Title
HumHub 1.19.0 - Stored cross-site scripting in friendship confirmation
Summary
HumHub Community Edition 1.19.0 contains a stored cross-site scripting vulnerability in the friendship confirmation dialog. An authenticated low-privileged member can save HTML in their first and last name. When another authenticated user clicks Friends for that profile, HumHub places the decoded display name into a modal through jQuery html(), causing attacker-controlled markup to execute in the victim's HumHub origin.
