Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Affected: local-deep-research versions before 1.6.0 are vulnerable to HTML injection in PDF export, because user-supplied research titles and metadata are inserted into the generated HTML without escaping. An authenticated user can submit a crafted query to inject HTML that WeasyPrint processes, which can trigger server-side requests to internal addresses and bypass the application's SSRF validation. Upgrade to version 1.6.0 or later, which adds both HTML escaping and URL validation for PDF resource fetching.
