CVE-2020-13133Network attack vector

Browser script execution via stored administrator payload

Published Jan 20, 2021 · Updated Aug 4, 2024

Stored XSS in Tufin SecureChange before R19.3 HF3 and R20-1 HF1 allows attackers to execute script when stored content is viewed. Public records do not identify the affected input, storage field, or rendering path, so the precise missing validation or output-encoding operation is undisclosed. An administrator must store the payload, but an unauthenticated user can trigger it; execution is limited to the viewing user's browser context.
