Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.1.0 until 6.4.41, 7.4.13, and 8.0.13, UrlAttributeSanitizer::getSupportedAttributes() omitted URL-bearing attributes on <object>, <applet>, <iframe>, and <img>, and <meta http-equiv="refresh"> URLs inside content bypassed URL sanitization, allowing explicitly enabled elements or attributes to pass javascript: and similar payloads into sanitized output. This issue is fixed in versions 6.4.41, 7.4.13, and 8.0.13.

———Decidim 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 0.32.0.3h CVE-2026-918362.8 BAJ

———A flaw has been found in OpenClaw ClawScan up to 0.1.6. This affects an unknown function of the file internal/runner/static_scanner.go of the component Static Scanner. This manipulation causes incomplete comparison with missing factors. It is possible to launch the attack on the local host. The exploit has been published and may be used. Upgrading to version 0.1.7 mitigates this issue. Patch name: 9f6a6fbb9f1137345566d0ab44c73893dfe112fa. The affected component should be upgraded.5h CVE-2026-906507.2 ALT

———The 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.5h CVE-2026-556504.4 MED

———Outerbase 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.4h CVE-2026-156096.4 MED

——0Steedos Platform through 3.0.15-beta.47 contains a reflected cross-site scripting vulnerability in the anonymous /api/page/render endpoint that fails to properly escape query parameters in inline script elements.
