n8n is an open source workflow automation platform. Prior to 1.123.61, 2.27.4, and, 2.28.1, an authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the $request object inside an HTTP Request node's pagination expression and exfiltrate the secret through item data. This issue is fixed in versions 1.123.61, 2.27.4, and 2.28.1.

n8n: Shared Credential Header Leak via HTTP Request Pagination Expression

CVE-2026-59209 [HIGH] CWE-200 n8n: Shared Credential Header Leak via HTTP Request Pagination Expression
n8n: Shared Credential Header Leak via HTTP Request Pagination Expression
## Impact
An authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the `$request` object inside an HTTP Request node's pagination expression. When an HTTP Header Auth credential is applied to a paginated request, the secret is present in `$request.headers` when pagination expressions are evaluated. A user-controlled expression could read that secret, copy it into item data, and exfiltrate it through a later HTTP Request node, bypassing credential domain restrictions, since the secret leaves via item data rather than the credential's own request mechanism.
This issue only affects instances with `N8N_EXPRESSION_ENGINE=vm` set, where paginated HTTP Re
