Detailsinfo

A vulnerability has been found in Stirling-Tools Stirling-PDF up to 2.x and classified as problematic. Affected by this vulnerability is some unknown functionality of the component create-pdf-from-html-agent. The manipulation of the argument htmlContent with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality. The summary by CVE is:

Stirling-PDF is a locally hosted web application that facilitates various operations on PDF files. Prior to 3.0.0, POST /api/v1/ai/tools/create-pdf-from-html-agent accepts attacker-controlled htmlContent and passes it to WeasyPrint without CustomHtmlSanitizer, unlike the sanitized /api/v1/convert/html/pdf control path. HTTP and HTTPS resource references can make server-side requests to internal or cloud-metadata destinations, while file references can embed local content readable by the Stirling-PDF process into the generated PDF. The endpoint is reachable without credentials when security.enableLogin is false, and the flaw is distinct from earlier Stirling-PDF WeasyPrint vulnerabilities in older conversion paths. This issue is fixed in version 3.0.0.
