Authenticated internal-service access via crafted card URLs
Published Mar 13, 2026 · Updated Mar 13, 2026
SSRF in Simple Blog Card 2.37 and earlier allows remote authenticated users to send requests from the WordPress server via crafted card URLs. Published sources identify the OGP-fetching request path but do not disclose the exact function or missing validation that permits arbitrary destinations. Contributor-level access is required; successful requests can query or modify reachable internal services, with no reported availability impact.
