each update was decoded by recursively invoking the HPACK...

CVE-2026-54425

Apache bRPC versions before 1.18.0 are vulnerable to a denial of service (DoS) due to uncontrolled recursion (CWE-674) in the HTTP/2 HPACK decoder. An attacker can send a crafted HTTP/2 header block with many consecutive Dynamic Table Size Update entries, causing the decoder to exhaust the thread...
