libcurl is vulnerable to Improper Certificate Validation
37
Low Risk
This Affects:
libcurlTL;DR
An easy handle that first uses the native CA store can keep trusting that store after the application switches the same handle to a custom CA for a later transfer. Connection reuse then accepts a server that the new CA configuration should reject. The fix rebuilds native CA state when the trust configuration changes.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you switch an easy handle from the native CA store to a custom CA.
Background info
libcurl is vulnerable to Improper Certificate Validation in versions 8.17.0 - 8.20.0.
How to fix this
Upgrade the libcurl and/or the curl.curl library to the patch version.
