### Impact When using Babel to compile [regular expression named capturing groups](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Named_capturing_group), Babel will generate a polyfill for the `.replace` method that has quadratic complexity on some specific replacement pattern strings (i.e. the second argument passed to `.replace`). Your generated code is vulnerable if _all_ the following conditions are true: - You use Babel to compile [regular expression named capturing groups](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Named_capturing_group) or - You use the `.replace` method on a regular expression that contains named capturing groups - **Your code uses untrusted strings as the second argument of `.replace`** If you are using `@babel/preset-env` with the [`targets`](https://babeljs.io/docs/options#targets) option, the transform that injects the vulnerable code is automatically enabled if: - you use...

### Summary A mock API configuration for static file serving following the same approach presented in the [documentation page](https://mockoon.com/tutorials/create-endpoint-serving-static-file/), where the server filename is generated via templating features from user input is vulnerable to Path Traversal and LFI, allowing an attacker to get any file in the mock server filesystem. The issue may be particularly relevant in cloud hosted server instances ### Details In `sendFileWithCallback`([code](https://github.com/mockoon/mockoon/blob/1ed31c4059d7f757f6cb2a43e10dc81b0d9c55a9/packages/commons-server/src/libs/server/server.ts#L1400)) and `sendFile`([code](https://github.com/mockoon/mockoon/blob/1ed31c4059d7f757f6cb2a43e10dc81b0d9c55a9/packages/commons-server/src/libs/server/server.ts#L1551)) the `filePath` variable is parsed using `TemplateParser` ```js let filePath = TemplateParser({ shouldOmitDataHelper: false, // replace backslashes with forward slashes, but not if f...

**Vulnerability type:** Prototype Pollution **Vulnerability Location(s):** ```js # v9.1 node_modules/@intlify/message-resolver/index.js # v9.2 or later node_modules/@intlify/vue-i18n-core/index.js ``` **Description:** The latest version of `@intlify/message-resolver (9.1)` and `@intlify/vue-i18n-core (9.2 or later)`, (previous versions might also affected), is vulnerable to Prototype Pollution through the entry function(s) `handleFlatJson`. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence. Moreover, the consequences of this vulnerability can escalate to other injection-based attacks, depending on how the library integrates within the application. For instance, if the polluted property propagates to sensitive Node.js APIs (e.g., exec, eval), it could enable an attacker to execute arbitrary commands within the application's context. **PoC:** ...

The MongoDB Shell may be susceptible to control character injection where an attacker with control over the database cluster contents can inject control characters into the shell output. This may result in the display of falsified messages that appear to originate from mongosh or the underlying operating system, potentially misleading users into executing unsafe actions. The vulnerability is exploitable only when mongosh is connected to a cluster that is partially or fully controlled by an attacker. This issue affects mongosh versions prior to 2.3.9.

The MongoDB Shell may be susceptible to control character injection where an attacker with control of the mongosh autocomplete feature, can use the autocompletion feature to input and run obfuscated malicious text. This requires user interaction in the form of the user using ‘tab’ to autocomplete text that is a prefix of the attacker’s prepared autocompletion. This issue affects mongosh versions prior to 2.3.9.  The vulnerability is exploitable only when mongosh is connected to a cluster that is partially or fully controlled by an attacker.

### Impact The matrix-appservice-irc bridge up to version 3.0.3 contains a vulnerability which can lead to arbitrary IRC command execution as the puppeted user. The attacker can only inject commands executed as their own IRC user. ### Patches The vulnerability has been patched in matrix-appservice-irc version 3.0.4. ### For more information If you have any questions or comments about this advisory, please email us at [security at matrix.org](mailto:security@matrix.org).

Inserts/JSX expressions inside illegal inlined JSX fragments lacked escaping, allowing user input to be rendered as HTML when put directly inside JSX fragments. For instance, `?text=<svg/onload=alert(1)>` would trigger XSS here. ```js const [text] = createResource(() => { return new URL(getRequestEvent().request.url).searchParams.get("text"); }); return ( <> Text: {text()} </> ); ```
