CVE-2026-2532Public exploitNetwork attack vector

Internal-network probing via IPv6-mapped address validation bypass

Published Feb 16, 2026 · Updated Feb 16, 2026

SSRF in DeepAudit 3.0.0 through 3.0.3 allows remote authenticated users to probe internal services via crafted embedding URLs. The IP-address validator in backend/app/api/v1/endpoints/embedding_config.py compares IPv6-mapped IPv4 hosts without normalizing them, so private and loopback destinations bypass the blocked ranges. A valid session and access to the embedding test endpoint are required; response timing reveals whether targeted internal ports accept connections.
