CVE-2022-29817

Browser-context script execution via reflected error messages

Published Apr 28, 2022 · Updated Aug 3, 2024

Reflected XSS in JetBrains IntelliJ IDEA before 2022.1 allows local users to run script in an IDE browser context via server errors. The internal web server reflects attacker-controlled request content into rendered error messages without adequate output neutralization; JetBrains has not disclosed the responsible function. The required low-privileged local access and user interaction bound the impact to reading or changing data within the affected browser context.
