Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Certifi versions 2021.5.30 up to but not including 2024.7.4 are affected. The issue is that these versions still trust GLOBALTRUST root certificates, which Mozilla is removing from its trust store after an investigation found long-running, unresolved compliance issues. The source gives few details about any specific attack. Upgrade to certifi 2024.7.4, which removes the GLOBALTRUST roots.
