CVE-2026-88904: Unknown Puppyfw

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The PuppyFW WordPress plugin through 0.4.4 does not have proper authorisation on one of its REST routes, which tests the caller against a capability taken from the request itself, allowing any authenticated user, including subscribers, to add, modify and delete arbitrary blog options and thereby escalate their privileges.

Affected products

• Unknown Puppyfw: up to and including 0.4.4
