Wine House
Monthly
Unauthenticated PHP Object Injection in the Wine House WordPress theme (version 3.20 and earlier, distributed by ThemeREX) allows a remote attacker to deliver a crafted serialized payload to an unserialize() call, which the assessed CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) rates at 9.8 Critical with full Confidentiality, Integrity, and Availability impact. Because PR:N and UI:N are confirmed by the vector, no authentication or victim interaction is required - any unauthenticated request to the affected endpoint against a site with the theme installed and active can carry the payload. No public exploit code or confirmed active exploitation was identified at time of analysis, and the practical severity is bounded by whether a usable POP gadget chain exists in the theme, WordPress core, or co-installed plugins; absent such a gadget, impact may degrade to denial of service or be non-exploitable, and the target population is limited to sites running this single commercial theme.
