Multiple Cross-Site Scripting (XSS) vulnerabilities exist in Simple Online Planning (SOPlanning) before 1.33 via the document.cookie in nb_mois and mb_ligness and the debug GET parameter to export.php, which allows malicious users to execute arbitrary code.
Soplanning 1.32 and earlier generates static links for sharing ICAL calendars with embedded login information, which allows remote attackers to obtain a calendar owner's password via a brute-force attack on the embedded password hash.
Directory traversal vulnerability in the file_get_contents function in SOPlanning 1.32 and earlier allows remote attackers to determine the existence of arbitrary files via a .. (dot dot) in a URL path parameter.
The installation process for SOPlanning 1.32 and earlier allows remote authenticated users with a prepared database, and access to an existing database with a crafted name, or permissions to create arbitrary databases, or if PHP before 5.2 is being used, the configuration database is down, and smarty/templates_c is not writable to execute arbitrary php code via a crafted database name.
