CVE-2018-16249

In Symphony before 3.3.0, there is XSS in the Title under Post.

MEDIUM 4.8EPSS 0.52%

Does this matter?

Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.

Description

In Symphony before 3.3.0, there is XSS in the Title under Post. The ID "articleTitle" of this is stored in the "articleTitle" JSON field, and executes a payload when accessing the /member/test/points URI, allowing remote attacks. Any Web script or HTML can be inserted by an admin-authenticated user via a crafted web site name.
