CVE-2025-64100 – CKAN Vulnerable to Session Cookie Fixation

CVE ID : CVE-2025-64100

Published : Oct. 29, 2025, 6:15 p.m. | 1 hour, 8 minutes ago

Description : CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.9 and 2.11.4, session ids could be fixed by an attacker if the site is configured with server-side session storage (CKAN uses cookie-based session storage by default). The attacker would need to either set a cookie on the victim’s browser or steal the victim’s currently valid session. Session identifiers are now regenerated after each login. This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4

Severity: 6.1 | MEDIUM
