Youssouf Boulouiz discovered that SPIP incorrectly handled login error
messages. A remote attacker could potentially exploit this to conduct
cross-site scripting (XSS) attacks. (CVE-2019-16392)

Gilles Vincent discovered that SPIP incorrectly handled password reset
requests. A remote attacker could possibly use this issue to cause SPIP to
enumerate registered users. (CVE-2019-16394)

Guillaume Fahrner discovered that SPIP did not properly sanitize input. A
remote authenticated attacker could possibly use this issue to execute
arbitrary code on the host server. (CVE-2019-11071)

Sylvain Lefevre discovered that SPIP incorrectly handled user
authorization. A remote attacker could possibly use this issue to modify
and publish content and modify the database. (CVE-2019-16391)

It was discovered that SPIP did not properly sanitize input. A remote
attacker could, through cross-site scripting (XSS) and PHP injection,
exploit this to inject arbitrary web script or HTML. (CVE-2017-15736)

Alexis Zucca discovered that SPIP incorrectly handled the media plugin. A
remote authenticated attacker could possibly use this issue to write to
the database. (CVE-2019-19830)

Christophe Laffont discovered that SPIP incorrectly handled redirect URLs.
An attacker could use this issue to cause SPIP to crash, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2019-16393)
