CVE-2026-14182

This CVE represents a type-coercion authentication bypass in a WooCommerce plugin's email verification flow. The vulnerability allows an attacker to bypass email verification by supplying a value that PHP's loose comparison operator (==) coerces to match the expected verification token — for example, a numeric string that PHP interprets as equivalent to a numeric token, or an array that stringifies to the expected value. The attack is pre-authentication, meaning any unverified user account can be hijacked without prior access. The CVSS 9.8 score reflects the attack surface (unverified users on a payment-adjacent platform) rather than exploit complexity. In practice, exploiting this requires understanding how PHP's type coercion evaluates to true under == comparison — specifically, that '0e123456' == '0e789012' evaluates as true because both are interpreted as scientific notation floats equal to zero, or that array('value') == 'value' returns true after stringification. This is not a subtle bug; it is the predictable output of using loose comparison on user-derived values without awareness of PHP's type coercion rules. What should you do? First, confirm whether your WooCommerce installation runs any plugin that handles email verification — this is common in registration, password reset, and order confirmation flows. Second, check the plugin's codebase for any == comparisons on variables containing verification codes, confirmation tokens, or security hashes that originate from user input. If you find == in authentication-adjacent logic, flag it for immediate review. Third, if you maintain or develop WordPress plugins, integrate a static analysis tool (PHPStan with strict type rules, Psalm, or phpcs-security-audit) into your CI pipeline and configure it to treat any loose comparison in auth code as a build failure. The deeper problem is that the WordPress plugin ecosystem has no institutionalized guardrail for this class of bug. The same loose-comparison authentication bypass pattern has been CVE'd repeatedly since 2010 (phpBB, WordPress core, and now WooCommerce plugins). Each instance gets patched in isolation, but no structural intervention prevents the next one. The tooling to catch this exists — PHPStan and Psalm have flagged loose comparisons on security paths for years — but it has never achieved meaningful penetration in the WordPress plugin development environment, where developers often work without dedicated security tooling on small teams with thin margins. This is not a story about careless developers; it is about an ecosystem that has not built the friction needed to catch a known, recurring vulnerability class before deployment.
