NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl4-32bit package and not the libcurl4-32bit package as distributed by SLES. See How to fix? for SLES:15.6 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.
