Descrição técnica

Helium is a free online student planner for classes, homework, grades, and notes. Prior to 2.2.60, the POST /planner/attachments/ endpoint allows authenticated users to upload SVG and HTML attachments because conf/configs/common.py omits those formats from BLOCKED_ATTACHMENT_EXTENSIONS and BLOCKED_ATTACHMENT_MIME_TYPES, and helium/planner/serializers/attachmentserializer.py relies on those blocklists. An uploaded SVG served as image/svg+xml can execute embedded script when a visitor opens its public attachment URL, allowing persistent attacker-controlled active content and phishing under an application-managed storage URL. The attachment storage uses a separate origin from the application, so same-origin policy prevents the script from reading application cookies or storage, and application-session compromise is not supported by the maintained deployment configuration. This issue is fixed in version 2.2.60.

———The AgenWebsite Shipping – Plugin Ongkos Kirim & Generate Resi Otomatis Semua Kurir Indonesia plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'zipcode' parameter in all versions up to, and including, 9.2.41 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.3h CVE-2026-1205377.2 ALT

———The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'seopress_google_analytics_affiliate_tracking' and 'seopress_google_analytics_download_tracking' settings in versions up to, and including, 10.3. This is due to insufficient input sanitization and output escaping on these settings as they are interpolated into the inline Google Analytics tracking snippet by seopress_google_analytics_js(): the affiliate value receives no sanitization at all (it is omitted from inc/admin/sanitize/Sanitize.php) and lands inside a <script> block, while the download value is only passed through sanitize_text_field() and lands inside a JavaScript regular-expression literal that preserves parentheses, semicolons and slashes. This makes it possible for authenticated attackers, with Subscriber-level access and above (where an administrator has delegated the SEOPress 'analytics' capability under Settings > Advanced > Security — the precondition Wordfence accepted for CVE-2026-101357), to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.3h CVE-2026-1204796.4 MÉD

———The WP Data Access – App Builder for Tables, Forms, Dashboards, Charts & Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Data Projects front-end simple form in versions up to, and including, 5.5.90 This is due to insufficient input sanitization and output escaping on the value of TEXT/TINYTEXT/MEDIUMTEXT/LONGTEXT columns rendered by the WPDA_Simple_Form_Item_Textarea::show_item() method, which emits the stored column value directly inside a <textarea> element after only replacing '&' with '&'. 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.3h CVE-2026-1188006.4 MÉD

———The WP Data Access – App Builder for Tables, Forms, Dashboards, Charts & Maps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ImageURL column value (populated from wp_usermeta.description in the demonstrated path)' parameter in all versions up to, and including, 5.5.89 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. Exploitation requires an administrator to have published a DataTables shortcode over a database column the attacker controls (e.g., wp_usermeta.description) with the Image URL media type assigned to that column — both are supported plugin features but are not enabled by default.3h
