### Impact The script API of the LESS compiler in XWiki is incorrectly checking for rights when calling the cache cleaning API, making it possible to clean the cache without having programming right. The only impact of this is a slowdown in XWiki execution as the caches are re-filled. As this vulnerability requires script right to exploit, and script right already allows unlimited execution of scripts, the additional impact due to this vulnerability is low. ### Patches This has been patched in XWiki 15.10.12, 16.4.3 and 16.8.0 RC1. ### Workarounds We're not aware of any workaround except for being careful whom to give script right, which is a general recommendation.

### Impact An open redirect vulnerability in the HTML conversion request filter allows attackers to construct URLs on an XWiki instance that redirect to any URL. To reproduce, open `<xwiki-host>/xwiki/bin/view/Main/?foo=bar&foo_syntax=invalid&RequiresHTMLConversion=foo&xerror=https://www.example.com/` where `<xwiki-host>` is the URL of your XWiki installation. ### Patches This bug has been fixed in XWiki 15.10.13, 16.4.4 and 16.8.0 by validating the domain of the redirect URL against the configured safe domains and the current request's domain. ### Workarounds A web application firewall could be configured to reject requests with the `xerror` parameter as from our analysis this parameter isn't used anymore. For requests with the `RequiresHTMLConversion` parameter set, the referrer URL should be checked if it points to the XWiki installation. Apart from that, we're not aware of any workarounds.

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).

In a new campaign detected in March 2025, senior members of the World Uyghur Congress (WUC) living in exile have been targeted by a Windows-based malware that's capable of conducting surveillance. The spear-phishing campaign involved the use of a trojanized version of a legitimate open-source word processing and spell check tool called UyghurEdit++ developed to support the use of the Uyghur

### Impact n8n workflows can store and serve binary files, which are accessible to authenticated users. However, there was no restriction on the MIME type of uploaded files, and the MIME type could be controlled via a GET parameter. This allowed the server to respond with any MIME type, potentially enabling malicious content to be interpreted and executed by the browser. An authenticated attacker with member-level permissions could exploit this by uploading a crafted HTML file containing malicious JavaScript. When another user visits the binary data endpoint with the MIME type set to text/html, the script executes in the context of the user’s session. This script could, for example, send a request to change the user’s email address in their account settings, effectively enabling account takeover. ### Patches - [[email protected]](https://github.com/n8n-io/n8n/releases/tag/n8n%401.90.0) ### Credit We would like to thank @Mahmoud0x00 for reporting this issue.

# Issue Snowflake discovered and remediated a vulnerability in the Snowflake Connector for .NET (“Connector”). When using the Easy Logging feature on Linux and macOS, the Connector didn’t correctly verify the permissions of the logging configuration file, potentially allowing an attacker with local access to overwrite the configuration and gain control over logging level and output location. This vulnerability affects Connector versions 2.1.2 through 4.4.0. Snowflake fixed the issue in version 4.4.1. # Vulnerability Details When using the Easy Logging feature on Linux and macOS, the Connector reads logging configuration from a user-provided file. On Linux and macOS, the Connector verifies that the configuration file can be written to only by its owner. That check was vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition and failed to verify that the file owner matches the user running the Connector. This could allow a local attacker with write access to the configurati...

### 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...
