The latest Secure by Design alert from CISA outlines recommended actions security teams should implement to reduce the prevalence of cross-site scripting vulnerabilities in software.

A researcher bypassed the Calendar sandbox, Gatekeeper, and TCC in a chain attack that allowed for wanton theft of iCloud photos.

### Summary We discovered a DOM Clobbering vulnerability in Vite when building scripts to `cjs`/`iife`/`umd` output format. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. Note that, we have identified similar security issues in Webpack: https://github.com/webpack/webpack/security/advisories/GHSA-4vvj-4cpr-p986 ### Details **Backgrounds** DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering, here are some references: [1] https://scnps.co/papers/sp23_domclob.pdf [2] https://research.securitum.com/xss-in-amp4email-dom-clobbering/ **Gadg...

A vulnerability was found in the ilab model serve component, where improper handling of the best_of parameter in the vllm JSON web API can lead to a Denial of Service (DoS). The API used for LLM-based sentence or chat completion accepts a best_of parameter to return the best completion from several options. When this parameter is set to a large value, the API does not handle timeouts or resource exhaustion properly, allowing an attacker to cause a DoS by consuming excessive system resources. This leads to the API becoming unresponsive, preventing legitimate users from accessing the service.

### Summary A potential Cross-Site Scripting (XSS) vulnerability has been identified in the `/wireui/button` endpoint, specifically through the `label` query parameter. Malicious actors could exploit this vulnerability by injecting JavaScript into the `label` parameter, leading to the execution of arbitrary code in the victim's browser. ### Details The `/wireui/button` endpoint dynamically renders button labels based on user-provided input via the `label` query parameter. Due to insufficient sanitization or escaping of this input, an attacker can inject malicious JavaScript. The following URL demonstrates the vulnerability: ``` https://wireui.dev/wireui/button?label=Cancel&1%25%7ds8dk0%3E%3Cscript%3Ealert(1)%3C/script%3Ez1qt3=1 ``` By crafting such a request, an attacker can inject arbitrary code that will be executed by the browser when the endpoint is accessed. ### Proof of Concept (PoC) To demonstrate the vulnerability, visit the following URL: ``` /wireui/button?label=<script>...

### Impact An authenticated user can mute alert rules from arbitrary organizations and projects given a known given rule ID. The user does not need to be a member of the organization or have permissions on the project. In our review, we have identified no instances where alerts have been muted by unauthorized parties. ### Patches A patch was issued to ensure authorization checks are properly scoped on requests to mute alert rules. Authenticated users who do not have the necessary permissions are no longer able to mute alerts. Sentry SaaS users do not need to take any action. [Self-Hosted Sentry](https://github.com/getsentry/self-hosted) users should upgrade to version **24.9.0** or higher. ### Affected Versions The rule mute feature was generally available as of 23.6.0 but users with early access may have had the feature as of 23.4.0. ### References - [Prevent muting alerts](https://github.com/getsentry/sentry/pull/77016)

### Impact An authenticated user may delete user issue alert notifications for arbitrary users given a known alert ID. ### Patches A patch was issued to ensure authorization checks are properly scoped on requests to delete user alert notifications. Sentry SaaS users do not need to take any action. [Self-Hosted Sentry](https://github.com/getsentry/self-hosted) users should upgrade to version **24.9.0** or higher. ### References - [Prevent muting user alerts](https://github.com/getsentry/sentry/pull/77093/)

Ubuntu Security Notice 7001-2 - USN-7001-1 fixed vulnerabilities in xmltol library. This update provides the corresponding updates for Ubuntu 24.04 LTS. Shang-Hung Wan discovered that Expat, contained within the xmltok library, did not properly handle certain function calls when a negative input length was provided. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code.

The czim/file-handling package before 1.5.0 and 2.x before 2.3.0 (used with PHP Composer) does not properly validate URLs within makeFromUrl and makeFromAny, leading to SSRF, and to directory traversal for the reading of local files.

It is imperative to develop robust policies for new tech and future-proofing by favoring investments in security.
