Prior to 2.9.1, rendering an attacker-controlled SVG with a path containing many segments can cause quadratic CPU consumption in cairosvg/path.py. The path tokenizer repeatedly slices and rescans the remaining path data, while draw_markers drains node.vertices with node.vertices.pop(0), causing repeated linear-time work. The svg2png, svg2pdf, and svg2ps APIs reach these operations during ordinary rendering, allowing a sub-megabyte SVG to consume substantial CPU and deny service to a rendering application. This issue is fixed in version 2.9.1.","state":0,"publishedAt":"2026-10-08T17:59:09.505+00:00","modifiedAt":"2026-10-08T18:31:17.147+00:00","affected":[{"ecosystem":"Vendor product","name":"CairoSVG","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Kozea\",\n                    \"product\": \"CairoSVG\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.9.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/Kozea/CairoSVG/security/advisories/GHSA-c3jg-qh8m-j3h2","https://github.com/Kozea/CairoSVG/commit/9d63f049f9988d0ddda3eb94564ac3a50a286523","https://github.com/Kozea/CairoSVG/commit/a4d585eb374724b79676e9cceaa9e9a1a4358565","https://github.com/Kozea/CairoSVG/releases/tag/2.9.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107378","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107378","identifiers":["CVE-2026-107378"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
