Apache Gravitino 1.2.1 SSRF (CVE‑2026‑49876) Enables Authenticated Internal‑Network Access
What Happened – A Server‑Side Request Forgery (SSRF) flaw was disclosed in Apache Gravitino 1.0.0‑1.2.1 (CVE‑2026‑49876). The vulnerable fetchFileFromUri() method accepts arbitrary http/https/ftp URLs from job‑template fields and downloads them without validation, allowing an authenticated attacker to force the server to request internal resources or cloud‑metadata endpoints.
Why It Matters for Compliance & Audit Readiness
- Demonstrates the need for continuous vulnerability management and timely patching to satisfy SOC 2 CC6.1 (Risk Management) and CC7.1 (System Operations).
- Highlights gaps in network segmentation and egress monitoring that SOC 2 CC6.2 (Logical Access) expects organizations to evidence.
- Provides a concrete example of why control mapping & continuous evidence collection are essential to prove that security controls are operating as designed.
Who Is Affected – Enterprises that run Gravitino as a data‑catalog / governance layer, especially in cloud‑native environments (e.g., data‑lake, analytics, and AI platforms).
Recommended Actions
- Apply the upstream patch (see Apache advisory) or upgrade to ≥ 1.2.2.
- Enforce strict validation of all URI inputs in job templates; deny non‑whitelisted schemes.
- Deploy egress firewalls or cloud‑metadata protection (e.g., AWS IMDSv2) and log outbound requests for SOC 2 evidence.
- Update your SOC 2 control inventory to include “SSRF mitigation” under Vulnerability Management and Network Segmentation.

Technical Notes – The flaw resides in JobManager.java → fetchFileFromUri(). It uses Apache Commons FileUtils.copyURLToFile() without destination checks. CVE‑2026‑49876 is rated CVSS 8.6 (High). Exploitation requires a valid Gravitino user with job‑template privileges.
