How to fix?

Upgrade SLES:16.0.0 libcurl4 to version 8.14.1-160000.8.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl4 package and not the libcurl4 package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

When reusing a libcurl handle for sequential transfers driven by environment-variable proxy configuration, libcurl fails to clear the proxy authentication state between requests. Specifically, if the initial transfer authenticates against proxyA using Digest auth, a subsequent transfer routed through proxyB erroneously leaks the Proxy-Authorization: header intended solely for proxyA.
