NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl-devel package and not the libcurl-devel package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI transfers and could potentially result in unauthorized access to sensitive information. The safest option is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.
