CVE-2026-68500: Sylius Mollie Plugin: Payment status forgery via the payment webhook

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.7% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-30 · updated 2026-10-23
• Weakness: CWE-639

Description

Sylius Mollie Plugin provides Mollie payment integration for Sylius applications. Prior to 2.2.8, 3.2.4, and 3.3.1, Sylius Mollie Plugin's POST /{_locale}/update-payment payment webhook accepts attacker-controlled id and orderId parameters but does not verify that the Mollie payment belongs to the referenced Sylius order, allowing an unauthenticated attacker with any valid paid Mollie payment ID to mark a victim order as paid without transferring funds for that order. This issue is fixed in 2.2.8, 3.2.4, and 3.3.1.

Affected products

• Sylius MolliePlugin: before 2.2.8; from 3.0.0, < 3.2.4; from 3.3.0, < 3.3.1
