SPIP before 3.1.11 and 3.2 before 3.2.5 provides different error messages from the password-reminder page depending on whether an e-mail address exists, which might help attackers to enumerate subscribers.
Cross-site scripting (XSS) vulnerability (stored) in SPIP before 3.1.7 allows remote attackers to inject arbitrary web script or HTML via a crafted string, as demonstrated by a PGP field, related to prive/objets/contenu/auteur.html and ecrire/inc/texte_mini.php.
The SPIP template composer/compiler in SPIP 3.1.2 and earlier allows remote authenticated users to execute arbitrary PHP code by uploading an HTML file with a crafted (1) INCLUDE or (2) INCLURE tag and then accessing it with a valider_xml action.
ecrire/exec/valider_xml.php in SPIP 3.1.2 and earlier allows remote attackers to conduct server side request forgery (SSRF) attacks via a URL in the var_url parameter in a valider_xml action.
Cross-site request forgery (CSRF) vulnerability in ecrire/exec/valider_xml.php in SPIP 3.1.2 and earlier allows remote attackers to hijack the authentication of administrators for requests that execute the XML validator on a local file via a crafted valider_xml request. NOTE: this issue can be combined with CVE-2016-7998 to execute arbitrary PHP code.
Cross-site scripting (XSS) vulnerability in valider_xml.php in SPIP 3.1.2 and earlier allows remote attackers to inject arbitrary web script or HTML via the var_url parameter in a valider_xml action.
Directory traversal vulnerability in ecrire/exec/valider_xml.php in SPIP 3.1.2 and earlier allows remote attackers to enumerate the files on the system via the var_url parameter in a valider_xml action.
