AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-10-11T12:19:30.605Z and has not been modified since then. LLMGateway through 1.20.0 contains a blind server-side request forgery vulnerability that allows API key holders to reach internal hosts via the video-generation callback_url extension. Attackers can supply loopback, private, or cloud-metadata URLs that deliverWebhook POSTs to without the assertSafeWebhookTarget check, reaching internal services from the worker's network. Defenders should prioritize verifying exposure of LLMGateway instances, especially those with video-generation features enabled, and assess the network

Who should care

Defenders responsible for LLMGateway instances, especially those with video-generation features enabled, should assess their exposure to this vulnerability and prioritize verification and potential remediation.

Why it matters

Defenders should prioritize verifying exposure of LLMGateway instances with video-generation features enabled and assess the network impact of potential SSRF attacks. The vulnerability allows API key holders to reach internal hosts, potentially leading to unauthorized access or data breaches. Remediation involves implementing egress guards or restricting video-generation callback URLs to trusted targets, and monitoring for suspicious activity.

  • Potential unauthorized access to internal services via SSRF
  • Possible data breaches due to unrestricted webhook POSTs
  • Risk of lateral movement within the network
  • Need for verification of LLMGateway instance exposure and remediation

Technical summary

The LLMGateway software through version 1.20.0 contains a blind server-side request forgery (SSRF) vulnerability in its video-generation callback_url extension. This vulnerability allows holders of API keys to access internal hosts by supplying loopback, private, or cloud-metadata URLs that can deliverWebhook POSTs without the assertSafeWebhookTarget check. As a result, internal services can be reached from the worker's network, potentially leading to unauthorized access or data breaches.

Defensive priority

Defenders should prioritize verifying exposure of LLMGateway instances, especially those with video-generation features enabled, and assess the network impact of potential SSRF attacks.

Recommended defensive actions

  • Verify exposure of LLMGateway instances, especially those with video-generation features enabled
  • Assess the network impact of potential SSRF attacks
  • Implement egress guards or restrict video-generation callback URLs to trusted targets
  • Monitor for suspicious video-generation activity and webhook POSTs
  • Perform vulnerability scanning to identify exposed LLMGateway instances
  • Review access controls for video-generation callback URLs
  • Implement additional logging and monitoring for webhook POSTs
