    Published: 31 Dec 2023Last Modified: 9 Jul 2026

    Summary:

    Details: Sympa before 6.2.62 relies on a cookie parameter for certain security objectives, but does not ensure that this parameter exists and has an unpredictable value. Specifically, the cookie parameter is both a salt for stored passwords and an XSS protection mechanism.
