CVE-2020-10803: Cross-site Scripting

March 22, 2020 (updated November 2, 2020)

An SQL injection vulnerability was discovered where malicious code could be used to trigger an XSS attack through retrieving and displaying results (in tbl_get_field.php and libraries/classes/Display/Results.php). The attacker must be able to insert crafted data into certain database tables, which when retrieved (for instance, through the Browse tab) can trigger the XSS attack.
