Summary
OAUTH2 bearer bypass in connection reuse
Details

libcurl might reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMTP(S), IMAP(S), POP3(S) and LDAP(S) (OpenLDAP only).

libcurl maintains a pool of live connections after a transfer has completed (sometimes called the connection cache). This pool of connections is then gone through when a new transfer is requested and if there is a live connection available that can be reused, it is preferred instead of creating a new one.

Due to this security vulnerability, a connection that is successfully created and authenticated with a username + OAUTH2 bearer could subsequently be erroneously reused even for user + [other OAUTH2 bearer], even though that might not even be a valid bearer. This could lead to an authentication bypass, either by mistake or by a malicious actor.
