Common questions

How do I fix CVE-2024-39468?

Published advisories record a fix for 130 affected products. The "How to fix" section on this page lists the fixed version and source advisory for each one, so apply the entry matching what you actually run.

Is CVE-2024-39468 being actively exploited?

Not that we know of. CVE-2024-39468 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.53% is the estimated probability that it will be exploited in the next 30 days. That is higher than 42% of all scored CVEs.

How severe is CVE-2024-39468?

CVE-2024-39468 has a CVSS v3 base score of 7.5, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.
