This vulnerability allows an attacker to inject malicious JavaScript code into a user\u0026rsquo;s browser by convincing them to click on a specially crafted URL. When the victim visits the malicious URL, the injected script executes within their browser session, potentially enabling the attacker to steal cookies, redirect the user to a malicious website, or deface the web page. This vulnerability poses a significant risk to Adobe Connect users, as it can lead to account compromise and data breaches. Exploitation requires user interaction, but the impact can be severe.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker crafts a malicious URL containing a JavaScript payload within a parameter.\u003c/li\u003e\n\u003cli\u003eThe attacker distributes the crafted URL via email, social media, or other means to a targeted user.\u003c/li\u003e\n\u003cli\u003eThe victim clicks on the malicious link, unknowingly initiating the XSS attack.\u003c/li\u003e\n\u003cli\u003eThe user\u0026rsquo;s browser sends a request to the Adobe Connect server with the malicious JavaScript in the URL.\u003c/li\u003e\n\u003cli\u003eThe Adobe Connect server reflects the malicious JavaScript code back to the user\u0026rsquo;s browser without proper sanitization.\u003c/li\u003e\n\u003cli\u003eThe victim\u0026rsquo;s browser executes the reflected JavaScript code within the context of the Adobe Connect application.\u003c/li\u003e\n\u003cli\u003eThe attacker can then steal the victim\u0026rsquo;s session cookies.\u003c/li\u003e\n\u003cli\u003eUsing the stolen cookies, the attacker can hijack the victim\u0026rsquo;s session, gaining unauthorized access to their Adobe Connect account and data.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this reflected XSS vulnerability (CVE-2026-27245) in Adobe Connect could lead to unauthorized access to user accounts, sensitive data, and the Adobe Connect environment.
