A PHP injection vulnerability in Spip before v3.2.8 allows attackers to execute arbitrary PHP code via the _oups parameter at /ecrire.

Multiple cross-site scripting (XSS) vulnerabilities in the component /spip.php of Spip Web Framework v3.1.13 and below allows attackers to execute arbitrary web scripts or HTML.

SPIP before 3.2.14 and 4.x before 4.0.5 allows unauthenticated access to information about editorial objects.

SPIP before 3.2.14 and 4.x before 4.0.5 allows remote authenticated editors to execute arbitrary code.

SPIP 4.0.0 is affected by a remote command execution vulnerability. To exploit the vulnerability, an attacker must craft a malicious picture with a double extension, upload it and then click on it to execute it.

SPIP 4.0.0 is affected by a Cross Site Request Forgery (CSRF) vulnerability in ecrire/public/aiguiller.php, ecrire/public/balises.php, ecrire/balise/formulaire_.php. To exploit the vulnerability, a visitor must visit a malicious website which redirects to the SPIP website. It is also possible to combine XSS vulnerabilities in SPIP 4.0.0 to exploit it. The vulnerability allows an authenticated attacker to execute malicious code without the knowledge of the user on the website (CSRF).

SPIP 4.0.0 is affected by a Cross Site Scripting (XSS) vulnerability in ecrire/public/interfaces.php, adding the function safehtml to the vulnerable fields. An editor is able to modify his personal information. If the editor has an article written and available, when a user goes to the public site and wants to read the author's information, the malicious code will be executed. The "Who are you" and "Website Name" fields are vulnerable.

SPIP 4.0.0 is affected by a Cross Site Scripting (XSS) vulnerability. To exploit the vulnerability, a visitor must browse to a malicious SVG file. The vulnerability allows an authenticated attacker to inject malicious code running on the client side into web pages visited by other users (stored XSS).

The official spiped docker images before 1.5-alpine contain a blank password for a root user. Systems using the spiped docker container deployed by affected versions of the docker image may allow an remote attacker to achieve root access with a blank password.

prive/formulaires/configurer_preferences.php in SPIP before 3.2.8 does not properly validate the couleur, display, display_navigation, display_outils, imessage, and spip_ecran parameters.
