wpstorecart exposes unauthenticated PHP object injection
wpstorecart through 5.0.7 allows direct unauthenticated access to a bundled add-on that deserializes caller-controlled input without restricting permitted classes. An attacker can inject arbitrary PHP objects and may escalate the primitive when a suitable gadget chain exists on the site. The authoritative export does not identify the add-on path, parameter, deserialization function, or a confirmed gadget chain.

This CVE was published Sep 12, 2026 and is one of 2 known issues for this plugin.
Update, patch or deactivate.
No fixed release is confirmed in the authoritative export. Block direct access to the bundled add-on or deactivate the plugin. The application-level fix must remove untrusted PHP deserialization, use a non-object data format, and require authenticated, authorized access to the operation.
No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.
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.
Technical description
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.
