CVE-2026-43820

NIOSSLCertificate.subjectAlternativeNames provides access to the raw bytes for a cert's SANs. NIOSSL provides access to a buffer assumed to be backed by an ASN1STRING, but not all SANs are backed by ASN1STRING, so accessing the buffer for such a type can lead to out-of-bounds memory access. This...

CVE-2026-43820

The CVE-2026-43820 vulnerability affects the NIOSSL component used with SwiftNIO SSL. NIOSSLCertificate._subjectAlternativeNames exposes the raw bytes of a certificate’s SANs; NIOSSL may expose a buffer expected to be backed by an ASN1_STRING, but not all SAN types are backed accordingly, which c...

PYSEC-2026-842 When matrix-nio receives forwarded room keys, the receiver doesn't check if it requested the key from the forwarder

When matrix-nio before 0.20 requests a room key from our devices, it correctly accepts key forwards only if they are a response to a previous request. However, it doesn't check that the device that responded matches the device the key was requested from. This allows a malicious homeserver to inse...

CVE-2026-53916

Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp. An unauthenticated client that opens a STOMP NIO connection can send header bytes that never terminate which makes the broker buffer them without limit, exhausting the JVM hea...

CVE-2026-53916 Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp: Unbounded header buffer in STOMP NIO codec

Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp. An unauthenticated client that opens a STOMP NIO connection can send header bytes that never terminate which makes the broker buffer them without limit, exhausting the JVM hea...

CVE-2026-53916

CVE-2026-53916 describes a memory allocation issue in Apache ActiveMQ families (ActiveMQ, ActiveMQ All, ActiveMQ Stomp) caused by an unauthenticated STOMP NIO client that can emit header bytes that never terminate. This unbounded header buffering can exhaust the JVM heap. Affected versions are be...

GHSA-6PH5-FWW6-VFWV NIOExtras: NIOHTTPRequestDecompressor ratio limit bypass via inflated Content-Length

Impact When NIOHTTPRequestDecompressor is configured with .ratioN, the decompression limit is enforced using the Content-Length header value from the incoming request rather than the actual number of compressed bytes received. Since Content-Length is attacker-controlled, a malicious client can...

SwiftNIO NIOHTTP1: HTTPDecoder accepts unbounded HTTP/1 header blocks, enabling remote DoS

Summary The HTTPDecoder in NIOHTTP1 enforces no limit on the total size of an HTTP/1 message's header block or on the number of header fields per message. A remote peer can submit an arbitrary number of small, valid headers in a single request and have them all accumulated into the resulting...
