    CVE-2026-63466 (GCVE-0-2026-63466)

    Vulnerability from nvd – Published: 2026-08-21 18:21 – Updated: 2026-08-21 21:43

    Title
    Unleash: Global Mustache.escape override disables HTML escaping process-wide, enabling Slack/Teams link-injection via unrestricted username
    Summary
    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.

    Title
    Unleash: Unauthenticated single-request DoS via OpenAPI validation error formatter
    Summary
    Unleash is an open-source feature management platform. Prior to 7.5.2, 7.6.5, and 8.0.2, the shared OpenAPI validation error path in src/lib/error/bad-data-error.ts passes a raw request value from lodash.get to JSON.stringify in genericErrorMessage and fromOpenApiValidationErrors without guarding stack exhaustion. An unauthenticated attacker can send a roughly 10 KB JSON value nested thousands of levels deep to POST /edge/validate, POST /edge/issue-token, or another OpenAPI-validated endpoint, causing RangeError: Maximum call stack size exceeded in openAPIValidationMiddleware and terminating the Node process because no uncaughtException handler recovers it. Replaying the request can sustain a complete service outage. This issue is fixed in versions 7.5.2, 7.6.5, and 8.0.2.

    CVE-2026-63004 (GCVE-0-2026-63004)

    Vulnerability from nvd – Published: 2026-08-21 18:05 – Updated: 2026-08-21 19:22

    Title
    Unleash: Addon webhook URL is dialed server-side with no internal-address filtering, enabling SSRF to internal services / cloud metadata and exfiltration of configured request headers
    Summary
    Unleash is an open-source feature management platform. Prior to 7.5.2, 7.6.5, and 8.0.2, the addon and integration subsystem passes the operator-controlled parameters.url value from src/lib/addons/webhook.ts and the Slack, Microsoft Teams, Datadog, and New Relic integrations to Addon.fetchRetry in src/lib/addons/addon.ts without restricting loopback, link-local, private, or cloud metadata addresses. An authenticated actor with the root CREATE_ADDON or UPDATE_ADDON permission can cause the server to send requests from inside its network boundary, use integration event status as a blind probing oracle, forward Authorization, customHeaders, or DD-API-KEY values to an attacker-observed host, and deliver the feature-event JSON body to internal services. This issue is fixed in versions 7.5.2, 7.6.5, and 8.0.2.

    Title
    Unleash: Global Mustache.escape override disables HTML escaping process-wide, enabling Slack/Teams link-injection via unrestricted username
    Summary
    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.

    Title
    Unleash: Unauthenticated single-request DoS via OpenAPI validation error formatter
    Summary
    Unleash is an open-source feature management platform. Prior to 7.5.2, 7.6.5, and 8.0.2, the shared OpenAPI validation error path in src/lib/error/bad-data-error.ts passes a raw request value from lodash.get to JSON.stringify in genericErrorMessage and fromOpenApiValidationErrors without guarding stack exhaustion. An unauthenticated attacker can send a roughly 10 KB JSON value nested thousands of levels deep to POST /edge/validate, POST /edge/issue-token, or another OpenAPI-validated endpoint, causing RangeError: Maximum call stack size exceeded in openAPIValidationMiddleware and terminating the Node process because no uncaughtException handler recovers it. Replaying the request can sustain a complete service outage. This issue is fixed in versions 7.5.2, 7.6.5, and 8.0.2.

    Title
    Unleash: Addon webhook URL is dialed server-side with no internal-address filtering, enabling SSRF to internal services / cloud metadata and exfiltration of configured request headers
    Summary
    Unleash is an open-source feature management platform. Prior to 7.5.2, 7.6.5, and 8.0.2, the addon and integration subsystem passes the operator-controlled parameters.url value from src/lib/addons/webhook.ts and the Slack, Microsoft Teams, Datadog, and New Relic integrations to Addon.fetchRetry in src/lib/addons/addon.ts without restricting loopback, link-local, private, or cloud metadata addresses. An authenticated actor with the root CREATE_ADDON or UPDATE_ADDON permission can cause the server to send requests from inside its network boundary, use integration event status as a blind probing oracle, forward Authorization, customHeaders, or DD-API-KEY values to an attacker-observed host, and deliver the feature-event JSON body to internal services. This issue is fixed in versions 7.5.2, 7.6.5, and 8.0.2.
