CVE-2025-40652Network attack vector

Session compromise via unsanitized persisted input

Published May 26, 2025 · Updated May 27, 2025

Stored XSS in CoverManager allows remote attackers to execute JavaScript in a visitor's browser through persisted input. An attacker-controlled value is stored in the platform database and returned without sanitization when the affected page is rendered. No account is required to plant the payload, but a victim must load the page; execution can expose browser-accessible data or perform actions in that victim's session.
