ConnectWise PSA vulnerabilities

In ConnectWise PSA versions older than 2026.1, certain session cookies were not set with the HttpOnly attribute. In some scenarios, this could allow client-side scripts access to session cookie values.

In ConnectWise PSA versions older than 2026.1, Time Entry notes stored in the Time Entry Audit Trail may be rendered without applying output encoding to certain content. Under specific conditions, this may allow stored script code to execute in the context of a user’s browser when the affected content is displayed.
