CVE-2021-43862 – Self XSS on user input

https://notcve.org/view.php?id=CVE-2021-43862

jQuery Terminal Emulator is a plugin for creating command line interpreters in your applications. Versions prior to 2.31.1 contain a low impact and limited cross-site scripting (XSS) vulnerability. The code for XSS payload is always visible, but an attacker can use other techniques to hide the code the victim sees. If the application uses the `execHash` option and executes code from URL, the attacker can use this URL to execute their code. The scope is limited because the javascript attribute used is added to span tag, so no automatic execution like with `onerror` on images is possible. • https://github.com/jcubic/jquery.terminal/commit/77eb044d0896e990d48a9157f0bc6648f81a84b5 https://github.com/jcubic/jquery.terminal/issues/727 https://github.com/jcubic/jquery.terminal/releases/tag/2.31.1 https://github.com/jcubic/jquery.terminal/security/advisories/GHSA-x9r5-jxvq-4387 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) •
