CyberRota Analysis
AI-GeneratedUnleash versions prior to 8.0.3 are vulnerable due to improper handling of Mustache template escaping, allowing an editor-level user to inject malicious links into trusted outbound notifications such as Slack or Microsoft Teams. This could lead to phishing attacks or other malicious activities targeting users who receive these notifications. Organizations using Unleash for feature management should prioritize upgrading to version 8.0.3 to mitigate this risk.

Original NVD Description
Unleash is an open-source feature management platform. Prior to 8.0.3, FeatureEventFormatterMd.format in src/lib/addons/feature-event-formatter-md.ts assigns Mustache.escape to an identity function before rendering action and path templates. Because Mustache.escape is process-wide, the assignment disables escaping for subsequent Mustache.render calls in email-service.ts, webhook.ts, datadog.ts, and new-relic.ts. An editor-level user can place Slack or Microsoft Teams link syntax in an unrestricted username, trigger a feature event, and inject an attacker-labeled link into a trusted outbound notification channel, while other Mustache sinks remain unescaped until restart. This issue is fixed in version 8.0.3.
