Allure Report has an Arbitrary File Read via Path Traversal in Attachment Processing (Allure 1, Allure 2, and XCTest Readers)

Allure 2 is the version 2.x branch of Allure Report, a multi-language test reporting tool. The Allure report generator prior to version 2.38.0 is vulnerable to an arbitrary file read via path traversal when processing test results. An attacker can craft a malicious result file (-result.json, -container.json, or .plist) that points an attachment source to a sensitive file on the host system. During report generation, Allure will resolve these paths and include the sensitive files in the final report. Version 2.38.0 fixes the issue.
