CVE-2026-84099: CWE-502 Deserialization of Untrusted Data in wpstorecart
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.
AI Analysis
Technical Summary
CVE-2026-84099 describes a deserialization of untrusted data vulnerability (CWE-502) in the wpstorecart WordPress plugin versions up to and including 5.0.7. The vulnerability arises from direct, unauthenticated access to a bundled add-on that deserializes user input without class restrictions, enabling attackers to inject arbitrary PHP objects. This flaw can potentially be escalated if the target site contains appropriate gadget chains for code execution.
Potential Impact
Unauthenticated attackers can inject arbitrary PHP objects via deserialization, which may lead to remote code execution or other escalated impacts if the site has exploitable gadget chains. The vulnerability affects the confidentiality, integrity, and availability of the affected WordPress site.
Mitigation Recommendations
No official patch or remediation details are provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the vulnerable add-on if possible and monitor for suspicious activity related to deserialization attempts.
