CVE-2026-3577 identifies a Stored Cross-Site Scripting (XSS) vulnerability in the Keep Backup Daily plugin for WordPress, affecting all versions up to 2.1.2. This medium-severity flaw (CVSS 4.4) allows authenticated attackers with Administrator-level access to inject arbitrary web scripts via the backup title alias due to insufficient input sanitization and output escaping. These scripts execute when another administrator views the backup list page, potentially leading to client-side compromise. Exploitation requires high attack complexity due to the necessary privileges. There is currently no evidence of active exploitation, public exploit code, or significant community discussion regarding this vulnerability.
