These vulnerabilities could be exploited by an attacker to achieve information disclosure, bypass security precautions implemented within the application, and execute cross-site scripting (XSS) attacks. Successful exploitation of these vulnerabilities could lead to unauthorized access to sensitive information stored within Gitea repositories, modification of code, or the execution of malicious scripts in the context of other users.
