CVE-2024-27290Network attack vector

Stored XSS via unvalidated profile fields

Published Feb 29, 2024 · Updated Aug 5, 2024

Stored XSS in JHPyle docassemble before 1.4.97 allows remote attackers to execute JavaScript in another user’s browser. Profile and registration fields, including the user’s name, accepted HTML and later rendered stored values as markup; the patch adds a BeautifulSoup-based validator that rejects fields containing HTML. Exploitation requires another user to view the stored value, allowing script execution in the docassemble origin with bounded confidentiality and integrity impact.
