Routine

MEDIUM 4.9UPGRADE

CVE-2026-77825 is a medium-severity flaw (CVSS 4.9) affecting contextforge. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

IBM ContextForge MCP Gateway 1.0.0 through 1.0.8 was vulnerable to path traversal in its Admin API log-download endpoint (`GET /v1/admin/logs/file`). The path confinement check uses `str.startswith()` rather than proper boundary validation, allowing an authenticated admin to read `.log`, `.jsonl`, and `.json` files outside the configured `LOG_FOLDER` by supplying a filename that resolves into a sibling directory whose absolute path shares the log

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

ibm contextforge UPGRADE

Affected: >= 1.0.0 and < 1.0.9

Fixed in: 1.0.9

Safe to downgrade to: a release before 1.0.0

1. Check installed version

pip show contextforge

2. UPGRADE to 1.0.9

pip install --upgrade "contextforge>=1.0.9"

3. If no update is available yet, DOWNGRADE to a release before 1.0.0

pip index versions contextforge pip install "contextforge<1.0.0"

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.
