Netty: TOCTOU in OcspServerCertificateValidator
Summary Netty's OcspServerCertificateValidator forwards the SslHandshakeCompletionEvent before the asynchronous OCSP validation completes. This allows the client's downstream handlers to send sensitive application data e.g., HTTP requests to a revoked server before the channel is closed by the OC...

Time-of-check Time-of-use (TOCTOU) Race Condition
Overview io.netty:netty-handler-ssl-ocsp is a Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers and clients. Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Conditio...
GHSA-G7HG-VRCF-MVMR Netty: Out-of-date OCSP Responses Accepted by OcspServerCertificateValidator
Summary OcspServerCertificateValidator flags an out-of-date OCSP response but does not stop processing it, so an expired GOOD response is still reported as VALID, letting an on-path attacker replay a stale GOOD response to bypass revocation of a since-revoked certificate. Details In...
Improper Check for Certificate Revocation

Affected versions of this package are vulnerable to Improper Check for Certificate Revocation in t...
Netty: Missing CertificateID Validation in OCSP Response Allows Replay Attacks
Summary Netty's OcspClient does not validate that the CertificateID in an OCSP response matches the requested CertificateID. A bad actor can replay a GOOD status response issued for an unrelated certificate by the same CA to bypass revocation checks for any certificate. Details...

GHSA-4QHR-G3C6-FCFX Netty XML: Injection / Risky Sink — unconfigured XML factory with active DTD and entity handling
Any caller that can deliver bytes to a Netty channel pipeline containing XmlDecoder can send XML with a DOCTYPE declaration to a parser instantiated with no security configuration — but whether external entities are actually resolved depends on Aalto XML's async parser behavior, making this a...

GHSA-HPCC-26XQ-25FV Netty: Memory Exhaustion via HTTP/3 Reserved Frame Types
Summary Netty's Http3FrameCodec buffers incoming data for HTTP/3 reserved frame types up to the specified payload length without any limits. The payload length is read directly from the wire and trusted without validation. A bad actor can send a reserved frame with a payload length of up to...

GHSA-6CQP-G7GG-8HR5 Netty: Security Control Bypass via CORS Short-Circuit Failure
Summary Netty's CorsHandler provides a shortCircuit configuration designed to reject unauthorized cross-origin requests immediately, acting as a security control before requests reach the application. However, due to a logical operator error in the origin evaluation process, this protection can b...
GHSA-JPPX-W49H-X2QQ Netty: [SpdyHttpDecoder] ByteBuf Reference Leak on RST_STREAM Leads to Native Memory Exhaustion
The SpdyHttpDecoder handler in Netty's SPDY-to-HTTP codec allocates a pooled ByteBuf when processing a client-initiated SYNSTREAM frame with FLAGFIN=0, storing the partially-constructed FullHttpRequest in an internal map messageMap to accumulate subsequent DATA frames. When the remote peer sends ...

GHSA-Q6CQ-MHR2-JMR5 Netty: [codec-haproxy] Signed-Byte Sentinel Collision in HAProxyMessageDecoder Leads to Unbounded Memory Exhaustion
The HAProxyMessageDecoder in netty's codec-haproxy module performs protocol version detection by reading the 13th byte of the inbound stream as a signed Java byte and widening it to int without masking. When an attacker sends a PROXY protocol v2 binary prefix 0D 0A 0D 0A 00 0D 0A 51 55 49 54 0A...
