### Impact In a multi-node vLLM deployment, vLLM uses ZeroMQ for some multi-node communication purposes. The primary vLLM host opens an `XPUB` ZeroMQ socket and binds it to ALL interfaces. While the socket is always opened for a multi-node deployment, it is only used when doing tensor parallelism across multiple hosts. Any client with network access to this host can connect to this `XPUB` socket unless its port is blocked by a firewall. Once connected, these arbitrary clients will receive all of the same data broadcasted to all of the secondary vLLM hosts. This data is internal vLLM state information that is not useful to an attacker. By potentially connecting to this socket many times and not reading data published to them, an attacker can also cause a denial of service by slowing down or potentially blocking the publisher. ### Detailed Analysis The `XPUB` socket in question is created here: https://github.com/vllm-project/vllm/blob/c21b99b91241409c2fdf9f3f8c542e8748b317be/vllm/d...
### Summary The request to commence a site backup can be performed without authentication. Then these backups can also be downloaded without authentication. The archives are created with a predictable filename, so a malicious user could create an archive and then download the archive without being authenticated. ### Details Create an installation using the instructions found in the docker folder of the repository, setup the site, and then send the request to create an archive, which you do not need to be authenticated for: ``` POST /?api/archives HTTP/1.1 Host: localhost:8085 action=startArchive¶ms%5Bsavefiles%5D=true¶ms%5Bsavedatabase%5D=true&callAsync=true ``` Then to retrieve it, make a simple `GET` request like to the correct URL: ``` http://localhost:8085/?api/archives/2025-04-12T14-34-01_archive.zip ``` A malicious attacker could simply fuzz this filename. ### PoC Here is a python script to fuzz this: ``` #!/usr/bin/env python3 import requests import argpars...
A Regular Expression Denial of Service (ReDoS) vulnerability was identified in the huggingface/transformers library, specifically in the file `tokenization_gpt_neox_japanese.py` of the GPT-NeoX-Japanese model. The vulnerability occurs in the SubWordJapaneseTokenizer class, where regular expressions process specially crafted inputs. The issue stems from a regex exhibiting exponential complexity under certain conditions, leading to excessive backtracking. This can result in high CPU usage and potential application downtime, effectively creating a Denial of Service (DoS) scenario. The affected version is v4.48.1 (latest).

Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service. This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5. Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue.
### Summary There is a possibility for denial of service by memory exhaustion when `net-imap` reads server responses. At any time while the client is connected, a malicious server can send can send a "literal" byte count, which is automatically read by the client's receiver thread. The response reader immediately allocates memory for the number of bytes indicated by the server response. This should not be an issue when securely connecting to trusted IMAP servers that are well-behaved. It can affect insecure connections and buggy, untrusted, or compromised servers (for example, connecting to a user supplied hostname). ### Details The IMAP protocol allows "literal" strings to be sent in responses, prefixed with their size in curly braces (e.g. `{1234567890}\r\n`). When `Net::IMAP` receives a response containing a literal string, it calls `IO#read` with that size. When called with a size, `IO#read` immediately allocates memory to buffer the entire string before processing continu...

Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to properly validate the props used by the RetrospectivePost custom post type in the Playbooks plugin, which allows an attacker to create a specially crafted post with maliciously crafted props and cause a denial of service (DoS) of the web app for all users.
Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to validate the uniqueness and quantity of task actions within the UpdateRunTaskActions GraphQL operation, which allows an attacker to create task items containing an excessive number of actions triggered by specific posts, overloading the server and leading to a denial-of-service (DoS) condition.
