Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of certifi from 2015.4.28 before 2023.7.22 include root certificates from e-Tugra, which are being removed from Mozilla's trust store after an investigation into security issues at e-Tugra. The source gives few details about what an attacker could do with these certificates. Upgrade certifi to 2023.7.22, which removes the e-Tugra root certificates.
