12.10.1
CVE-2026-27243 describes a reflected Cross-Site Scripting (XSS) vulnerability present in Adobe Connect versions 2025.3 and earlier, including 12.10. Successful exploitation allows an attacker to inject malicious scripts into a web page viewed by a victim. This can lead to account compromise or session hijacking. The vulnerability is resolved in Adobe Connect version 2025.3.
This XSS vulnerability allows an attacker to execute arbitrary JavaScript code within the context of a victim's browser session on an Adobe Connect server. The attacker could leverage this to steal session cookies, redirect users to malicious websites, or deface the Adobe Connect interface. The impact is particularly severe because successful exploitation requires only a user to visit a specially crafted URL, making it relatively easy to trigger. The scope of the vulnerability has been updated, indicating a potentially broader impact than initially assessed. This could lead to widespread compromise if not addressed promptly.
CVE-2026-27243 was publicly disclosed on 2026-04-14. While no public proof-of-concept (PoC) has been widely reported, the ease of exploitation associated with reflected XSS vulnerabilities suggests a potential for rapid exploitation. The CVSS score of 9.3 (CRITICAL) highlights the severity of the vulnerability and the potential for significant impact. It is recommended to prioritize remediation efforts.
