CVE-2024-28224Public exploitNetwork attack vector

Unauthenticated API access via DNS rebinding

Published Apr 8, 2024 · Updated Mar 26, 2025

DNS rebinding in the Ollama HTTP API before 0.1.29 allows remote attackers to access the API through a victim's web browser. The HTTP server did not restrict the Host header to loopback names, so rebinding the page's domain to 127.0.0.1 routed same-origin requests to the unauthenticated local API. A victim must visit attacker-controlled web content; resulting access supports model interaction, local-file disclosure through model creation and pushing, model deletion, and resource-exhaustion denial of service.
