CVE-2026-77075 [HIGH] – n8n before 1.123.69, 2.x before 2.33.4, and 2.34.x before 2.34.1 contain an expression inj

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).
