{"id":"CVE-2025-27608","state":"PUBLISHED","title":"Self Cross-Site Scripting in Arduino IDE","description":"Arduino IDE 2.x is an IDE based on the Theia IDE framework and built with Electron. A Self Cross-Site Scripting (XSS) vulnerability has been identified within the Arduino-IDE prior to version v2.3.5. The vulnerability occurs in the Additional Board Manager URLs field, which can be found in the Preferences -> Settings section of the Arduino IDE interface. In the vulnerable versions, any values entered in this field are directly displayed to the user through a notification tooltip object, without a proper output encoding routine, due to the underlying ElectronJS engine interpretation. This vulnerability exposes the input parameter to Self-XSS attacks, which may lead to security risks depending on where the malicious payload is injected. This vulnerability is fixed in 2.3.5.","publishedAt":"2025-04-02T21:09:16.943Z","updatedAt":"2025-04-03T14:01:53.189Z","severity":{"score":1,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U","source":"GitHub_M"},"assigner":"GitHub_M","products":["arduino arduino-ide"],"affected":[{"vendor":"arduino","product":"arduino-ide","versions":[{"version":"< 2.3.5","status":"affected"}]}],"references":["https://github.com/arduino/arduino-ide/security/advisories/GHSA-252h-4j5q-88pc","https://github.com/arduino/arduino-ide/commit/d298b3ffc94008e89066cd999d891e84190da18f"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:08:47.682Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/27xxx/CVE-2025-27608.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-27608","state":"PUBLISHED","datePublished":"2025-04-02T21:09:16.943Z","dateUpdated":"2025-04-03T14:01:53.189Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-03-03T15:10:34.079Z"},"containers":{"cna":{"title":"Self Cross-Site Scripting in Arduino IDE","descriptions":[{"lang":"en","value":"Arduino IDE 2.x is an IDE based on the Theia IDE framework and built with Electron.
