Estado: ModificadaMedia (6.1)—
A vulnerability has been identified in Polarion ALM (All versions < V21 R2 P2), Polarion WebClient for SVN (All versions). A cross-site scripting is present due to improper neutralization of data sent to the web page through the SVN WebClient in the affected product. An attacker could exploit this to execute arbitrary code and extract sensitive information by sending a specially crafted link to users with administrator privileges.
