This can make user B's request get sent over user A's\npreviously authenticated connection.(CVE-2026-19931)\n\nWhen `CURLOPT_PINNEDPUBLICKEY` is configured alongside options that disable\nstandard peer verification (`CURLOPT_SSL_VERIFYPEER = 0` and\n`CURLOPT_SSL_VERIFYHOST = 0`), libcurl fails to enforce public key pinning on\nconnections established without a presented server certificate. Bypassing the\npinning check under these disabled-verification conditions allows\nunauthenticated connections to succeed when they should be rejected.(CVE-2026-80230)\n\nA flaw in libcurl makes it wrongly reuse an existing HTTPS connection setup\nfor a given hostname even when using a different Native CA Store setting\n(`CURLSSLOPT_NATIVE_CA`) than when the connection was created.(CVE-2026-80231)\n\nWhen libpsl support is enabled, libcurl fails to enforce the Public Suffix\nList boundary check when processing a `Set-Cookie` header where the `Domain`\nattribute explicitly matches an origin host that is itself a public suffix\n(e.g., `Domain=co.uk` set by `co.uk`).\n\nInstead of coercing it into a strict host-only cookie, libcurl saves the\ncookie with wildcard domain scope (`.co.uk`). Consequently, the cookie is\ninappropriately included in subsequent outbound requests or HTTP redirects to\narbitrary sibling subdomains under the same public suffix (e.g.,\n`attacker.co.uk`).(CVE-2026-82209)", "category":"general", "title":"Description" }, { "text":"An update for curl is now available for openEuler-20.03-LTS-SP4.\n\nopenEuler Security has rated this update as having a security impact of critical.
