Description

A flaw was found in langchain-openai. A remote attacker could exploit a Time-of-Check to Time-of-Use (TOCTOU) vulnerability, also known as a DNS rebinding vulnerability. This occurs because the _url_to_size() helper, used for image token counting, validates URLs for Server-Side Request Forgery (SSRF) protection and then fetches them in a separate network operation with independent DNS resolution. This allows an attacker to bypass SSRF protection, potentially leading to unauthorized access to internal resources or information disclosure.
