HIGH 7.5REMOTEUPGRADE

CVE-2025-6209 is a high-severity flaw (CVSS 7.5) affecting llamaindex. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A path traversal vulnerability exists in run-llama/llama_index versions 0.12.27 through 0.12.40, specifically within the `encode_image` function in `generic_utils.py`. This vulnerability allows an attacker to manipulate the `image_path` input to read arbitrary files on the server, including sensitive system files. The issue arises due to improper validation or sanitization of the file path, enabling path traversal sequences to access files outsid

llamaindex llamaindex UPGRADE

Affected: >= 0.12.27 and < 0.12.41

Fixed in: 0.12.41

Safe to downgrade to: a release before 0.12.27

1. Check installed version

apt-cache policy llamaindex || rpm -q llamaindex || llamaindex --version

2. UPGRADE to 0.12.41 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade llamaindex

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade llamaindex

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 0.12.27 (Debian / Ubuntu)

apt-cache madison llamaindex sudo apt install llamaindex=<VERSION_BEFORE_0.12.27> sudo apt-mark hold llamaindex

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list llamaindex sudo dnf downgrade llamaindex-<VERSION_BEFORE_0.12.27> sudo dnf versionlock add llamaindex

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
