| 제목 | CodeCanyon Perfex CRM 3.2.1 Stored Cross Site Scripting |
|---|
| 설명 | A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Contracts Module of Perfex CRM. This vulnerability permits authenticated client users to inject malicious JavaScript payloads. The input generated by this vulnerability is stored within the contract discussion section and is executed when an administrator accesses the contract. This situation poses significant risks, including the potential for session hijacking, phishing attacks, or the complete compromise of user accounts.
