CVE-2026-45444: Critical File Upload Flaw in Gift Cards For WooCommerce Pro

CVE-2026-45444: Critical File Upload Flaw in Gift Cards For WooCommerce Pro

The National Vulnerability Database has disclosed CVE-2026-45444, a critical vulnerability impacting the Gift Cards For WooCommerce Pro plugin. This flaw, rated a perfect 10.0 CVSS, allows for unrestricted file uploads of dangerous types, specifically enabling the use of malicious files.

This vulnerability affects Gift Cards For WooCommerce Pro versions up to and including 4.2.6. The ability for an unauthenticated attacker to upload arbitrary malicious files translates directly into remote code execution (RCE). This isn’t just a defacement risk; it’s a full compromise of the underlying server.

Attackers will leverage this to establish persistent access, exfiltrate data, or pivot to other systems on the network. The low attack complexity and lack of required authentication make this an extremely attractive target for opportunistic threat actors. Defenders must treat this with the highest urgency.

What This Means For You

  • If your organization uses Gift Cards For WooCommerce Pro, check your version immediately. Any version up to 4.2.6 is vulnerable to full server compromise via unrestricted file upload. Patching this is non-negotiable and should be your top priority. Assume compromise if you were running an affected version unpatched.
