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...

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...

Uncontrolled recursion in the AMF parser in Apache bRPC 1.18.0 allows a remote RTMP peer to crash a bRPC process by sending deeply nested AMF objects or arrays. The parser recursively processed nested AMF containers without enforcing a depth limit, which could exhaust the native stack. Affected...

CVE-2026-54427

Apache bRPC versions prior to 1.18.0 are vulnerable to a stack exhaustion attack due to uncontrolled recursion in the AMF parser. The parser fails to enforce a depth limit when processing nested AMF containers, allowing a remote RTMP peer to crash the bRPC process by sending deeply nested AMF obj...

CVE-2026-54427 Apache bRPC: Stack Exhaustion via Unbounded Recursion in AMF Parser

Uncontrolled recursion in the AMF parser in Apache bRPC 1.18.0 allows a remote RTMP peer to crash a bRPC process by sending deeply nested AMF objects or arrays. The parser recursively processed nested AMF containers without enforcing a depth limit, which could exhaust the native stack. Affected...

CVE-2026-54426

Versions of Apache bRPC prior to 1.18.0 are vulnerable to a crash due to uncontrolled recursion in the Redis reply parser. A remote Redis server peer can trigger this by returning a deeply nested RESP array reply , causing the bRPC Redis client process to crash because the parser lacks a depth li...

EUVD-2026-107170

Uncontrolled recursion in the Redis reply parser in Apache bRPC 1.18.0 allows a remote Redis server peer to crash a bRPC Redis client process by returning a deeply nested RESP array reply. The parser recursed once for each nested array level without enforcing a depth limit. The fix adds a...

CVE-2026-54426 Apache bRPC: Stack Exhaustion via Unbounded Recursion in Redis Reply Parser

Uncontrolled recursion in the Redis reply parser in Apache bRPC 1.18.0 allows a remote Redis server peer to crash a bRPC Redis client process by returning a deeply nested RESP array reply. The parser recursed once for each nested array level without enforcing a depth limit. The fix adds a...

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...

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...

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...

EUVD-2026-107168

Improper authentication in Apache bRPC through 1.17.0 allows a remote unauthenticated attacker to bypass authentication for protected non-builtin HTTP endpoints by first sending a builtin HTTP request on the same HTTP/1.1 keep-alive connection. When ServerOptions.auth is enabled and builtin HTTP...

CVE-2026-48830 Apache bRPC: HTTP builtin request can mark a connection authenticated and bypass auth for later requests

Improper authentication in Apache bRPC through 1.17.0 allows a remote unauthenticated attacker to bypass authentication for protected non-builtin HTTP endpoints by first sending a builtin HTTP request on the same HTTP/1.1 keep-alive connection. When ServerOptions.auth is enabled and builtin HTTP...

CVE-2026-48830

Apache bRPC versions through 1.17.0 are vulnerable to an improper authentication issue. When ServerOptions.auth is enabled and builtin HTTP services are exposed on the public listener, a remote unauthenticated attacker can bypass authentication for protected non-builtin HTTP endpoints. This is ac...

Apache bRPC resource management error vulnerability

Versions of Apache bRPC prior to 1.18.0 contain a resource management error vulnerability. This vulnerability arises because Redis’s inline command parsing allocates memory and copies the entire input buffer based on its current size before determining the command boundary; there is no proper lim...

PT-2026-120561

A data race in the RDMA transport of Apache bRPC versions 1.18.0 allows a remote client to crash the server process denial of service when RDMA is enabled at build time and runtime. Root Cause: When a bRPC server negotiates RDMA with a client, the handshake completes on the TCP fd, but the server...

PT-2026-120534

The Redis protocol implementation in Apache bRPC allowed inline command parsing to allocate and copy the full connection buffer before a complete CRLF-terminated command was available. A remote attacker with access to a Redis-protocol bRPC service could send long inline inputs without a terminati...
