What is CVE-2026-22865?
CVE-2026-22865 is a high-severity vulnerability in gradle, published on 16 Jan 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Gradle is a build automation tool, and its native-platform tool provides Java bindings for native APIs. When resolving dependencies in versions before 9.3.0, some exceptions were not treated as fatal errors and would not cause a repository to be disabled. If a build encountered one of these exceptions, Gradle would continue to the next repository in the list and potentially resolve dependencies from a different repository. An exception like NoHttpResponseException can indicate transient errors. If the errors persist after a maximum number of retries, Gradle would continue to the next repository. This behavior could allow an attacker to disrupt the service of a repository and leverage another repository to serve malicious artifacts. This attack requires the attacker to have control over a repository after the disrupted repository. Gradle has introduced a change in behavior in Gradle 9.3.0 to stop searching other repositories when encountering these errors.
