Summary
curl vulnerabilities
Details

It was discovered that curl incorrectly handled cookies when redirected from secure to insecure connections. An attacker could possibly use this issue to cause a denial of service, or obtain sensitive information. This issue only affected Ubuntu 25.10. (CVE-2025-9086)

Calvin Ruocco discovered that curl did not properly handle WebSocket communications under certain circumstances. A malicious server could possibly use this issue to poison proxy caches with malicious content. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-10148)

Stanislav Fort discovered that wcurl did not properly handle URLs with certain encoded characters. If a user were tricked into processing a specially crafted URL, an attacker could possibly use this issue to write files outside the intended directory. This issue only affected Ubuntu 25.10. (CVE-2025-11563)

Stanislav Fort discovered that curl did not properly validate pinned public keys under certain circumstances. A remote attacker could possibly use this issue to perform a machine-in-the-middle attack. This issue only affected Ubuntu 25.10.(CVE-2025-13034)

Stanislav Fort discovered that curl did not properly manage TLS options when performing LDAP over TLS transfers in multi-threaded environments. Under certain circumstances, certificate verification could be unintentionally and unknowingly disabled. (CVE-2025-14017)

It was discovered that curl incorrectly handled Oauth2 bearer tokens when following redirects. A remote attacker could possibly use this issue to obtain authentication credentials. (CVE-2025-14524)

Stanislav Fort discovered that curl did not properly validate TLS certificates when reusing connections. A remote attacker could possibly use this issue to bypass expected certificate verification. This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-14819)

Harry Sintonen discovered that curl did not properly validate SSH host keys when performing SSH-based file transfers. This issue could lead to unintended bypass of custom known_hosts file. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15079)

Harry Sintonen discovered that curl built with libssh did not properly handle authentication when performing SSH-based file transfers. This could result in unintended authentication operations. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-15224)

  "details": "It was discovered that curl incorrectly handled cookies when redirected\nfrom secure to insecure connections. An attacker could possibly use this\nissue to cause a denial of service, or obtain sensitive information.\nThis issue only affected Ubuntu 25.10. (CVE-2025-9086)\n\nCalvin Ruocco discovered that curl did not properly handle WebSocket\ncommunications under certain circumstances. 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\npossibly use this issue to perform a machine-in-the-middle attack. This\nissue only affected Ubuntu 25.10.(CVE-2025-13034)\n\nStanislav Fort discovered that curl did not properly manage TLS options\nwhen performing LDAP over TLS transfers in multi-threaded environments.\nUnder certain circumstances, certificate verification could be\nunintentionally and unknowingly disabled. (CVE-2025-14017)\n\nIt was discovered that curl incorrectly handled Oauth2 bearer tokens\nwhen following redirects. 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. This issue could lead to\nunintended bypass of custom known_hosts file. This issue only\naffected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (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)",
