Answer in brief
CVE-2026-77075 records a High severity (CVSS 8.4) vulnerability in n8n before 1.123.69 Expression Injection via Resource Locator. The current sources do not mark it as known exploited. The current feed maps n8n-io/n8n (generic), n8n-io/n8n (generic), n8n-io/n8n (generic), n8n-io/n8n (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

n8n before 1.123.69, 2.x before 2.33.4, and 2.34.x before 2.34.1 contain an expression injection vulnerability in resource-locator field link preview rendering. The editor spliced the field's stored value directly into the node type's URL template without checking for expression syntax. An authenticated member can store a malicious value so that when another user opens the affected node in the editor, the injected expression is evaluated as JavaScript in the victim's authenticated session (cross-user script execution).
