Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Ollama before 0.1.29 has a DNS rebinding vulnerability that can inadvertently allow remote access to the full API, thereby letting an unauthorized user chat with a large language model, delete a model, or cause a denial of service (resource exhaustion).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Ollama before version 0.1.29 is vulnerable to DNS rebinding attacks, which can bypass the localhost binding protection and allow unauthorized remote access to the full API. An attacker can exploit this to interact with LLMs, delete models, or exhaust server resources.

MitigationUpgrade Ollama to version 0.1.29 or later, which includes DNS rebinding protection. Additionally, consider network segmentation and firewall rules to limit API exposure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Ollama version
    Run 'ollama --version' or check the binary version with 'ollama version'
    Affected if Version is below 0.1.29 (e.g., 0.1.28, 0.1.20, etc.)
  2. Verify Ollama process is running
    Run 'ps aux | grep ollama' or check if the ollama service is active
    Affected if Ollama is running and exposed to network
  3. Identify network binding configuration
    Run 'ss -tlnp | grep 11434' or 'netstat -tlnp | grep 11434' to see which address the Ollama API port (default 11434) is listening on
    Affected if Port 11434 is bound to 0.0.0.0 or an external IP rather than 127.0.0.1 only
  4. Test remote API accessibility
    From another machine, run 'curl http://<target-ip>:11434/' to see if the API responds
    Affected if The API responds to requests from a non-localhost IP address

You are affected if Ollama version is below 0.1.29 AND the API port (11434) is accessible from remote hosts rather than bound to localhost only.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 0.1.29 or later
Fixed in 0.1.29
Interim mitigation

Upgrade Ollama to version 0.1.29 or later, which includes DNS rebinding protection. Additionally, consider network segmentation and firewall rules to limit API exposure.

Recommended fix Moderate confidence

Ollama version 0.1.29 or later

  1. Check the current installed version of Ollama by running 'ollama --version'
  2. Stop the Ollama service if it is currently running
  3. Upgrade Ollama to version 0.1.29 or a later version. For example, on systems with automatic updates, ensure the package manager pulls the latest version. For manual installations, download and install the updated binary from the official Ollama releases
  4. Restart the Ollama service after the upgrade
  5. Verify the installed version is 0.1.29 or later using 'ollama --version'
