CVE-2026-45646

A flaw was found in ASP.NET Core. This vulnerability allows an unauthorized remote attacker to cause a Denial of Service DoS by allocating resources without limits or throttling. This can lead to the affected system becoming unresponsive or unavailable to legitimate users...

CVE-2026-50506

A flaw was found in ASP.NET Core where an unauthorized remote attacker can cause a Denial of Service DoS over a network. This vulnerability occurs due to the allocation of resources without proper limits or throttling mechanisms, allowing an attacker to exhaust available resources and disrupt...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the buildchaininner function. An attacker can cause excessive resource consumption by submitting a certificate chain containing duplicate self-signed intermediates, which lead...

Important: unbound

Issue Overview: In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, insufficient validation of the RRSIG.Labels field combined with premature cache writes during RFC 8198 aggressive NSEC processing leads to cache poisoning that permits a malicious actor controlling a single delegated zone to...

Important: dotnet10.0

Issue Overview: Incorrect implementation of authentication algorithm in ASP.NET Core allows an authorized attacker to elevate privileges over a network. CVE-2026-47300 Allocation of resources without limits or throttling in .NET allows an unauthorized attacker to deny service over a network...

Amazon Linux 2023 : aspnetcore-runtime-8.0, aspnetcore-runtime-dbg-8.0, aspnetcore-targeting-pack-8.0 (ALAS2023-2026-2010)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2010 advisory. Incorrect implementation of authentication algorithm in ASP.NET Core allows an authorized attacker to elevate privileges over a network. CVE-2026-47300 Allocation of resources without limits o...

thrift: Apache Thrift Python bindings: Denial of Service via data amplification

A flaw was found in Apache Thrift Python bindings. This vulnerability involves the improper handling of highly compressed data, leading to a data amplification issue. An attacker could exploit this by providing specially crafted compressed input, which may cause the application to consume excessi...

thrift: Apache Thrift: Denial of Service due to uncontrolled resource allocation

A flaw was found in Apache Thrift Java bindings. This vulnerability, categorized as an Allocation of Resources Without Limits or Throttling, allows a remote attacker to cause a denial of service by exhausting system resources. The flaw occurs when the application fails to properly limit or thrott...

thrift: Apache Thrift Node.js bindings: Denial of Service due to inefficient algorithmic complexity and resource allocation

A flaw was found in Apache Thrift Node.js bindings. This vulnerability, stemming from inefficient algorithmic complexity and the allocation of resources without proper limits or throttling, allows a remote attacker to cause a Denial of Service DoS. By exploiting this, an attacker can consume...
