CVE-2019-8331 is a cross-site scripting vulnerability in Bootstrap versions before 3.4.1 and Bootstrap 4.3.x before 4.3.1. Bootstrap tooltip and popover components insufficiently sanitize content supplied through the data-template attribute. An attacker who can control data passed to those components can inject HTML or JavaScript that is rendered and executed when a tooltip or popover event fires.

Repository contains a single Python proof-of-concept exploit, CVE-2026-36214.py, plus documentation and license files. The exploit targets a stored XSS condition in osTicket caused by use of vulnerable Bootstrap Tooltip 3.3.4 behavior via the data-template attribute. The script is not a full automation framework; instead it is an operator aid that can: (1) check likely osTicket paths on a target, (2) generate a JavaScript payload file for upload as an attachment, (3) generate malicious HTML to paste into a ticket body referencing the uploaded same-origin script URL, (4) generate a fallback iframe/data-URI payload that redirects the victim if JS uploads are blocked, and (5) print an 'auto' workflow that combines these steps but still requires manual upload/paste actions. Network interaction in code is limited to GET requests against target-relative paths /scp/, /tickets.php, and /index.php for reconnaissance. The actual exploit delivery is browser/web-based: an attacker submits a crafted ticket so that when an agent or administrator views it, attacker-controlled JavaScript executes in their authenticated session. Documentation explains that same-origin attachment URLs such as file.php?key=... are important because CSP may block third-party script sources, while uploaded JS served by the application can still execute. Overall, this is a real operational PoC for stored XSS/session compromise in osTicket, with basic payload generation rather than a weaponized end-to-end exploit.
This repository is a collection of proof-of-concept (PoC) exploits for historical XSS vulnerabilities in the Bootstrap front-end framework. The main file, 'test.html', is a standalone HTML page that demonstrates four different XSS vulnerabilities (CVE-2019-8331, CVE-2018-14040, CVE-2016-10735, CVE-2024-6485) affecting various versions of Bootstrap 3.x and 4.x. Each PoC is clearly labeled and includes instructions for selecting the appropriate library version by editing the <head> section of the HTML file. The XSS payloads are injected via vulnerable HTML attributes and trigger JavaScript alert popups when the user interacts with the page elements. The repository is intended for educational and research purposes, providing a safe, local environment to study these vulnerabilities without requiring a backend server. The structure is simple, with the main exploit logic contained in 'test.html', a configuration example in 'evil.yml', and documentation in 'README.md'.
