MEDIUM 4.8EPSS 0.20%

Does this matter?

Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.

Description

SPIP before 4.2.15 allows Cross-Site Scripting (XSS) via crafted content in HTML code tags. The application does not properly verify JavaScript within code tags, allowing an attacker to inject malicious scripts that execute in a victim's browser.
