—

———The Paystack WooCommerce Payment Gateway plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.8.5 via the 'key' parameter. This makes it possible for unauthenticated attackers to extract customer PII — including billing name, email address, phone number, billing address, shipping address, and purchased product list — embedded into page HTML via wp_localize_script by enumerating sequential order IDs. This is only exploitable when the merchant has enabled the optional custom metadata feature in the Paystack gateway settings.3h CVE-2026-1188014.3 MED

———The aBlocks – Gutenberg Blocks, User Dashboard Builder, Popup Builder, Form Builder & Animation Builder plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.18.0 via the 'id' parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the full rendered body content of any password-protected post of any post type by embedding the shortcode with the target post's ID. Author-level attackers and above can additionally publish a post embedding the shortcode, exposing the password-protected content to unauthenticated visitors.3h CVE-2026-172315.8 MED

———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain sensitive information due to an observable response discrepancy.4h CVE-2026-171444.3 MED

———The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 13.2.2 via the 'img (or any key the publisher references in {{GET:key}})' parameter. This makes it possible for unauthenticated attackers to extract authenticated users' HttpOnly WordPress session cookies, specifically wordpress_logged_in_* tokens, by injecting a nested {{COOKIE:}} placeholder via a GET parameter that causes the victim's browser to transmit the cookie value to an attacker-controlled host as an image src URL. Exploitation requires that a site publisher has configured a public GreenShift Element image block whose src attribute contains a {{GET:}} placeholder, and that a logged-in user can be induced to open the attacker's crafted link — neither condition is part of the plugin's default state.7h CVE-2026-1237874.3 MED
