No other versions have been reported to be affected, and the vendor or CNA name is not identified in the advisory.", "description_and_impact": "Yaffa version 2.0.0 is susceptible to cross\u2011site scripting when users add an account group. The input that is submitted through the add\u2011account\u2011group form is rendered without any sanitization, enabling an attacker to embed malicious JavaScript that executes in the browser context of anyone who views the affected account\u2011group page. This flaw allows arbitrary code to run with the same privileges as the visitor, potentially enabling session hijacking, credential theft, or further compromise of the system through additional web\u2011based attacks.", "risk_and_exploitability": "Because the flaw permits execution of arbitrary script, the risk is high; the potential impact extends to confidentiality, integrity, and availability of the presenting users\u2019 sessions. No CVSS score is given, but XSS vulnerabilities are widely exploited. Exploitation would most likely occur via a web browser that renders the account\u2011group page, and may require the attacker to obtain or forge inputs through the add\u2011account\u2011group interface. No EPSS data is available, but the commonness of XSS suggests a reasonable likelihood of exploitation."}}}}, "created": "2026-04-08T19:50:17.215915+00:00", "title": "Cross Site Scripting in Yaffa \"Add Account Group\" Feature", "updated": "2026-04-08T19:50:17.215946+00:00", "vendors": [], "weaknesses": ["CWE-79"]}
