### Impact This impacts users that use shescape to escape arguments: - for the Unix shell Bash, or any not-officially-supported Unix shell; - using the `escape` or `escapeAll` functions with the `interpolation` option set to `true`. An attacker can cause polynomial backtracking in terms of the input string length due to a Regular Expression in shescape that is vulnerable to Regular Expression Denial of Service (ReDoS). Example: ```javascript import * as shescape from "shescape"; /* 1. Prerequisites */ const options = { interpolation: true, // and shell: "/bin/bash", // or shell: "some-not-officially-supported-shell", // or shell: undefined, // Only if the system's default shell is bash or an unsupported shell. }; /* 2. Attack */ let userInput = '{,'.repeat(150_000); // polynomial backtracking /* 3. Usage */ shescape.escape(userInput, options); // or shescape.escapeAll([userInput], options); ``` ### Patches This bug has been patched in [v1.6.1](https://github.com/...
### Description Due to the common practice of providing vulnerability details in markdown format, the Dependency-Track frontend renders them using the JavaScript library [Showdown](https://github.com/showdownjs/showdown). Showdown [does not have any XSS countermeasures built in](https://github.com/showdownjs/showdown/wiki/Markdown's-XSS-Vulnerability-(and-how-to-mitigate-it)), and versions before 4.6.1 of the Dependency-Track frontend did not encode or sanitize Showdown's output. This made it possible for arbitrary JavaScript included in vulnerability details via HTML attributes to be executed in context of the frontend. ### Impact Actors with the `VULNERABILITY_MANAGEMENT` permission can exploit this weakness by creating or editing a custom vulnerability and providing XSS payloads in any of the following fields: * Description * Details * Recommendation * References The payload will be executed for users with the `VIEW_PORTFOLIO` permission when browsing to the modified vulnerabil...
A pair of Microsoft bugs allow cyberattackers to bypass native Windows Internet download security, says former CERT CC researcher who discovered the flaws.
A vulnerability in Batik of Apache XML Graphics allows an attacker to run untrusted Java code from an SVG. This issue affects Apache XML Graphics prior to 1.16. It is recommended to update to version 1.16.
A vulnerability in Batik of Apache XML Graphics allows an attacker to run Java code from untrusted SVG via JavaScript. This issue affects Apache XML Graphics prior to 1.16. Users are recommended to upgrade to version 1.16.
PRTG Network Monitor through 22.2.77.2204 does not prevent custom input for a device’s icon, which can be modified to insert arbitrary content into the style tag for that device. When the device page loads, the arbitrary Cascading Style Sheets (CSS) data is inserted into the style tag, loading malicious content. Due to PRTG Network Monitor preventing “characters, and from modern browsers disabling JavaScript support in style tags, this vulnerability could not be escalated into a Cross-Site Scripting vulnerability.

There is a reflected cross site scripting issue in the Esri ArcGIS Server services directory versions 10.9.1 and below that may allow a remote, unauthenticated attacker to convince a user to click on a crafted link which could potentially execute arbitrary JavaScript code in the victim’s browser.
