AnalysisAIv1 – Mar 12, 2026

OpenSift versions prior to 1.6.3-alpha are vulnerable to server-side request forgery (SSRF) attacks through the URL ingest pipeline, which fails to properly validate credentialed URLs, non-standard ports, and cross-host redirects in non-localhost deployments. An unauthenticated remote attacker can exploit this to access internal resources and potentially exfiltrate sensitive data from the affected system. No patch is currently available for this vulnerability.

v1 Mar 12, 2026 - 22:06 CVSS 8.2

OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI. versions up to 1.6.3 is affected by server-side request forgery (ssrf) (CVSS 8.2).

RemediationAI

Fixed in version 1.6.3. Restrict network access to the affected service where possible.

This vulnerability (CWE-918: Server-Side Request Forgery (SSRF)) affects OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI.. OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI. Prior to version 1.6.3-alpha, the URL ingest pipeline accepted user-controlled remote URLs with incomplete destination restrictions. Although private/local host checks existed, missing restrictions for credentialed URLs, non-standard ports, and cross-host redirects left SSRF-class abuse paths in non-localhost deployments. This issue has been patched in version 1.6.3-alpha.

DescriptionGitHub Advisory

OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI. Prior to version 1.6.3-alpha, the URL ingest pipeline accepted user-controlled remote URLs with incomplete destination restrictions. Although private/local host checks existed, missing restrictions for credentialed URLs, non-standard ports, and cross-host redirects left SSRF-class abuse paths in non-localhost deployments. This issue has been patched in version 1.6.3-alpha.

Executive ViewAI

Why It Matters

OpenShift deployments running versions prior to 1.6.3-alpha are vulnerable to Server-Side Request Forgery (SSRF) attacks through the URL ingest pipeline, potentially allowing attackers to access internal systems, exfiltrate sensitive data, or pivot to backend infrastructure. This vulnerability poses immediate risk to organizations using OpenShift for AI-driven data analysis, particularly those handling sensitive datasets or operating in regulated environments.

Business Impact: High
Compensating Controls

Disable the URL ingest pipeline feature entirely if not critical to operations. Implement network segmentation preventing OpenShift from reaching internal systems, private IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16), and metadata services. Deploy WAF rules blocking requests to non-standard ports and credential-based URLs. Restrict outbound connections to whitelisted external domains only. Monitor and log all URL ingest requests for suspicious patterns. Implement rate limiting on the ingest endpoint.
