• 🟠 Known Vulnerabilities:

  • Vulnerabilities in: pkg:maven/com.google.code.gson/[email protected] [CVE-2025-53864] (owasp)
    👌 False positive: gson is used transitively via vaadin-swing-kit-client, but this CVE targets Connect2id Nimbus JOSE + JWT, which is not used in our context.
    · cpe:2.3:a:com.google.code.gson:gson:2.10:::::::*
  • Vulnerabilities in: pkg:maven/com.fasterxml.jackson.core/[email protected] [CVE-2023-35116] (owasp)
    👌 Not a valid CVE report based on the vendor analysis and research
    · cpe:2.3:a:fasterxml:jackson-databind::::::::
  • Vulnerabilities in: pkg:maven/me.friwi/jcef-api@jcef-99c2f7a%2Bcef-127.3.1%2Bg6cbb30e%2Bchromium-127.0.6533.100 [CVE-2024-21639, CVE-2024-21640] (owasp)
    👌 Wait for the update from the jcefmaven community. Meanwhile the swing-kit is supposed to be used with fixed websites and not to browse the internet, we have a check for that, so the only possible attacker would be the same person that created the swing application, aka our customer devs. so this vulnerability is not classified by us as critical issue
