KDE : Security Vulnerabilities, CVEs, (Bypass) CVSS score >= 8

KMail since version 5.3.0 used a QWebEngine based viewer that had JavaScript enabled. Since the generated html is executed in the local file security context by default access to remote and local URLs was enabled.

The %{password(...)} macro in pastemacroexpander.cpp in the KDE Paste Applet before 4.10.5 in kdeplasma-addons does not properly generate passwords, which allows context-dependent attackers to bypass authentication via a brute-force attack.
