CVE-2026-11575: PhonePe Payment Solutions < 3.1.0 - Unauthenticated Payment Bypass via Forged Callback
- Severity: high (CVSS 7.5 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-07-17 · updated 2026-07-17
- Weakness: CWE-862
Description
The PhonePe Payment Solutions WordPress plugin before 3.1.0 does not properly verify the authenticity of incoming payment callbacks: the secret used to validate the callback signature is empty on sites configured through the current setup flow, so the expected signature reduces to an unkeyed hash of the request body that anyone can compute. This allows unauthenticated attackers to forge a payment-success notification and mark unpaid WooCommerce orders as paid without any payment being made.
