A malicious server could\npossibly use this issue to poison proxy caches with malicious content.\nThis issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10.\n(CVE-2025-10148)\n\nStanislav Fort discovered that wcurl did not properly handle URLs with\ncertain encoded characters. If a user were tricked into processing\na specially crafted URL, an attacker could possibly use this issue to\nwrite files outside the intended directory. This issue only affected\nUbuntu 25.10. (CVE-2025-11563)\n\nStanislav Fort discovered that curl did not properly validate pinned\npublic keys under certain circumstances.

A remote attacker could possibly use this\nissue to obtain authentication credentials. (CVE-2025-14524)\n\nStanislav Fort discovered that curl did not properly validate TLS\ncertificates when reusing connections. A remote attacker could possibly\nuse this issue to bypass expected certificate verification. This issue\nonly affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-14819)\n\nHarry Sintonen discovered that curl did not properly validate SSH host\nkeys when performing SSH-based file transfers.

(CVE-2025-15079)\n\nHarry Sintonen discovered that curl built with libssh did not properly\nhandle authentication when performing SSH-based file transfers. This\ncould result in unintended authentication operations. This issue only\naffected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15224)",
