CVE-2026-84099
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk19th percentile - higher than 19% of all known CVEs
Summary
The wpstorecart WordPress plugin through 5.0.7 does not prevent direct, unauthenticated access to a bundled add-on that deserializes user-supplied input without restricting the permitted classes, allowing unauthenticated attackers to inject arbitrary PHP objects, which may be escalated further when a suitable gadget chain is present on the site.
Risk Assessment
An unauthenticated attacker can inject PHP objects and, with an available gadget chain, achieve remote code execution or other severe impact.
Recommendation
Update the wpstorecart plugin to a version later than 5.0.7 or remove it. Check the site for vulnerable libraries that could serve as a gadget chain.
