Technical description

The Page Builder: Pagelayer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Button widget's Custom Attributes field in all versions up to, and including, 2.0.8. This is due to an incomplete event handler blocklist in the 'pagelayer_xss_content' XSS filtering function, which blocks common, but not all, event handlers. 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.

——0Decidim is a participatory democracy framework. Prior to 0.32.0, a low-privilege process-scoped administrator or election editor with question-management rights can store HTML or script-bearing content in question.body. The question_title helper returns the translatable question body through html_safe without a sanitization boundary, causing stored script execution when visitors open public election pages or voting booth screens. The persisted script executes in visitors' browsers. The vulnerability is fixed in 0.32.0.21h CVE-2026-906507.2 HIG

——0The MotoPress Hotel Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Stripe Webhook event object 'id' in all versions up to, and including, 6.2.4 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 Stripe webhook listener only verifies the webhook signature when an optional Stripe signing secret has been configured; because that secret is empty by default, a forged webhook is accepted without cryptographic verification, and the attacker-controlled event object 'id' (e.g. a forged 'refund.created' refund id) is written unescaped into the payment log and later echoed unsanitized when an administrator views the payment. An attacker must know a valid Stripe PaymentIntent ID for an existing payment to route the forged webhook to a payment record. Note: The vulnerable webhook handler (webhook-listener.php) is part of the premium Stripe gateway integration and is not present in the lite plugin directory.23h CVE-2026-886186.5 MED

——0Outerbase Studio is a lightweight browser-based database GUI supporting PostgreSQL, MySQL, and SQLite. In version 0.10.2 and earlier, TextComponent in src/components/chart/index.tsx renders unsanitized Text Widget content through dangerouslySetInnerHTML, allowing injected markup with script-capable event handlers to execute when the widget is displayed. Outerbase Cloud and its backend services were discontinued in 2025, and the current architecture uses local browser dashboard storage, so the impact is limited to local self-XSS. Authentication token theft, account takeover, and backend database access are not applicable to the current architecture. No fixed release is available as of this review.22h CVE-2026-156096.4 MED
