The Customer Email Verification for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation via the algwcevverifyemail parameter in versions up to, and including, 3.3.0. The vulnerability exists because algwcevgenerateusercode() generates the per-user activation secret using wprand(100) when the plugin's 'Encoding method' is set to 'hashids', producing only ~101 possible values (~7 bits of entropy); the resulting token is a reversible Hashids encoding with no cryptographic MAC, and the unauthenticated verify() handler — hooked to init at PHPINTMAX with no nonce check and no rate limiting — accepts and acts on the attacker-controlled ?algwcevverifyemail= GET parameter directly. This makes it possible for unauthenticated attackers to gain authentication as any unverified WordPress account, including administrator-level accounts, by brute-forcing the trivially small activation code space via a forged verification URL. Exploitation requires that the 'Encoding method' setting be changed to 'hashids' (non-default), that the attacker recover or brute-force the Hashids salt (which defaults to an md5(time()) value set at first initialization), and that the target account's email address remain unverified.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WPFactory Coupons & Add to Cart by URL Links for WooCommerce url-coupons-for-woocommerce-by-algoritmika allows Stored XSS.This issue affects Coupons & Add to Cart by URL Links for WooCommerce: from n/a through <= 1.7.7.

The Cost of Goods: Product Cost & Profit Calculator for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'algwccogproductcost' and 'algwccogproductprofit' shortcodes in all versions up to, and including, 4.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
