CVE-2026-53994

ProFTPD mod_sftp has a heap-based buffer overflow reachable by an authenticated SFTP user. The fxp_packet_read() function accepts an attacker-controlled 32-bit big-endian SFTP packet length without minimum sanity checks. A value of 0 underflows in the read path, yielding an oversized request (~4 ...

Open Web Analytics 1.7.3 - Remote Code Execution

Open Web Analytics OWA before 1.7.4 allows an unauthenticated remote attacker to obtain sensitive user information, which can be used to gain admin privileges by leveraging cache hashes. This occurs because files generated with '?php instead of the intended "?php sequence aren't handled by the PH...

Name of the Vulnerable Software and Affected Versions ProFTPD mod sftp affected versions not specified Description An authenticated SFTP user can trigger a heap-based buffer overflow. The fxp packet read function fails to perform a minimum sanity check on the attacker-supplied 32-bit big-endian...

CVE-2026-47183 Zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.6, DNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dictionary keyed by attacker-influenced IncomingDecodeError messages, retaining sys.excinfo...

CVE-2026-47183

CVE-2026-47183 - zeroconf (python-zeroconf) : Affected versions prior to 0.149.6 store an unbounded in-memory log of exceptions in DNSIncoming._log_exception_debug and QuietLogger dedup, retaining frame locals with raw packet data. This enables any unauthenticated LAN host on UDP/5353 (224.0.0.25...

CVE-2026-33754

Wazuh 3.9.0+ is affected by an unauthenticated DoS in the cluster protocol parser caused by a crafted header with an arbitrarily large payload length. The vulnerability arises because the length is trusted before authentication/decryption and used to allocate memory, leading to memory exhaustion ...

CVE-2026-44435

Quicly is an IETF QUIC protocol implementation intended primarily for use within the H2O HTTP server. Prior to commit 937d0e9, an assertion failure is raised when the total number of valid handshake messages received over a CRYPTO stream of a single packet number space exceeds 32KB, causing a...

CVE-2026-15422 SCTP needs to better-check INIT ACK chunk parameters

The illumos SCTP inbound path performs association lookup for INIT ACK chunks without adequately validating the address parameters carried in the chunk. Since this lookup runs during packet classification i.e. before SCTP integrity checks or IPsec policy are applied a remote, unauthenticated...

CVE-2026-55548

In Yamcs, CVE-2026-55548 affects the PacketsApi.exportPackets endpoint. The root cause was failure to enforce per-packet ReadPacket privileges when a request supplied an empty packet-name list, causing no WHERE pname IN filter and the onTuple handler to stream packets without per-row authorizatio...
