DescriptionCVE.org

Lara Dashboard through 1.3.1 contains a server-side request forgery vulnerability in the POST /api/admin/builder/markdown/fetch endpoint that allows any authenticated user to fetch arbitrary URLs and read the response body. Attackers can read internal HTTP services and cloud metadata including IAM credentials by supplying malicious URLs without host validation or redirect restrictions.

AnalysisAI

Server-side request forgery in Lara Dashboard 0.9.2-1.3.1 allows any authenticated content editor to proxy arbitrary HTTP requests through the application server via the markdown fetch API endpoint, with the server returning response bodies verbatim to the caller. The POST /api/admin/builder/markdown/fetch endpoint validated only URL format (not destination host), enabling requests to internal services and cloud metadata endpoints such as AWS IMDSv1 at 169.254.169.254, which can yield IAM role temporary credentials. …
