go-git: Maliciously crafted idx file can cause asymmetric memory consumption

go-git is an extensible git implementation library written in pure Go. From version 5.0.0 to before version 5.17.1, a vulnerability has been identified in which a maliciously crafted .idx file can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a denial-of-service (DoS) condition. Exploitation requires write access to the local repository's .git directory, it order to create or alter existing .idx files. This issue has been patched in version 5.17.1.

A denial-of-service vulnerability exists in the NetX IPv6 component functionality of Eclipse ThreadX NetX Duo. A specially crafted network packet of "Packet Too Big" with more than 15 different source address can lead to denial of service. An attacker can send a malicious packet to trigger this vulnerability.

Stirling-PDF vulnerable to DoS via add-watermark

Stirling-PDF is a locally hosted web application that allows you to perform various operations on PDF files. Versions starting in 2.1.5 and prior to 2.5.2 have Denial of Service (DoS) vulnerability in the Stirling-PDF watermark functionality (`/api/v1/security/add-watermark` endpoint). The vulnerability allows authenticated users to cause resource exhaustion and server crashes by providing extreme values for the `fontSize` and `widthSpacer` parameters. Version 2.5.2 patches the issue.

Fleet's unbounded request body read allows remote Denial of Service

Fleet is open source device management software. Prior to 4.81.0, Fleet contained multiple unauthenticated HTTP endpoints that read request bodies without enforcing a size limit. An unauthenticated attacker could exploit this behavior by sending large or repeated HTTP payloads, causing excessive memory allocation and resulting in a denial-of-service (DoS) condition. Version 4.81.0 patches the issue.

Tornado has a DoS due to too many multipart parts

Tornado is a Python web framework and asynchronous networking library. In versions of Tornado prior to 6.5.5, the only limit on the number of parts in multipart/form-data is the max_body_size setting (default 100MB). Since parsing occurs synchronously on the main thread, this creates the possibility of denial-of-service due to the cost of parsing very large multipart bodies with many parts. This vulnerability is fixed in 6.5.5.

Incus vulnerable to denial of source through crafted bucket backup file

Incus is a system container and virtual machine manager. Prior to version 6.23.0, a specially crafted storage bucket backup can be used by an user with access to Incus' storage bucket feature to crash the Incus daemon. Repeated use of this attack can be used to keep the server offline causing a denial of service of the control plane API. This does not impact any running workload, existing containers and virtual machines will keep operating. Version 6.23.0 fixes the issue.

OpenClaw < 2026.3.13 - Resource Exhaustion via Unauthenticated Telegram Webhook Request

OpenClaw before 2026.3.13 reads and buffers Telegram webhook request bodies before validating the x-telegram-bot-api-secret-token header, allowing unauthenticated attackers to exhaust server resources. Attackers can send POST requests to the webhook endpoint to force memory consumption, socket time, and JSON parsing work before authentication validation occurs.

DoS attack via login attempts with multi-megabyte passwords

Mattermost versions 11.3.x <= 11.3.0, 11.2.x <= 11.2.2, 10.11.x <= 10.11.10 fail to properly handle very long passwords, which allows an attacker to overload the server CPU and memory via executing login attempts with multi-megabyte passwords. Mattermost Advisory ID: MMSA-2026-00587

Memory Allocation with Excessive Size Value in Wireshark

RTPS dissector memory leak in Wireshark 4.0.0 to 4.0.8 and 3.6.0 to 3.6.16 allows denial of service via packet injection or crafted capture file

Allocation of Resources Without Limits or Throttling in GitLab

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 13.7 before 18.8.7, 18.9 before 18.9.3, and 18.10 before 18.10.1 that could have allowed an authenticated user to cause a denial of service due to excessive resource consumption when handling certain CI-related inputs.

NATS is vulnerable to pre-auth DoS through WebSockets client service

NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, a malicious client which can connect to the WebSockets port can cause unbounded memory use in the nats-server before authentication; this requires sending a corresponding amount of data. This is a milder variant of CVE-2026-27571. That earlier issue was a compression bomb, this vulnerability is not. Attacks against this new issue thus require significant client bandwidth. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, disable websockets if not required for project deployment.
