CVE-2025-58442: Saleor

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

Saleor is an e-commerce platform. Starting in version 3.21.0 and prior to version 3.21.16, requesting certain fields in the response of `accountRegister` may result in errors that could unintentionally reveal whether a user with the provided email already exists in Saleor. Version 3.21.16 fixes the issue. As a workaround, rate-limit the mutation to reduce the impact.

Affected products

• Saleor Saleor: from 3.21.0, before 3.21.16 (fixed in 3.21.16)
