REDAXO before 5.21.4 contains a stored cross-site scripting vulnerability that allows content editors to inject HTML by storing unescaped values rendered by media, medialist, link and linklist widgets. Attackers can submit crafted REX_INPUT_MEDIA or REX_INPUT_LINK values that break out of the value attribute, executing script in administrators' backend sessions to hijack accounts.
