CVE-2026-96276Source published Source updated
If a malicious SDK container declares an extension point with a crafted `directory` path, and a developer runs `flatpak build-init --writable-sdk --sdk-extension` with that SDK, attacker-chosen files could be written outside the working directory, since the target path is resolved via a function that allows `..` traversal. Red Hat estimates the CVSSv3.1 vector of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N. The SDK content is retrieved from a remote registry, so no local access to the victim's system is required by the attacker (AV:N), and the attacker needs no privileges of their own (PR:N). Once the developer builds against the malicious SDK, exploitation is deterministic: the extension point's directory field is resolved via g_file_resolve_relative_path, which does not reject..…
