CVE-2026-97025— Flatpak: flatpak: world-readable oci authentication token in system-helper cache path

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Flatpak 以全局可读权限（0644）将 OCI 仓库的认证令牌写入系统辅助程序的缓存目录，这使得在多台用户共享的系统中，其他本地用户可以读取该令牌，并冒充已认证用户访问 OCI 仓库。仅使用 OCI 源的 Flatpak 配置（例如 Fedora 所使用的配置）受影响；使用 libostree 源的 Flatpak 配置（如 Flathub）不受影响。

Vulnerability Title
Flatpak: flatpak: world-readable oci authentication token in system-helper cache path
Source: CVE Program / CVE List V5
Vulnerability Description
Flatpak writes the OCI repository authentication token with world-readable permissions (0644) in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources (e.g. as used by Fedora) are affected; libostree-based sources such as Flathub are not.
