Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-73 and the CVSS impact.

Summary

pdfmake from 0.3.8 before 0.3.12 does not apply the setLocalAccessPolicy() restriction to images referenced inside SVG content. An attacker who supplies a document definition can add an SVG image href that points to a local path, so restricted file contents are embedded in the generated PDF. The weakness is classified as CWE-73, External Control of File Name or Path. An unauthenticated remote attacker can exploit this with low complexity and no user interaction.
