CVE-2022-20854 1 Cisco 2 Secure Firewall Management Center, Secure Firewall Threat Defense 2026-08-11 7.5 High
A vulnerability in the processing of SSH connections of Cisco Firepower Management Center (FMC) and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper error handling when an SSH session fails to be established. An attacker could exploit this vulnerability by sending a high rate of crafted SSH connections to the instance. A successful exploit could allow the attacker to cause resource exhaustion, resulting in a reboot on the affected device.
CVE-2018-0230 1 Cisco 2 Adaptive Security Appliance Software, Secure Firewall Threat Defense 2026-08-11 N/A
A vulnerability in the internal packet-processing functionality of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Security Appliances could allow an unauthenticated, remote attacker to cause an affected device to stop processing traffic, resulting in a denial of service (DoS) condition. The vulnerability is due to the affected software improperly validating IP Version 4 (IPv4) and IP Version 6 (IPv6) packets after the software reassembles the packets (following IP Fragmentation). An attacker could exploit this vulnerability by sending a series of malicious, fragmented IPv4 or IPv6 packets to an affected device. A successful exploit could allow the attacker to cause Snort processes on the affected device to hang at 100% CPU utilization, which could cause the device to stop processing traffic and result in a DoS condition until the device is reloaded manually. This vulnerability affects Cisco Firepower Threat Defense (FTD) Software Releases 6.2.1 and 6.2.2, if the software is running on a Cisco Firepower 2100 Series Security Appliance. Cisco Bug IDs: CSCvf91098.
CVE-2017-6632 1 Cisco 2 Firepower Threat Defense, Secure Firewall Threat Defense 2026-08-11 N/A
A vulnerability in the logging configuration of Secure Sockets Layer (SSL) policies for Cisco FirePOWER System Software 5.3.0 through 6.2.2 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to high consumption of system resources. The vulnerability is due to the logging of certain TCP packets by the affected software. An attacker could exploit this vulnerability by sending a flood of crafted TCP packets to an affected device. A successful exploit could allow the attacker to cause a DoS condition. The success of an exploit is dependent on how an administrator has configured logging for SSL policies for a device. This vulnerability affects Cisco FirePOWER System Software that is configured to log connections by using SSL policy default actions. Cisco Bug IDs: CSCvd07072.
CVE-2026-65819 1 Gopacket 1 Gopacket 2026-08-11 7.5 High
gopacket provides packet processing capabilities for Go. Through version 1.7.0, multiple layer decoders use attacker-controlled lengths, counts, or offsets before validating them against packet buffers, allowing a crafted packet decoded through DecodingLayerParser or DecodeFromBytes to trigger an unrecovered panic and remotely deny service. A patch commit is available at 210f25f.
CVE-2026-52880 1 Klever-io 1 Klever-go 2026-08-11 7.5 High
Klever-Go is the Go implementation of the Klever blockchain protocol. Versions from 1.7.14 through 1.7.17 are vulnerable to a remotely triggerable denial of service. Both REST APIs are started with the Gin Engine.Run convenience method, which serves requests through Go's default HTTP server with no ReadHeaderTimeout, ReadTimeout, or MaxHeaderBytes configured. As a result, incoming connections that never complete their request headers are held open indefinitely. When a REST listener is reachable beyond localhost through the documented all-interface bind or a Docker port-publish deployment, a single unauthenticated client can open many slow-header connections and hold them open until server file descriptors are exhausted, preventing the API from accepting new connections. This renders the REST API unavailable to legitimate clients. This issue is fixed in version 1.7.18.
CVE-2026-18464 2 Wordpress, Wp Maps Pro 2 Wordpress, Wp Maps Pro 2026-08-10 7.5 High
The WP MAPS PRO WordPress plugin before 6.1.3 does not perform a capability check in one of its AJAX actions, which is also available to unauthenticated users, and does not restrict the operation it dispatches, allowing unauthenticated attackers to trigger uncontrolled recursion that exhausts server resources, resulting in a Denial of Service.
CVE-2026-52879 1 Klever-io 1 Klever-go 2026-08-10 7.5 High
Klever-Go is the Go implementation of the Klever blockchain protocol. In versions 1.7.14 through 1.7.17, the direct-message ingress handler spawns a new goroutine for every incoming direct message before the processor-level antiflood layer makes any admission decision, with no semaphore, throttler, or bound on the number of concurrent in-flight spawns. Because the antiflood check runs inside the spawned goroutine rather than before it, a single connected peer can open a direct-send stream and send a stream of well-formed messages to force unbounded goroutine creation, where each goroutine allocates its own stack and holds a message reference until processing completes, adding scheduler and garbage-collection pressure faster than the runtime can drain it. This lets one peer degrade the node's availability and its ability to process legitimate traffic, resulting in a remotely triggerable denial of service. The issue is fixed in 1.7.18.
CVE-2026-71870 1 Py-pdf 1 Pypdf 2026-08-10 5.5 Medium
pypdf is a free and open-source pure-python PDF library. Prior to 6.15.0, a crafted PDF can cause large memory consumption when pypdf/_cmap.py function parse_bfrange parses unusually large source-code or destination-string tokens in a font /ToUnicode CMap during text extraction. This issue is fixed in 6.15.0.
CVE-2026-16265 2 Wordpress, Wp Maps 2 Wordpress, Wp Maps 2026-08-07 6.5 Medium
The WP Maps WordPress plugin before 4.9.7 does not perform a capability check in one of its AJAX actions and does not restrict the operation it dispatches, allowing users with a Subscriber account to trigger uncontrolled recursion that exhausts server resources, resulting in a Denial of Service.
CVE-2026-46273 1 Linux 1 Linux Kernel 2026-08-07 8.6 High
In the Linux kernel, the following vulnerability has been resolved: ibmveth: Disable GSO for packets with small MSS Some physical adapters on Power systems do not support segmentation offload when the MSS is less than 224 bytes. Attempting to send such packets causes the adapter to freeze, stopping all traffic until manually reset. Implement ndo_features_check to disable GSO for packets with small MSS values. The network stack will perform software segmentation instead. The 224-byte minimum matches ibmvnic commit <f10b09ef687f> ("ibmvnic: Enforce stronger sanity checks on GSO packets") which uses the same physical adapters in SEA configurations. The issue occurs specifically when the hardware attempts to perform segmentation (gso_segs > 1) with a small MSS. Single-segment GSO packets (gso_segs == 1) do not trigger the problematic LSO code path and are transmitted normally without segmentation. Add an ndo_features_check callback to disable GSO when MSS < 224 bytes. Also call vlan_features_check() to ensure proper handling of VLAN packets, particularly QinQ (802.1ad) configurations where the hardware parser may not support certain offload features. Validated using iptables to force small MSS values. Without the fix, the adapter freezes. With the fix, packets are segmented in software and transmission succeeds. Comprehensive regression testing completedd (MSS tests, performance, stability).
CVE-2026-64958 1 Apache 1 Cxf 2026-08-07 7.5 High
An incomplete fix for CVE-2026-50645 means that it is still possible to perform a denial of service attack on Apache CXF by sending a message with many attachment headers. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue.
CVE-2026-58627 1 Microsoft 14 Windows 10 1607, Windows 10 1809, Windows Server 2012 and 11 more 2026-08-07 7.5 High
Uncontrolled resource consumption in Windows DHCP Server allows an unauthorized attacker to deny service over a network.
CVE-2026-58045 1 Nodejs 1 Nodejs 2026-08-07 6.2 Medium
A flaw in Node.js allows a spoofed `TypedArray` `byteLength` to trigger a reachable assertion in the synchronous `node:zlib` APIs, causing the entire process to crash. All 11 synchronous zlib functions are affected. Repeated exploitation of this condition can result in a denial of service. This vulnerability affects Node.js **22.x**, **24.x**, and **26.x**.
CVE-2026-56846 2 Nodejs, Redhat 2 Nodejs, Hummingbird 2026-08-07 7.5 High

CVE-2026-58042 1 Nodejs 1 Nodejs 2026-08-07 5.9 Medium
A flaw in Node.js can cause dns.resolveAny() Aborts the Node.js Process When a DNS Response Contains More Than 256 A Records. Repeated triggering of this condition can lead to denial of service. This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.
CVE-2026-67864 1 Open62541 1 Open62541 2026-08-06 7.5 High
An issue in open62541 v.1.5.5 and before allows a remote attacker to cause a denial of service via the NodeManagement type-instantiation logic component
CVE-2026-57819 1 Apache 1 Cxf 2026-08-06 7.5 High
Apache CXF allows to set a limit on the number of form parameters in a JAX-RS message via the "maxFormParameterCount" configuration option. However, no default limit is set which may lead to denial of service attacks when processing  requests with very large numbers of form parameters. Users are recommended to upgrade to versions 4.2.3 or 4.1.8 or 3.6.12, which fix this issue by using a default limit of 500 parameters.
CVE-2026-71310 1 Rclone 1 Rclone 2026-08-06 5.9 Medium
rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.0, the shared HTTP CONNECT helper in lib/proxy/http.go parses proxy CONNECT responses with http.ReadResponse over an unrestricted buffered reader, allowing a malicious or compromised configured proxy, or an active on-path actor controlling a plaintext HTTP proxy hop, to send oversized headers that grow memory until the rclone process fails. The affected helper is used by FTP and SFTP proxy connections, and SFTP reaches the parser before SSH server authentication, so target host key validation does not constrain a malicious proxy. This issue is fixed in 1.75.0.
CVE-2026-67856 1 Open62541 1 Open62541 2026-08-05 7.5 High
