CVE-2022-4942Network attack vector

Cross-site scripting via unescaped lint messages

Published Apr 20, 2023 · Updated Aug 3, 2024

Cross-site scripting in eslint-detailed-reporter 0.9.0 and earlier allows remote attackers to inject script through lint messages. The renderIssue function inserts message.message into a generated HTML report without escaping it, causing markup in lint output to execute as script. Exploitation requires attacker-controlled lint output and user interaction to open the generated report, enabling modification of its rendered content.
