CVE-2019-15074
The Timeline feature in my_view_page.php in MantisBT through 2.21.1 has a stored cross-site scripting (XSS) vulnerability, allowing execution of arbitrary code (if CSP settings permit it) after uploading an attachment with a crafted filename.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
