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)
