The Quick PayPal Payments: Payment Button & Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form' parameter in all versions up to, and including, 6.0.4 due to insufficient input sanitization and output escaping. 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. Because wp_kses_post strips only HTML tags, a quote-breaking payload containing no angle brackets survives post save intact, and the injected script fires for every viewer of the post — including higher-privileged Editors and Administrators who routinely preview a Contributor's pending content.

Sep 25, 2026Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more: Privilege EscalationCVE-2026-89426 · WordPress plugins & themes · reported by WordfenceHigh 8.8
The Knit Pay – Cashfree, Instamojo, Razorpay, PayPal and more plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 9.6.1.0. This is due to the `maybe_update_user_role()` function reading the target role directly from an attacker-controlled Gravity Forms entry field — configured via the feed's `user_role_field_id` — and passing it to `WP_User::set_role()` without validating the supplied value against an allowlist of permitted roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to administrator by tampering with the hidden role field value at form submission time. Exploitation is further enabled by the fact that $0 orders are synchronously marked as SUCCESS during form submission without requiring a real payment, and when no GF User Registration user can be resolved, the role assignment target falls back to `$lead['created_by']` — the currently authenticated submitter's own user ID — making any authenticated form submitter an eligible exploitation target.

Joomla Extension - j2commerce.com - Unescaped request data reflected into PayPal notify redirect in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - A crafted link to the paypal notify endpoint, if followed by a victim's browser (or an automated system that fetches it), causes the resulting redirect to `com_j2store`'s checkout controller to carry attacker-chosen query parameters instead of only the intended `view=checkout&task=confirmPayment&orderpayment_type=...&paction=process` set — parameter injection/smuggling into that follow-up request. This requires a victim to load the crafted link (`UI:R`/`UI:P`); it does not by itself grant an unauthenticated attacker anything they could not already obtain by requesting the target `com_j2store` URL directly with their own parameters.

Joomla Extension - j2commerce.com - Unauthenticated PayPal callback forgery leading to order confirmation fraud in J2Store 1.0.0-3.3.21, 4.0.0-4.0.21, 4.1.0-4.1.6 - The PayPal IPN listener's signature check (`_validateIPN()`) accepted `UNVERIFIED` and any non-`INVALID` response as valid, made its verification request with `CURLOPT_SSL_VERIFYPEER` disabled, and stored its verdict in a field nothing downstream ever checked — so processing continued regardless of the outcome. Separately, the paid-amount comparison only ran when `mc_gross` was a positive number; omitting the field from the POST body (`floatval(null) == 0`) skipped the check entirely. Combined with a merchant-configured `receiver_email` and a sequential, enumerable order id read from the `custom` field, an anonymous POST was enough to move a pending order straight to `CONFIRMED` with no payment, or force another customer's pending order to `FAILED`. `paypalv2.php` performed no amount check under any circumstances.

Aug 1, 2026WooCommerce PayPal Payments: Sensitive Information DisclosureCVE-2025-14073 · WordPress plugins & themes · reported by WordfenceMedium 5.3
The WooCommerce PayPal Payments plugin for WordPress is vulnerable to Sensitive Information Disclosure due to an Insecure Direct Object Reference in all versions up to, and including, 3.3.2 via the `enqueue_paypal_insights_script_on_order_received()` function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to obtain sensitive order information including order keys, which can then be leveraged to access full customer billing details (name, email, phone, address) via the WooCommerce Store API within a 10-minute grace period after order creation.

Jun 17, 2026Contest Gallery – Upload & Vote Photos, Media, Sell with PayPal & Stripe: Privilege EscalationCVE-2026-12165 · WordPress plugins & themes · reported by WordfenceHigh 8.8
The Contest Gallery – Upload & Vote Photos, Media, Sell with PayPal & Stripe plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 30.0.2 via the `RegistryUserRole` parameter. This is due to the plugin's admin menu being registered at the `edit_posts` capability level — granting Contributor-level users access to the plugin's admin pages and a valid `cg_admin` nonce — while the option-saving handler in `change-options-and-sizes.php` performs no `current_user_can()` capability check beyond `check_admin_referer('cg_admin')`, and the `RegistryUserRole` value is processed only through `sanitize_text_field()` and `htmlentities()` without restriction to an allowlist of permitted role names. This makes it possible for authenticated attackers, with author-level access and above, to overwrite the plugin's stored `RegistryUserRole` option with `administrator`, which the `cg_create_wp_user_from_google_user` function then reads back from the `contest_gal1ery_registry_and_login_options` database table without any allowlist validation and passes directly to `wp_update_user()`, effectively promoting a newly registered Google sign-in account to Administrat

May 29, 2026Contact Form 7 – PayPal & Stripe Add-on: Payment BypassCVE-2026-9189 · WordPress plugins & themes · reported by WordfenceMedium 5.3
The Contact Form 7 – PayPal & Stripe Add-on plugin for WordPress is vulnerable to Payment Bypass via Insufficient Verification of Data Authenticity in all versions up to, and including, 2.4.9. Although `cf7pp_paypal_ipn_handler()` correctly validates IPN authenticity by posting back to PayPal with `cmd=_notify-validate`, it fails to compare the IPN payload's `mc_gross` (payment amount), `mc_currency`, or `receiver_email` fields against the corresponding stored order values before passing the attacker-controlled `invoice` field directly to `cf7pp_complete_payment()`, which marks the order completed after only an integer cast with no amount verification. This makes it possible for unauthenticated attackers to mark arbitrary high-value pending orders as fully paid by making a minimal real PayPal payment and crafting an IPN whose `invoice` parameter references the targeted order, effectively completing purchases without tendering the required payment amount.
