CVE-2026-114609
MEDIUM5.8

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 values, SVG 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.

CVE-2026-114610
MEDIUM6.5

fpdf2 is a PDF creation library for Python. From 2.5.0 until 2.8.8, fpdf2's SVGObject.build_xref() passes nested SVG 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 the 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 reduce or exhaust worker capacity. ResourceAccessPolicy does not prevent the issue because the references are inline and require no external resource, XML entity, local file, or permissive network setting. This issue is fixed in version 2.8.8.
