Stored XSS via unsanitized family names
Published Jun 13, 2024 · Updated Aug 2, 2024
Stored XSS in ChurchCRM 5.8.0 allows remote attackers to execute script in users' browsers through an externally registered family name. The registration flow stores the Family Name payload without neutralizing its HTML, and the Family page renders it as active markup. Exploitation requires open external registration and an authenticated user to visit the Family page, where the script runs with that user's application context.
