netty-incubator-codec-ohttp: [OHttpServerCodec] Native Direct-Memory Leak on AEAD Decryption Failure Leads to Gateway Denial of Service
The netty-incubator-codec-ohttp library implements Oblivious HTTP OHTTP gateway and client functionality using Netty's ByteBuf memory management. When an OHTTP gateway processes encrypted client requests, it allocates a pooled direct native off-heap ByteBuf to hold the decrypted plaintext before...

Summary io.netty.incubator:netty-incubator-codec-bhttp can enter a non-terminating parse loop when a known-length Binary HTTP field section ends exactly after a complete field line. A remote peer that can send Binary HTTP input to a Netty pipeline using BinaryHttpParser / BinaryHttpDecoder can us...

Allocation of Resources Without Limits or Throttling
Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the handling of HTTP/1.1 pipelined requests over a single connection. An attacker can cause excessive memory consumption by sending multiple pipelined requests, potentially leading...
Use of Incorrectly-Resolved Name or Reference
Overview Affected versions of this package are vulnerable to Use of Incorrectly-Resolved Name or Reference in the process of handling DNS resolution when multiple clients with different DNS resolver configurations are dynamically created. An attacker can cause traffic to be routed to unintended...
Information Exposure
Overview Affected versions of this package are vulnerable to Information Exposure in the process handling HTTP requests when Brave Tracing is enabled. An attacker can obtain sensitive exception details from unrelated requests by sending crafted requests to the server. This is only exploitable if...
Open Redirect
Overview Affected versions of this package are vulnerable to Open Redirect in scenarios where a WebSocket handshake is redirected to a different origin and the HTTP client is explicitly configured to follow redirects. An attacker can obtain sensitive credentials by leveraging crafted redirect...
User Impersonation
Overview Affected versions of this package are vulnerable to User Impersonation in the evaluation of the remote IP address when the HAProxy Protocol is enabled. An attacker can bypass IP-based access controls by sending specially crafted requests. Note: This is only exploitable if the application...
