The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

n8n is a n8n Workflow Automation Tool
Affected versions of this package are vulnerable to Incorrect Authorization in the Token Exchange process. An attacker can gain elevated privileges and execute arbitrary code by obtaining a valid external JWT accepted by a configured trusted key, which allows invoking administrator-only Public API operations such as role escalation, user creation, and user deletion.
Note: This is only exploitable if both the Token Exchange feature and the Public API are enabled, and the attacker can obtain an external JWT trusted by a configured issuer. Role escalation additionally requires an Advanced Permissions license; Community Package installation additionally requires both N8N_COMMUNITY_PACKAGES_ENABLED=true and N8N_UNVERIFIED_PACKAGES_ENABLED=true.
This vulnerability can be mitigated by disabling the Token Exchange feature by setting N8N_TOKEN_EXCHANGE_ENABLED=false or N8N_ENV_FEAT_TOKEN_EXCHANGE=false, restricting Public API access at the network level to trusted clients only, or disabling unverified Community Package installation by setting N8N_UNVERIFIED_PACKAGES_ENABLED=false.
