Description Robb Gatica 2023-10-11 23:52:44 UTC 
The CSV grade import method contained an XSS risk for users importing the spreadsheet, if it contained unsafe content. The suggested workaround was to verify the contents and trustworthiness of grade spreadsheets before importing them. This flaw affects versions 4.2 to 4.2.2, 4.1 to 4.1.5, 4.0 to 4.0.10, 3.11 to 3.11.16, 3.9 to 3.9.23 and earlier unsupported versions.
