MEDIUM 5.1EPSS 0.17%
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
SPIP before 4.4.8 allows cross-site scripting (XSS) in the private area via malicious iframe tags. The application does not properly sandbox or escape iframe content in the back-office, allowing an attacker to inject and execute malicious scripts. The fix adds a sandbox attribute to iframe tags in the private area. This vulnerability is not mitigated by the SPIP security screen.
