HighCVSS 8.8
Published: Updated: Translated: NVD NIST

Exploitation Probability (EPSS)

Low risk
0.23%

14th percentile - higher than 14% of all known CVEs

Summary

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. This allows any authenticated user, including subscribers, to add, modify and delete arbitrary blog options and thereby escalate their privileges.

Risk Assessment

Authenticated low-privilege users can modify critical WordPress options, leading to privilege escalation and potential site takeover. This may compromise confidentiality, integrity, and availability.

Recommendation

Update the PuppyFW plugin to a version later than 0.4.4. Ensure REST routes have proper capability checks based on fixed roles, not request-supplied data.
