CVE-2026-40887

In Vendure prior to 3.6.5, public Shop API products, collections, and facets queries combine mandatory visibility guards with caller-supplied filters using the caller-controlled filterOperator. When filterOperator is OR, a predicate matching a hidden entity can bypass the Product.enabled, Collection.isPrivate, or Facet.isPrivate guard. An unauthenticated caller can therefore retrieve disabled products and private collections or facets.

Vendure prior to 3.6.5 allows an unauthenticated caller to supply a catastrophically backtracking regular expression pattern through StringOperators.regex in the public Shop GraphQL API. Deployments using better-sqlite3 and sqljs evaluate the pattern synchronously in the Node.js event loop, which can block request processing. The issue is fixed in version 3.6.5.

In Vendure, the createCustomerAndUser function in external authentication matches an existing customer by email address and attaches a new external authentication method without requiring verification. An attacker can use an unverified email to hijack the victim's account.

Vendure prior to 3.6.5 contains a stored XSS vulnerability in RichTextDescriptionCell, which assigns an administrator-controlled description to a live element's innerHTML and then reads textContent. Active resource markup can execute an event handler during the innerHTML assignment before textContent is read. A lower-privilege administrator can store such markup in descriptions rendered by the Products, Collections, Promotions, Payment Methods, or Shipping Methods lists, and script executes when another administrator views the affected row.

A vulnerability in Vendure (up to version 3.7.1) allows channel-scoped administrators to modify other tenants' data by bypassing channel isolation validation. The attack involves supplying global IDs of StockLocation or Asset entities from different channels.
