Cross-site Scripting (XSS) in aimhubio Aim 3.28.0 allows remote attackers to execute arbitrary JavaScript in victims browsers via malicious Python code submitted to the /api/reports endpoint, which is interpreted and executed by Pyodide when the report is viewed. No sanitisation or sandbox restrictions prevent JavaScript execution via pyodide.code.run_js().

### Summary form-data uses `Math.random()` to select a boundary value for multipart form-encoded data. This can lead to a security issue if an attacker: 1. can observe other values produced by Math.random in the target application, and 2. can control one field of a request made using form-data Because the values of Math.random() are pseudo-random and predictable (see: https://blog.securityevaluators.com/hacking-the-javascript-lottery-80cc437e3b7f), an attacker who can observe a few sequential values can determine the state of the PRNG and predict future values, includes those used to generate form-data's boundary value. The allows the attacker to craft a value that contains a boundary value, allowing them to inject additional parameters into the request. This is largely the same vulnerability as was [recently found in `undici`](https://hackerone.com/reports/2913312) by [`parrot409`](https://hackerone.com/parrot409?type=user) -- I'm not affiliated with that researcher but want to giv...

Fake npm website used in phishing attack to steal maintainer token, leading to malware in popular JavaScript packages like eslint-config-prettier.

### Summary The `version` parameter of the `/docs` endpoint is vulnerable to a Reflected XSS (Cross-Site Scripting) attack. ### PoC 1. Setup a minimal app following the quickstart guide: https://docs.cadwyn.dev/quickstart/setup/ 2. Click on the following PoC link: http://localhost:8000/docs?version=%27%2balert(document.domain)%2b%27 ### Impact Refer to this [security advisory](https://github.com/Visionatrix/Visionatrix/security/advisories/GHSA-w36r-9jvx-q48v) for an example of the impact of a similar vulnerability that shares the same root cause. This XSS would notably allow an attacker to execute JavaScript code on a user's session for any application based on `Cadwyn` via a one-click attack. A CVSS for the average case may be: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:L ### Details The vulnerable code snippet can be found in the 2 functions `swagger_dashboard` and `redoc_dashboard`: https://github.com/zmievsa/cadwyn/blob/main/cadwyn/applications.py#L387-L413 The implementation...

A 72-hour sprint that produced working solutions for one of game development's hardest problems: making it accessible to non-programmers.

A new attack campaign has compromised more than 3,500 websites worldwide with JavaScript cryptocurrency miners, marking the return of browser-based cryptojacking attacks once popularized by the likes of CoinHive.  Although the service has since shuttered after browser makers took steps to ban miner-related apps and add-ons, researchers from the c/side said they found evidence of a stealthy

### Summary A **remote script-inclusion / stored XSS** vulnerability in **@nuxtjs/mdc** lets a Markdown author inject a `<base href="https://attacker.tld">` element. The `<base>` tag rewrites how all subsequent relative URLs are resolved, so an attacker can make the page load scripts, styles, or images from an external, attacker-controlled origin and execute arbitrary JavaScript in the site’s context. ### Details - **Affected file** : `src/runtime/parser/utils/props.ts` - **Core logic**  : `validateProp()` inspects * attributes that start with `on` → blocked * `href` or `src` → filtered by `isAnchorLinkAllowed()` Every other attribute and every **tag** (including `<base>`) is allowed unchanged, so the malicious `href` on `<base>` is never validated. ``` export const validateProp = (attribute: string, value: string) => { if (attribute.startsWith('on')) return false if (attribute === 'href' || attribute === 'src') { return isAnchorLinkAllowed(value) } retur...

### Summary The `ConfigCommentParser#parseJSONLikeConfig` API is vulnerable to a Regular Expression Denial of Service (ReDoS) attack in its only argument. ### Details The regular expression at [packages/plugin-kit/src/config-comment-parser.js:158](https://github.com/eslint/rewrite/blob/bd4bf23c59f0e4886df671cdebd5abaeb1e0d916/packages/plugin-kit/src/config-comment-parser.js#L158) is vulnerable to a quadratic runtime attack because the grouped expression is not anchored. This can be solved by prepending the regular expression with `[^-a-zA-Z0-9/]`. ### PoC ```javascript const { ConfigCommentParser } = require("@eslint/plugin-kit"); const str = `${"A".repeat(1000000)}?: 1 B: 2`; console.log("start") var parser = new ConfigCommentParser(); console.log(parser.parseJSONLikeConfig(str)); console.log("end") // run `npm i @eslint/plugin-kit@0.3.3` and `node attack.js` // then the program will stuck forever with high CPU usage ``` ### Impact This is a Regular Expression Denial of Serv...

A vulnerability, which was classified as critical, was found in Xuxueli xxl-job up to 3.1.1. Affected is the function httpJobHandler of the file src\main\java\com\xxl\job\executor\service\jobhandler\SampleXxlJob.java. The manipulation leads to server-side request forgery. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

Hackers are exploiting a new TeleMessage SGNL flaw that exposes sensitive data. CISA warns agencies to patch or stop using it by July 22.
