CVE-2026-4983 - Detalji CVSS, EPSS unud Kev | CVE FindSummary (Latvian)CVE-2026-4983 - detaljai CVSS, EPSS unud Kev | CVE FindWhat the vulnerability/exploit is about (Latvian)CVE-2026-4983 - šajā vijom ir problēma ar Open VSX Registry, kas neapstrādā SVG failus, kas tiek ielādēti kā ekspansiņas ikonas, un tās servisā izmanto Content-Type: image/svg+xml bez drošības nosaukumu, piemēram, Content-Security-Policy vai Content-Disposition: attachment. Šī īpašība ļaus atvērt ekspansiņas pakalpojumu ar nebezprotām SVG ikonas un izveido zaudējotāko skaitītāju (XSS) kad lietotājs pēc tam direktā nav ielādējis ikonas URL. Šajā situācijā, kā Open VSX aplikāciju origina, scriptu izpildīšana var būt ar izmantojumu, ko var izmantot atkārtoti, kas var pierakstīt sesiju hijackēšanu, autentifikācijas tokieni pārdod un neizdeva izveidojot nepareizi ekspansiņas pakalpojumus. Šajā situācijā, kā Open VSX aplikāciju origina izmantoja ārējo storīgo (piemēram, open-vsx.org ar S3-backed CDN), izpildīšana ir atkarīga no storīgo origina, samazinot daudzkošu ietekmi, bet vēl arī īpaši var pierakstīt spiežoties un kredēti izveidojot nepareizi ekspansiņas pakalpojumus.Technical explanation for defenders (Latvian)Šajā situācijā, kā Open VSX Registry neapstrādā SVG failus, kas tiek ielādēti kā ekspansiņas ikonas un tās servisā izmanto Content-Type: image/svg+xml bez drošības nosaukumu, piemēram, Content-Security-Policy vai Content-Disposition: attachment, atvērto atvērtāko skaitītāju (XSS) var pierakstīt, kad lietotājs pēc tam direktā nav ielādējis ikonas URL.
