Multiple SQL vulnerabilities exist in planning.php, user_list.php, projets.php, user_groupes.php, and groupe_list.php in Simple Online Planning (SOPPlanning)before 1.33.

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.

SOPlanning 1.45 has SQL injection via the user_list.php "by" parameter.

SOPlanning before 1.47 has Incorrect Access Control because certain secret key information, and the related authentication algorithm, is public. The key for admin is hardcoded in the installation code, and there is no key for publicsp (which is a guest account).

SOPlanning 1.46.01 allows persistent XSS via the Project Name, Statutes Comment, Places Comment, or Resources Comment field.

SoPlanning before 1.47 doesn't correctly check the security key used to publicly share plannings. It allows a bypass to get access without authentication.

SOPlanning 1.45 is vulnerable to a CSRF attack that allows for arbitrary changing of the admin password via process/xajax_server.php.

SOPlanning 1.45 is vulnerable to a CSRF attack that allows for arbitrary user creation via process/xajax_server.php.

SoPlanning 1.45 is vulnerable to SQL Injection in the OrderBy clause, as demonstrated by the projets.php?order=nom_createur&by= substring.

SOPlanning 1.45 is vulnerable to authenticated SQL Injection that leads to command execution via the users parameter, as demonstrated by export_ical.php.

SOPlanning 1.45 allows XSS via the "Your SoPlanning url" field.

SOPlanning 1.45 allows XSS via the Name or Comment to status.php.

Cross Site Scripting (XSS) vulnerability stored in SOPlanning v1.53.02, which consist of a stored XSS due to a lack of proper validation of user input by sending a POST request using the 'LOGOUT_REDIRECT' parameter in '/soplanning/www/process/options.php'. This vulnerability could allow a remote user to send a specially crafted query to an authenticated user and steal their cookie session details.

SOPlanning is vulnerable to Broken Access Control in /status endpoint. Due to lack of permission checks in Project Status functionality an authenticated attacker is able to add, edit and delete any status. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Predictable Generation of Password Recovery Token. Due to weak mechanism of generating recovery tokens, a malicious attacker is able to brute-force all possible values and takeover any account in reasonable amount of time. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Stored XSS in /groupe_form endpoint. Malicious attacker with medium privileges can inject arbitrary HTML and JS into website, which will be rendered/executed when opening editor. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Stored XSS in /taches endpoint. Malicious attacker with medium privileges can inject arbitrary HTML and JS into website, which will be rendered/executed when opening editor. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Stored XSS in /projets endpoint. Malicious attacker with medium privileges can inject arbitrary HTML and JS into website, which will be rendered/executed when opening edited page. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Stored XSS in /status endpoint. Malicious attacker with an account can inject arbitrary HTML and JS into website, which will be rendered/executed when opening multiple pages. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Privilege Escalation in user management tab. Users with user_manage_team role are allowed to modify permissions of users. However, they are able to assign administrative permissions to any user including themselves. This allow a malicious authenticated attacker with this role to escalate to admin privileges. This issue affects both Bulk Update functionality and regular edition of user's right and privileges. This issue was fixed in version 1.55.

SOPlanning is vulnerable to Stored XSS in /feries endpoint. Malicious attacker with access to public holidays feature is able to inject arbitrary HTML and JS into website, which will be rendered/executed when opening multiple pages. By default only administrators and users with special privileges are able to access this endpoint. This issue was fixed in version 1.55.
