### Summary A Regular Expression Denial of Service (ReDoS) vulnerability exists in the processing of HTTP request headers. By sending an authorization header containing an excessively long sequence of spaces followed by a newline and "@", an attacker can exploit inefficient regular expression processing, leading to excessive resource consumption. This can significantly degrade server performance or cause a denial-of-service (DoS) condition, impacting availability. ### Details The issue occurs at [line 52](https://github.com/octokit/request-error.js/blob/main/src/index.ts) of iterator.ts in the @octokit/request-error repository. The vulnerability is caused by the use of an inefficient regular expression in the handling of the `authorization` header within the request processing logic: ```js authorization: options.request.headers.authorization.replace( / .*$/, " [REDACTED]" ) ``` The regular expression `/ .*$/` matches a space followed by any number of characters until the end of th...

### Summary The `vlSelectionTuples` function can be used to call JavaScript functions, leading to XSS. ### Details [`vlSelectionTuples`](https://github.com/vega/vega/blob/b45cf431cd6c0d0c0e1567f087f9b3b55bc236fa/packages/vega-selections/src/selectionTuples.js#L14) calls multiple functions that can be controlled by an attacker, including one call with an attacker-controlled argument. Example call: `vlSelectionTuples([{datum:<argument>}], {fields:[{getter:<function>}]})` This can be used to call `Function()` with arbitrary JavaScript and the resulting function can be called with `vlSelectionTuples` or using a type coercion to call `toString` or `valueOf`. ### PoC ``` {"$schema":"https://vega.github.io/schema/vega/v5.json","signals":[{"name":"a","init":"+{valueOf:vlSelectionTuples([{datum:'alert(1)'}],{fields:[{getter:[].at.constructor}]})[0].values[0]}"}]} ```

## Description Label Studio's `/projects/upload-example` endpoint allows injection of arbitrary HTML through a `GET` request with an appropriately crafted `label_config` query parameter. By crafting a specially formatted XML label config with inline task data containing malicious HTML/JavaScript, an attacker can achieve Cross-Site Scripting (XSS). While the application has a Content Security Policy (CSP), it is only set in report-only mode, making it ineffective at preventing script execution. The vulnerability exists because the upload-example endpoint renders user-provided HTML content without proper sanitization on a GET request. This allows attackers to inject and execute arbitrary JavaScript in victims' browsers by getting them to visit a maliciously crafted URL. This is considered vulnerable because it enables attackers to execute JavaScript in victims' contexts, potentially allowing theft of sensitive data, session hijacking, or other malicious actions. ## Steps to reproduce ...

**Summary / Details** Systems running the Instaclustr fork of Stratio's Cassandra-Lucene-Index plugin versions 4.0-rc1-1.0.0 through 4.0.16-1.0.0 and 4.1.0-1.0.0 through 4.1.8-1.0.0, installed into Apache Cassandra version 4.x, are susceptible to a vulnerability which when successfully exploited could allow authenticated Cassandra users to remotely bypass RBAC to access data and and escalate their privileges. **Affected Versions** - Cassandra-Lucene-Index plugin versions 4.0-rc1-1.0.0 through 4.0.16-1.0.0 - versions 4.1.0-1.0.0 through 4.1.8-1.0.0 when installed into Apache Cassandra version 4.x. **Required Configuration for Exploit** These are the conditions required to enable exploit: 1. Cassandra 4.x 2. Vulnerable version of the Cassandra-Lucene-Index plugin configured for use 3. Data added to tables 4. Lucene index created 5. Cassandra flush has run **Mitigation/Prevention** Mitigation requires dropping all Lucene indexes and stopping use of the plugin. Exploit will be possibl...

### Summary This report finds 2 availability issues due to the regex used in the `parse-duration` npm package: 1. An event loop delay due to the CPU-bound operation of resolving the provided string, from a 0.5ms and up to ~50ms per one operation, with a varying size from 0.01 MB and up to 4.3 MB respectively. 2. An out of memory that would crash a running Node.js application due to a string size of roughly 10 MB that utilizes unicode characters. ### PoC Refer to the following proof of concept code that provides a test case and makes use of the regular expression in the library as its test case to match against strings: ```js // Vulnerable regex to use from the library: import parse from './index.js' function generateStressTestString(length, decimalProbability) { let result = ""; for (let i = 0; i < length; i++) { if (Math.random() < decimalProbability) { result += "....".repeat(99); } result += Math.floor(Math.random() * 10); } return result; } function ...
