Security fixes:
- Cross-Site Scripting (XSS) via malicious HTML content
- CSRF attack can cause an authenticated user to be logged out
- Remote code execution via crafted config options
- Path traversal vulnerability allowing local file inclusion via crafted
'plugins' option
The latter two vulnerabilities are classified minor because they only
affect Roundcube installations with public access to the Roundcube
installer. That’s generally a high-risk situation and is expected to be
rare or practically non-existent in productive Roundcube deployments.
However, the fixes are done in core in order to also prevent from future
and yet unknown attack vectors.
