In Craft CMS through 3.1.7, the elevated session password prompt was not being rate limited like normal login forms, leading to the possibility of a brute force attempt on them.

Craft CMS before 3.3.8 has stored XSS via a name field. This field is mishandled during site deletion.

In some circumstances, Craft 2 before 2.7.10 and 3 before 3.2.6 wasn't stripping EXIF data from user-uploaded images when it was configured to do so, potentially exposing personal/geolocation data to the public.

Craft CMS before 3.1.31 does not properly filter XML feeds and thus allowing XSS.

Craft CMS through 3.0.34 allows remote authenticated administrators to read sensitive information via server-side template injection, as demonstrated by a {% string for craft.app.config.DB.user and craft.app.config.DB.password in the URI Format of the Site Settings, which causes a cleartext username and password to be displayed in a URI field.

index.php?p=admin/actions/entries/save-entry in Craft CMS 3.0.25 allows XSS by saving a new title from the console tab.

Craft CMS 2.6.3000 allows remote attackers to execute arbitrary PHP code by using the "Assets->Upload files" screen and then the "Replace it" option, because this allows a .jpg file to have embedded PHP code, and then be renamed to a .php extension.

Craft CMS before 2.6.2982 allows for a potential XSS attack vector by uploading a malicious SVG file.

Craft CMS before 2.6.2976 does not properly restrict viewing the contents of files in the craft/app/ folder.

Craft CMS before 2.6.2976 allows XSS attacks because an array returned by HttpRequestService::getSegments() and getActionSegments() need not be zero-based. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-8052.
