Technical description

The llama-index-core package, up to version 0.12.44, contains a vulnerability in the `get_cache_dir()` function where a predictable, hardcoded directory path `/tmp/llama_index` is used on Linux systems without proper security controls. This vulnerability allows attackers on multi-user systems to steal proprietary models, poison cached embeddings, or conduct symlink attacks. The issue affects all Linux deployments where multiple users share the same system. The vulnerability is classified under CWE-379, CWE-377, and CWE-367, indicating insecure temporary file creation and potential race conditions.

CVE-2026-970263.9 LOW

——0Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.21d CVE-2026-970253.2 LOW

——1Flatpak 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.21d CVE-2026-252658.8 HIG

——2In mlflow/mlflow versions prior to 3.11.0, the `get_or_create_nfs_tmp_dir()` function in `mlflow/utils/file_utils.py` creates temporary directories with world-writable permissions (0o777), and the `_create_model_downloading_tmp_dir()` function in `mlflow/pyfunc/__init__.py` creates directories with group-writable permissions (0o770). These insecure permissions allow local attackers to tamper with model artifacts, such as cloudpickle-serialized Python objects, and achieve arbitrary code execution when the tampered artifacts are deserialized via `cloudpickle.load()`. This vulnerability is particularly critical in environments with shared NFS mounts, such as Databricks, where NFS is enabled by default. The issue is a continuation of the vulnerability class addressed in CVE-2025-10279, which was only partially fixed.88d CVE-2025-34352—

——2JumpCloud Remote Assist for Windows versions prior to 0.317.0 include an uninstaller that is invoked by the JumpCloud Windows Agent as NT AUTHORITY\SYSTEM during agent uninstall or update operations. The Remote Assist uninstaller performs privileged create, write, execute, and delete actions on predictable files inside a user-writable %TEMP% subdirectory without validating that the directory is trusted or resetting its ACLs when it already exists. A local, low-privileged attacker can pre-create the directory with weak permissions and leverage mount-point or symbolic-link redirection to (a) coerce arbitrary file writes to protected locations, leading to denial of service (e.g., by overwriting sensitive system files), or (b) win a race to redirect DeleteFileW() to attacker-chosen targets, enabling arbitrary file or folder deletion and local privilege escalation to SYSTEM. This issue is fixed in JumpCloud Remote Assist 0.317.0 and affects Windows systems where Remote Assist is installed and managed through the Agent lifecycle.2d CVE-2025-49537.4 HIG

——15A flaw was found in Podman. In a Containerfile or Podman, data written to RUN --mount=type=bind mounts during the podman build is not discarded. This issue can lead to files created within the container appearing in the temporary build context directory on the host, leaving the created files accessible.6d
