Summary

fpdf2 prior to 2.8.8 automatically dereferences attacker-controlled HTTP(S) URLs and raw local paths supplied through FPDF.image(), FPDF.write_html() HTML <img src> values, SVG <image href> or xlink:href values, and template image fields. This can cause outbound requests to attacker-selected internal or external services and local file open attempts.

Risk Assessment

An attacker could use the application to scan internal networks or disclose local file contents if they are valid images or SVG resources. The risk mainly affects applications generating PDFs from untrusted input.

Recommendation

Update fpdf2 to version 2.8.8 or later. Additionally, consider restricting access to network and local resources in the context of the PDF-generating application.

Other vulnerabilities in fpdf2

CVE-2026-114610Medium
fpdf2 is a PDF creation library for Python. From 2.5.0 until 2.8.8, SVGObject.build_xref() passes nested SVG <use> references to GraphicsContext.add_item(), whose default clone=True deep-copy behavior copies the complete referenced graphics tree during FPDF.image() processing. Repeating references at each nesting level makes in-memory object count and processing work grow exponentially, allowing a small user-controlled SVG to consume excessive CPU and memory, raise MemoryError, fail PDF generation jobs, and exhaust worker capacity. ResourceAccessPolicy does not prevent the issue because the references are inline and require no external resource.

Original NVD description (English source)

fpdf2 is a PDF creation library for Python. Prior to 2.8.8, fpdf2's shared image loader automatically dereferences attacker-controlled HTTP(S) URLs and raw local paths supplied through FPDF.image(), FPDF.write_html() HTML <img src> values, SVG <image href> or xlink:href values, and template image fields. This can cause outbound requests to attacker-selected internal or external services and local file open attempts, although local content is exposed only when it is a valid supported image or SVG resource. file:// URLs are not specially handled, so the local-path case requires a raw filesystem path. This issue is fixed in version 2.8.8.
