Privilege escalation via unsanitized SVG upload
Published Nov 19, 2024 · Updated Jul 5, 2026
Stored XSS in REDAXO Core CMS before 5.18.0 allows remote authenticated users to execute script in an administrator's browser. The mediapool stores uploaded SVG files without removing embedded JavaScript, which runs when an administrator opens the file. The attacker needs mediapool upload permission and administrator interaction; the script can steal cookies or change the administrator's password.
