Summary

PDFMathTranslate (pdf2zh) through 1.9.11 contains a server-side request forgery vulnerability that allows unauthenticated attackers to make the server fetch arbitrary URLs via the Link input. The translate_file handler passes user URLs to download_with_limit without scheme or address validation, letting attackers reach internal services and cloud metadata endpoints and retrieve returned PDFs.

Risk Assessment

The risk includes access to internal resources and cloud metadata, potentially leading to leakage of sensitive information and further attacks.

Recommendation

Upgrade PDFMathTranslate to a version newer than 1.9.11 and implement URL validation in download_with_limit, blocking private addresses and cloud metadata.
