CWE-407
Allowed-with-ReviewInefficient Algorithmic Complexity
Abstraction: Class · Status: Incomplete
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
311 vulnerabilities reference this CWE, most recent first.
GHSA-Q8WF-6R8G-63CH
Vulnerability from github – Published: 2026-07-22 23:02 – Updated: 2026-07-22 23:02Impact
When self-hosting Next.js with the default image loader, the Image Optimization API can optimize remotely hosted images if configured (not enabled by default). If those images contain malicious content, they can cause CPU exhaustion in /_next/image endpoints.
- If you are using
config.images.remotePatterns, only the patterns in that array are impacted. - If you are using
config.images.unoptimized: true, you are NOT impacted. - If you are using
config.images.loader: 'custom', you are NOT impacted. - If you are using Vercel, you are NOT impacted.
Workarounds
If you cannot upgrade immediately, you can avoid the expensive work by setting config.experimental.imgOptSkipMetadata : true.

Advisory FAQ
How do I know if I am affected?
If you have a runtime or SDK with a version listed, or an affected package listed in affected software or affected packages, you're exposed to the vulnerability.
How do I fix the issue?
- To fix the issue please install the latest version of .NET 8.0 or .NET 6.0. If you have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET SDKs.
- .NET Framework-based applications and other application types need to perform a package update.
- If you have .NET 6.0 or greater installed, you can list the versions you have installed by running the
dotnet --infocommand. You will see output like the following;
.NET Core SDK (reflecting any global.json):

OS Name: Windows
OS Version: 10.0.18363
OS Platform: Windows
RID: win10-x64
Base Path: C:\Program Files\dotnet\sdk\6.0.300\
Host (useful for support):
Version: 8.0.3
Commit: 8473146e7d

Microsoft.AspNetCore.App 8.0.3 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.WindowsDesktop.App 8.0.3 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
To install additional .NET Core runtimes or SDKs:
https://aka.ms/dotnet-download
- If you're using .NET 9.0, you should download and install .NET 9.0 RC 2 Runtime or .NET 9.0.100-rc.2.24474.11 SDK (for Visual Studio 2022 v17.12 latest Preview) from https://dotnet.microsoft.com/download/dotnet-core/9.0.
- If you're using .NET 8.0, you should download and install .NET 8.0.10 Runtime or .NET 8.0.110 SDK (for Visual Studio 2022 v17.8) from https://dotnet.microsoft.com/download/dotnet-core/8.0.
- If you're using .NET 6.0, you should download and install .NET 6.0.35 Runtime or .NET 6.0.135 SDK (for Visual Studio 2022 v17.6) from https://dotnet.microsoft.com/download/dotnet-core/6.0.
.NET 6.0 and .NET 8.0 updates are also available from Microsoft Update. To access this either type "Check for updates" in your Windows search, or open Settings, choose Update & Security and then click Check for Updates.
Once you have installed the updated runtime or SDK, restart your apps for the update to take effect.
Additionally, if you've deployed self-contained applications targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.

Vulnerability from github – Published: 2026-03-18 16:17 – Updated: 2026-03-20 21:27Impact
An attacker who uses this vulnerability can craft a PDF which leads to long runtimes and/or large memory usage. This requires accessing an array-based stream with lots of entries.
Patches
This has been fixed in pypdf==6.9.1.
Workarounds
If you cannot upgrade yet, consider applying the changes from PR #3686.

GHSA-QW25-V68C-QJF3
Vulnerability from github – Published: 2025-11-05 15:31 – Updated: 2026-06-05 14:33An issue was discovered in 5.1 before 5.1.14, 4.2 before 4.2.26, and 5.2 before 5.2.8.
NFKC normalization in Python is slow on Windows. As a consequence, django.http.HttpResponseRedirect, django.http.HttpResponsePermanentRedirect, and the shortcut django.shortcuts.redirect were subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Seokchan Yoon for reporting this issue.

Vulnerability from github – Published: 2024-11-18 18:30 – Updated: 2024-11-18 18:30A vulnerability in the Transport Layer Security (TLS) protocol implementation of Cisco AsyncOS software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause high CPU usage on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to inefficient processing of incoming TLS traffic. An attacker could exploit this vulnerability by sending a series of crafted TLS packets to an affected device. A successful exploit could allow the attacker to trigger a prolonged state of high CPU utilization. The affected device would still be operative, but response time and overall performance may be degraded.There are no workarounds that address this vulnerability.
