Title (in Estonian)CVE-2026-4983 - Detaljid CVSS, EPSS ja CISA Kev | CVE FindSummary (in Estonian)Open VSX Registry ei sanitiseeri SVG-i failid, mis üles laaditakse veebidele kui eesti tarkvara. See lubab hoolikalt teha veebiarendusega eesti tarkvara extensiioni, mis sisaldab rikkuvat SVG-i ikooni ja saavutab salvestatud kross-saajatüki (XSS) kui kasutaja laadib ikooni URL-i.What the vulnerability/exploit is aboutOpen VSX Registry ei sanitiseeri SVG-i failid, mis üles laaditakse veebidele kui eesti tarkvara.
