Description
Certifi is a curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. Certifi starting in 2021.5.30 and prior to 2024.7.4 recognized root certificates from GLOBALTRUST. Certifi 2024.7.04 removes root certificates from GLOBALTRUST from the root store. These are in the process of being removed from Mozilla's trust store. GLOBALTRUST's root certificates are being removed pursuant to an investigation which identified "long-running and unresolved compliance issues."

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for certifi, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update certifi to 2024.7.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-39689 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
Red Hat ships an affected version of python-certifi; however, the product includes a separate CA bundle installed from RHEL with a custom product-based patch. Hence it is not using the certificates provided upstream and not affected by the flaw. Red Hat Product Security team does not foresee any impact on the…
This issue can be mitigated by adding the root CAs in question to /etc/pki/ca-trust/source/blacklist on RHEL 8 or /etc/pki/ca-trust/source/blocklist on RHEL 9 and running update-ca-trust.
