Fpdf2: Exponential SVG '<use>' Expansion Causes CPU And Memory Exhaustion In 'FPDF.image()'

Summary fpdf2 expands SVG "" references by deep-copying the complete referenced graphics tree. A small SVG can use nested references to make the number of in-memory objects grow exponentially, causing excessive CPU and memory consumption during "FPDF.image" processing. This was reproduced with an...

Fpdf2 Implicitly Loads External URLs And Local Image Paths When Rendering Attacker-controlled Content

Summary "fpdf2" implicitly dereferences image resource references supplied to rendering APIs. If an application passes untrusted HTML, SVG, template data, or image paths into those APIs, "fpdf2" may issue outbound HTTPS requests or attempt to open local filesystem paths. This behavior is relevant...

Linux Distros Unpatched Vulnerability : CVE-2026-114609

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fpdf2 is a PDF creation library for Python. Prior to 2.8.8, fpdf2's shared image loader automatically dereferences attacker-controlled HTTPS URLs and raw local...

CVE-2026-114609

fpdf2 is a PDF creation library for Python. Prior to 2.8.8, fpdf2's shared image loader automatically dereferences attacker-controlled HTTPS URLs and raw local paths supplied through FPDF.image, FPDF.writehtml HTML values, SVG or xlink:href values, and template image fields. This can cause outbou...

CVE-2026-114610 fpdf2: Exponential SVG '<use>' expansion causes CPU and memory exhaustion in 'FPDF.image()'

fpdf2 is a PDF creation library for Python. From 2.5.0 until 2.8.8, fpdf2's SVGObject.buildxref passes nested SVG references to GraphicsContext.additem, whose default clone=True deep-copy behavior copies the complete referenced graphics tree during FPDF.image processing. Repeating references at...

CVE-2026-114610

The Python PDF creation library fpdf2 versions 2.5.0 through 2.8.8 is vulnerable to CPU and memory exhaustion during FPDF.image() processing. The root cause lies in SVGObject.build_xref() passing nested SVG references to GraphicsContext.add_item() . Because the default clone=True behavior perfor...

py-pdf fpdf2 server request forgery vulnerability

Versions of py-pdf fpdf2 prior to 2.8.8 contain a server-side request forgery vulnerability. This vulnerability arises because the shared image loader automatically dereferences HTTPS URLs and original local paths provided by attackers; these paths originate from HTML img src values, SVG image hr...
