Is Premium Packages safe? Known vulnerabilities and latest version

The Premium Packages WordPress plugin before 7.2.2 does not prevent unauthenticated visitors from overwriting the stored price of items in their shopping cart, allowing them to create orders for any product at an arbitrary total of their choosing.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'note' parameter in all versions up to, and including, 7.2.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit bypasses tag-based filtering because the payload is stored as a hex-escaped sequence (e.g., \x3cimg onerror=...\x3e) that sanitize_textarea_field does not strip, and is only decoded back into a live HTML tag by stripcslashes() during admin rendering — after all sanitization has occurred.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting via 'order_email' in all versions up to, and including, 7.0.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'checkout[billing][phone] (and state / taxid / email)' parameter in all versions up to, and including, 7.2.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'cart_items[][product_name]' Parameter in all versions up to, and including, 7.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The checkout REST route uses permission_callback set to __return_true and the invoice loader performs no order ownership check, meaning an unauthenticated attacker can both persist the payload and ensure it is renderable to any logged-in user who accesses the invoice.

The Premium Packages WordPress plugin before 7.2.1 does not verify PayPal's webhook signature before processing payment and subscription notifications, allowing unauthenticated attackers to forge payment confirmations and subscription-cancellation events against any order whose transaction id they know.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in W3 Eden WPDM – Premium Packages wpdm-premium-packages allows DOM-Based XSS.This issue affects WPDM – Premium Packages: from n/a through 7.0.5.

The Premium Packages WordPress plugin before 7.0.7 does not validate a withdrawal request against the requesting user's actual earned balance, allowing any authenticated user, including a subscriber with no sales at all, to submit a payout request for an arbitrary amount, which an administrator may then approve and pay out.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to SQL Injection via the 'code' parameter of the POST /wp-json/wpdmpp/v1/cart/coupon REST API endpoint in versions up to, and including, 6.2.0. This is due to insufficient escaping on the user-supplied parameter, which is interpolated directly into a raw SQL query string in the CouponCodes::find() method without use of $wpdb->prepare() or esc_sql(). This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Unauthenticated SQL Injection in WPDM – Premium Packages <= 6.2.0 versions.

Unauthenticated Broken Access Control in WPDM – Premium Packages <= 6.2.0 versions.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to generic SQL Injection via the 'orderby' parameter in all versions up to, and including, 7.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with admin-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 7.0.4 via the `wpdmppdl` parameter. This is due to the `download()` function — hooked to the unauthenticated WordPress `wp` action — decoding the attacker-controlled `wpdmppdl` parameter using only `base64_decode()` and `json_decode()` with no HMAC, cryptographic signature, or nonce verification, and then issuing WordPress authentication cookies after a domain check that is trivially bypassed because both sides of the comparison are attacker-supplied values. This makes it possible for unauthenticated attackers to authenticate as any non-administrator WordPress user, including subscribers, customers, contributors, authors, editors, and shop managers, who owns an order, gaining full session-level access to that account.

Cross-Site Request Forgery (CSRF) vulnerability in Shahjada WPDM – Premium Packages wpdm-premium-packages allows Cross Site Request Forgery.This issue affects WPDM – Premium Packages: from n/a through <= 6.0.2.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Shahjada WPDM – Premium Packages wpdm-premium-packages allows Stored XSS.This issue affects WPDM – Premium Packages: from n/a through <= 6.0.6.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 5.9.3. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpdmpp_pay_link shortcode in all versions up to, and including, 5.9.3 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.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Shahjada WPDM – Premium Packages wpdm-premium-packages.This issue affects WPDM – Premium Packages: from n/a through <= 6.0.5.

The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.9.1. This is due to missing nonce validation on the addRefund() function. This makes it possible for unauthenticated attackers to perform actions such as initiating refunds via a forged request granted they can trick a site administrator or shop manager into performing an action such as clicking on a link.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in W3 Eden, Inc. Premium Packages allows Reflected XSS.This issue affects Premium Packages: from n/a through 5.8.2.

The Premium Packages - Sell Digital Products Securely plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.7.4 due to insufficient restriction on the 'wpdmpp_update_profile' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'profile[role]' parameter during a profile update.
