CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

JetBrains Kotlin versions before 1.3.30 were resolving artifacts using an http connection during the build process, potentially allowing an MITM attack.

2) Input validation error (CVE-ID: CVE-2019-10102)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

JetBrains Ktor framework (created using the Kotlin IDE template) versions before 1.1.0 were resolving artifacts using an http connection during the build process, potentially allowing an MITM attack. This issue was fixed in Kotlin plugin version 1.3.30.

3) Input validation error (CVE-ID: CVE-2019-10103)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

JetBrains IntelliJ IDEA projects created using the Kotlin (JS Client/JVM Server) IDE Template were resolving Gradle artifacts using an http connection, potentially allowing an MITM attack. This issue, which was fixed in Kotlin plugin version 1.3.30, is similar to CVE-2019-10101.
