Echo: curl: security update to 1:8.22.0-1+e1

critical Tenable Cloud Security Plugin ID 462589

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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`. (CVE-2026-8927)

Solution

Update the curl library and its related packages to version 1:8.22.0-1+e1 or later.
