Summary
CVE-2025-52552 affects FastGPT, an AI Agent building platform, before version 4.9.12. The LastRoute parameter on the login page is vulnerable to open redirect (CWE-601) and DOM-based cross-site scripting (CWE-79). Because the parameter is improperly validated and not sanitized, attackers can run malicious JavaScript or redirect users to attacker-controlled sites.
Mitigation
Fixed in version 4.9.12.
