CVE-2026-86202 2026-09-09 N/A 4.3 MEDIUM
PocketMine-MP versions before 5.39.2 contain a network amplification vulnerability in ActorEventPacket handling that allows clients to trigger consuming animations for all visible players. Attackers can send crafted ActorEventPacket messages to spam animation events to other clients and waste server CPU and memory resources.
CVE-2026-68080 1 Apache 1 Qpid Broker-j 2026-08-06 N/A 6.5 MEDIUM
It was not possible to govern the rate at which the broker would respond to an echo flow, enabling an authenticated attacker to cause excessive resource usage and potential denial of service. This issue affects Apache Qpid Broker-J: through 10.0.1. Users are recommended to upgrade to version 10.1.0, which fixes the issue.
CVE-2026-54609 2026-07-30 N/A 8.6 HIGH
QTI Neon is a minimal, game-agnostic, relay-based UDP multiplayer protocol library. In version 1.0.0, the relay's handleReconnectRequest forwards RECONNECT_REQUEST packets to the host without bounding them, so an unauthenticated client can drive relay-to-host amplification and cause a denial of service on the host. No fixed version is available as of this review.
CVE-2026-50045 1 Nlnetlabs 1 Unbound 2026-07-24 N/A 5.3 MEDIUM
In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, a single client query for a deeply nested name under a DNSSEC-signed parent can cause Unbound to send more upstream packets per client query than the configured 'max-global-quota'. This effectively bypasses a security configuration that limits upstream amplification traffic.
CVE-2026-45557 2026-07-24 N/A 5.8 MEDIUM
Technitium DNS Server aggressively tries to fetch missing RRSIG records or mismatched DNSKEY records. An attacker in control of a domain can cause a vulnerable system to generate excessive network traffic. Fixed in 15.0.
CVE-2025-58066 2026-06-17 N/A 5.3 MEDIUM
nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. In versions between 1.2.0 and 1.6.1 inclusive servers which allow non-NTS traffic are affected by a denial of service vulnerability, where an attacker can induce a message storm between two NTP servers running ntpd-rs. Client-only configurations are not affected. Affected users are recommended to upgrade to version 1.6.2 as soon as possible.
CVE-2024-25015 3 Ibm, Linux, Microsoft 5 Aix, Linux On Ibm Z, Mq and 2 more 2026-06-17 N/A 7.5 HIGH
IBM MQ 9.2 LTS, 9.3 LTS, and 9.3 CD Internet Pass-Thru could allow a remote user to cause a denial of service by sending HTTP requests that would consume all available resources. IBM X-Force ID: 281278.
CVE-2023-49203 1 Technitium 1 Dnsserver 2026-06-17 N/A 7.5 HIGH
Technitium 11.5.3 allows remote attackers to cause a denial of service (bandwidth amplification) because the DNSBomb manipulation causes accumulation of low-rate DNS queries such that there is a large-sized response in a burst of traffic.
CVE-2023-28456 1 Technitium 1 Dnsserver 2026-06-17 N/A 7.5 HIGH
An issue was discovered in Technitium through 11.0.2. It enables attackers to launch amplification attacks (3 times more than other "golden model" software like BIND) and cause potential DoS.
CVE-2023-28455 1 Technitium 1 Dnsserver 2026-06-17 N/A 7.5 HIGH
An issue was discovered in Technitium through 11.0.2. The forwarding mode enables attackers to create a query loop using Technitium resolvers, launching amplification attacks and causing potential DoS.
CVE-2022-0028 1 Paloaltonetworks 1 Pan-os 2026-06-17 N/A 8.6 HIGH
A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo Alto Networks PA-Series (hardware), VM-Series (virtual) and CN-Series (container) firewall against an attacker-specified target. To be misused by an external attacker, the firewall configuration must have a URL filtering profile with one or more blocked categories assigned to a source zone that has an external facing interface. This configuration is not typical for URL filtering and, if set, is likely unintended by the administrator. If exploited, this issue would not impact the confidentiality, integrity, or availability of our products. However, the resulting denial-of-service (DoS) attack may help obfuscate the identity of the attacker and implicate the firewall as the source of the attack. We have taken prompt action to address this issue in our PAN-OS software. All software updates for this issue are expected to be released no later than the week of August 15, 2022. This issue does not impact Panorama M-Series or Panorama virtual appliances. This issue has been resolved for all Cloud NGFW and Prisma Access customers and no additional action is required from them.
CVE-2021-4234 1 Openvpn 1 Openvpn Access Server 2026-06-17 5.0 MEDIUM 7.5 HIGH
OpenVPN Access Server 2.10 and prior versions are susceptible to resending multiple packets in a response to a reset packet sent from the client which the client again does not respond to, resulting in a limited amplification attack.
CVE-2021-43547 1 Twinoakscomputing 1 Coredx Dds 2026-06-17 8.5 HIGH 7.5 HIGH
TwinOaks Computing CoreDX DDS versions prior to 5.9.1 are susceptible to exploitation when an attacker sends a specially crafted packet to flood target devices with unwanted traffic. This may result in a denial-of-service condition and information exposure.
CVE-2021-38487 1 Rti 3 Connext Dds Micro, Connext Professional, Connext Secure 2026-06-17 6.4 MEDIUM 8.2 HIGH
RTI Connext Professional versions 4.1 to 6.1.0, and Connext Micro versions 2.4 and later are vulnerable when an attacker sends a specially crafted packet to flood target devices with unwanted traffic. This may result in a denial-of-service condition and information exposure.
CVE-2021-38429 1 Objectcomputing 1 Opendds 2026-06-17 6.4 MEDIUM 6.6 MEDIUM
OCI OpenDDS versions prior to 3.18.1 are vulnerable when an attacker sends a specially crafted packet to flood target devices with unwanted traffic, which may result in a denial-of-service condition and information exposure.
CVE-2021-38425 1 Eprosima 1 Fast Dds 2026-06-17 6.4 MEDIUM 7.5 HIGH
eProsima Fast DDS versions prior to 2.4.0 (#2269) are susceptible to exploitation when an attacker sends a specially crafted packet to flood a target device with unwanted traffic, which may result in a denial-of-service condition and information exposure.
CVE-2021-38135 1 Microfocus 1 Imanager 2026-06-17 N/A 8.6 HIGH
Possible External Service Interaction attack in iManager has been discovered in OpenTextâ„¢ iManager 3.2.6.0000.
CVE-2020-10772 2 Nlnetlabs, Redhat 2 Unbound, Enterprise Linux 2026-06-17 5.0 MEDIUM 7.5 HIGH
An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions of Unbound could still amplify an incoming query into a large number of queries directed to a target, even with a lower amplification ratio compared to versions of Unbound that shipped before the mentioned erratum. This issue is about the incomplete fix for CVE-2020-12662, and it does not affect upstream versions of Unbound.
CVE-2019-14850 2 Nbdkit Project, Redhat 4 Nbdkit, Enterprise Linux, Enterprise Linux Server and 1 more 2026-06-17 2.6 LOW 3.7 LOW
A denial of service vulnerability was discovered in nbdkit 1.12.7, 1.14.1 and 1.15.1. An attacker could connect to the nbdkit service and cause it to perform a large amount of work in initializing backend plugins, by simply opening a connection to the service. This vulnerability could cause resource consumption and degradation of service in nbdkit, depending on the plugins configured on the server-side.
