What is CVE-2025-56761?

Memos, an application from UseMemos, is susceptible to Stored Cross Site Scripting (XSS) vulnerabilities in its upload attachment and user avatar features. The software fails to adequately verify the content type of uploaded data, allowing attackers to inject malicious scripts. When an administrator views the stored XSS, an authenticated attacker can leverage this flaw to escalate their privileges, which may jeopardize the application's security. This exposes potential risks for both the application's integrity and its users.
