CVE-2025-64100

CVE-2025-64100 is a medium-severity security vulnerability in ckan (pip), affecting versions >= 2.10.0, < 2.10.9. It is fixed in 2.10.9, 2.11.4.

Impact

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.

CVE-2025-64100 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.10.9, 2.11.4); upgrading removes the vulnerable code path.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions

  1. What is CVE-2025-64100? CVE-2025-64100 is a medium-severity security vulnerability in ckan (pip), affecting versions >= 2.10.0, < 2.10.9. It is fixed in 2.10.9, 2.11.4.
  2. How severe is CVE-2025-64100? CVE-2025-64100 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
  3. Which versions of ckan are affected by CVE-2025-64100? ckan (pip) versions >= 2.10.0, < 2.10.9 is affected.
  4. Is there a fix for CVE-2025-64100? Yes. CVE-2025-64100 is fixed in 2.10.9, 2.11.4. Upgrade to this version or later.
  5. Is CVE-2025-64100 exploitable, and should I be worried? Whether CVE-2025-64100 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

  6. What actually determines whether CVE-2025-64100 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
  7. How do I fix CVE-2025-64100?
    • Upgrade ckan to 2.10.9 or later
    • Upgrade ckan to 2.11.4 or later
