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

high Tenable Self-Hosted Container Security Plugin ID 465934

Description

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

- When libpsl support is enabled, libcurl fails to enforce the Public Suffix List boundary check when
processing a `Set-Cookie` header where the `Domain` attribute explicitly matches an origin host that is
itself a public suffix (e.g., `Domain=co.uk` set by `co.uk`). Instead of coercing it into a strict host-
only cookie, libcurl saves the cookie with wildcard domain scope (`.co.uk`). Consequently, the cookie is
inappropriately included in subsequent outbound requests or HTTP redirects to arbitrary sibling subdomains
under the same public suffix (e.g., `attacker.co.uk`). (CVE-2026-82209)

Solution

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