Stored XSS via unsanitized Default Keyword setting
Published Apr 19, 2024 · Updated Aug 2, 2024
Stored XSS in CSZ CMS 1.3.0 allows remote authenticated users to run script in a visitor's browser through the Default Keyword field. The Site Settings handler saves a crafted Default Keyword value, and site pages later render that value without neutralizing injected markup. The attacker needs settings access and a visitor must load the affected site; the script then runs in that visitor's site origin and can read or modify browser-accessible data.
