Technical description

LimeSurvey Community Edition 7.7.0 contains a stored cross-site scripting vulnerability in the Central Participants Database blocklist control. An authenticated user with only global participantpanel:import permission can import a CSV participant_id containing HTML. The import flow persists that value without model validation. When a CPDB editor opens the participant list, LimeSurvey derives ButtonGroupWidget id and name attributes from participant_id and inserts them without HTML encoding, causing attacker-controlled markup to execute in the victim's authenticated LimeSurvey origin. Exploitation can access session-exposed data and issue same-origin requests with the victim's effective permissions.

—

———The ARMember Premium – Membership Plugin, Content Restriction, Member Levels, User Profile & User signup plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Registration Custom Field (Profile Cover) in all versions up to, and including, 7.8.1 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.5h CVE-2026-849387.2 HIG

———The Avada (Fusion) Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Form Notification Dynamic-Data action_hook → Media Upload Chain (ID3 Metadata / html_attributes) in all versions up to, and including, 3.16.1 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. Exploitation requires that a Fusion Form is embedded on an admin-authored page (granting manage_options context to the Dynamic Data action hook callback), and that a Post Cards element configured to display attachment post types is present on a publicly accessible page so the planted shortcode payload is rendered.5h CVE-2026-1250823.5 LOW

———SAP NetWeaver Visual Composer does not perform sufficient input validation and output encoding on certain request data. An unauthenticated attacker could craft a malicious link containing specially crafted input. If a victim clicks the link, the injected script executes in the victim's browser within the context of the affected application. This results in a low impact on confidentiality and integrity. There is no impact on availability.11h CVE-2026-1098106.1 MED

———SAP NetWeaver Application Server Java (Web Dynpro Java) does not sufficiently validate certain request parameters used to resolve styling resources in the application. An unauthenticated attacker could craft a malicious link that, when clicked by an authenticated victim, causes the victim's browser to load attacker-controlled styling content within the trusted application context. Successful exploitation could allow the attacker to redress the trusted user interface for phishing purposes and exfiltrate limited web page content, resulting in a low impact on confidentiality and integrity. There is no impact on availability.11h CVE-2026-1253955.4 MED
