{"cve":"CVE-2026-107378","nvd":{"published":"2026-10-08T18:17:23.417","modified":"2026-10-08T21:33:42.423","status":"Awaiting Analysis","description":"CairoSVG is an SVG converter based on Cairo, a 2D graphics library. 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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-407"],"references":["https://github.com/Kozea/CairoSVG/commit/9d63f049f9988d0ddda3eb94564ac3a50a286523","https://github.com/Kozea/CairoSVG/commit/a4d585eb374724b79676e9cceaa9e9a1a4358565","https://github.com/Kozea/CairoSVG/releases/tag/2.9.1","https://github.com/Kozea/CairoSVG/security/advisories/GHSA-c3jg-qh8m-j3h2","https://github.com/Kozea/CairoSVG/security/advisories/GHSA-c3jg-qh8m-j3h2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107378","score":0.00383,"percentile":0.32092,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-c3jg-qh8m-j3h2","url":"https://osv.dev/vulnerability/GHSA-c3jg-qh8m-j3h2","summary":"CairoSVG: Quadratic-time DoS parsing a crafted SVG <path>","modified":"2026-10-15T14:56:21.119947482Z","packages":[{"ecosystem":"PyPI","name":"cairosvg","purl":"pkg:pypi/cairosvg","ranges":["<2.9.1"],"fixed":["2.9.1"]}]},{"id":"PYSEC-2026-4204","url":"https://osv.dev/vulnerability/PYSEC-2026-4204","summary":"CairoSVG: Quadratic-time DoS parsing a crafted SVG <path>","modified":"2026-10-15T14:45:05.910064482Z","packages":[{"ecosystem":"PyPI","name":"cairosvg","purl":"pkg:pypi/cairosvg","ranges":["<2.9.1"],"fixed":["2.9.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
