Technical details

The vulnerability exists due to improper HTML sanitization in the removeHTML utility function, which failed to drop unclosed tags (such as <img src=x), combined with the main menu rendering the weblog description without HTML escaping. An authenticated weblog administrator can inject script via the weblog description field, which is then stored and executed client-side when members access the menu. The fix removes unclosed tags during sanitization and renders the description as plain text rather than HTML.
