GHSA-489g-7rxv-6c8q: MCP Atlassian: DNS-rebinding TOCTOU bypass of the SSRF fix (CVE-2026-27826) 0 The mcp-atlassian package contains a time-of-check to time-of-use (TOCTOU) vulnerability in its SSRF protection mechanism. The vulnerability arises because the SSRF validation resolves and validates the hostname once at middleware time but does not pin the resolved IP address. The actual outbound request re-resolves the hostname at connect time without IP pinning, allowing an attacker-controlled DNS rebinding to bypass the SSRF fix. This can lead to unauthenticated SSRF to internal or cloud metadata services. The vulnerability affects versions prior to 0.22.0. A proof-of-concept demonstrates the structural bypass, though a live exploit requires a DNS rebinding attacker. The severity is high but not critical due to the rebinding race condition precondition.
