**Name of the Vulnerable Software and Affected Versions** libcurl (affected versions not specified) **Description** When reusing a handle for sequential transfers driven by environment-variable proxy configuration, the software fails to clear the proxy authentication state between requests. If an initial transfer authenticates against a proxy using Digest authentication, a subsequent transfer routed through a different proxy erroneously leaks the `Proxy-Authorization:` header intended for the first proxy. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
