libcurl is vulnerable to Improper Certificate Validation
37
Low Risk
This Affects:
libcurlTL;DR
A transfer that upgrades a connection with STARTTLS can reuse an existing live connection whose TLS settings do not match the new request. The reused connection skips the TLS configuration the new transfer asked for. The fix refuses reuse when the STARTTLS configuration does not match.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you reuse connections for protocols that upgrade with STARTTLS.
Background info
libcurl is vulnerable to Improper Certificate Validation in versions 7.30.0 - 8.20.0.
How to fix this
Upgrade the libcurl and/or the curl.curl library to the patch version.
