Short explanation
REDAXO from version 5.18.0 before 5.21.4 contains a stored cross-site scripting vulnerability because rex_media_service moves uploaded SVG files into the public media folder before sanitizing them.
Authenticated users with mediapool upload rights can race the sanitizer or exhaust memory limits to leave script-laden SVGs publicly served. This executes malicious scripts within victims' backend sessions.
What should be done?
- Follow vendor advisories to check for updates
- Review user permissions and mediapool upload rights
- Apply guidance provided by the vendor where applicable
