YayPricing subscriber REST access permits pricing takeover
YayPricing before 3.5.7 protects several REST routes only with a shared nonce and omits capability checks. Any authenticated user, including a Subscriber who can obtain the nonce, can overwrite the store's pricing configuration and disclose private coupon codes. This unscored record received deeper review because a low-privilege account gains a store-configuration write primitive and sensitive promotion data. The CNA does not disclose the route paths, HTTP methods or request fields.

This CVE was published Aug 05, 2026 and is one of 3 known issues for this plugin.
Update, patch or deactivate.
Update YayPricing to 3.5.7 or later. Audit Subscriber accounts, pricing-rule changes and coupon access, and restore pricing configuration from a known-good source if unauthorized changes are found.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
