OPNsense: Stored XSS in Firewall Rules/NAT pages via a HTML-attribute breakout

OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.11, Firewall Rules and NAT views place stored category names and alias descriptions into HTML title attributes in filter_rule.volt and nat_rule.volt without quote-safe encoding. The response layer uses ENT_NOQUOTES, so a double quote survives and closes the attribute, allowing an event-handler attribute to be added to the existing span. A user with Firewall Categories or Firewall Alias Edit privileges can store a category name or alias description; the category must be assigned to a filter or NAT rule, or the alias must be referenced by a rule source or destination, and the rule must be saved so the affected tooltip is rendered. Script then executes in the session of an administrator or other user who opens the affected Rules or NAT page. The script can access CSRF material and perform authenticated actions as the victim. This issue is fixed in version 26.1.11.

OPNsense: Stored XSS to root RCE via OpenVPN client common_name in status views

OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.11, the OpenVPN connection-status dashboard widget in src/opnsense/www/js/widgets/OpenVPNClients.js and the connection-status view place a client common_name into data-common-name attributes without quote-safe encoding. Exploitation requires an OpenVPN server configured with username-as-common-name and RADIUS or LDAP authentication, plus the ability to provision or self-register a valid backend username containing a double quote; deployments where the same administrator controls both the identity backend and firewall do not cross a separate trust boundary. An authenticated client using that username can close the attribute and add an event handler, while the local user database is not affected because its username validator rejects quotes. Script executes in an administrator's session when the administrator opens the dashboard or connection-status page and the injected event is triggered; the demonstrated payload used pointer movement over the client row rather than unconditional page-load execution. The advisory demonstrates that the script can read config.xml, invoke privileged APIs, reset the root password, and obtain root command execution. This issue is fixed in version 26.1.11.

CVE-2026-59994 Medium · 4.3 CWE-79 Oct 15, 2026

EspoCRM: Pre-authentication stored HTML injection in stream notification emails about email received

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, an unauthenticated remote attacker can send an email to a monitored group or IMAP address, including an email-to-Case address, and place arbitrary HTML in its plain-text body. EspoCRM stores that body and renders it without escaping in Email Received stream notification emails sent to users following the related record, allowing HTML injection and, in mail clients that execute it, JavaScript execution. Earlier sanitization for Post and Mention notifications did not cover this notification path. This issue is fixed in version 9.3.9.

CVE-2026-55184 Low · 3.5 CWE-79 Oct 15, 2026

EspoCRM: Stored XSS in wysiwyg template fields if CSP is disabled

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, a user with Email Template or PDF Template edit permission can store crafted HTML that bypasses moderateSanitizeHtml(). When another user opens the template in edit mode and clientCspDisabled is true, the stored payload executes and can hijack the user's session. This issue is fixed in version 9.3.9.

CVE-2026-53575 Low · 2.7 CWE-79 Oct 15, 2026

EspoCRM: Persistent XSS via CSP nonce injection in applicationName setting by admin user

EspoCRM is an open source customer relationship management application. Prior to 9.3.9, an authenticated administrator can place crafted content in the applicationName setting through CSP nonce injection. The persistent injection is inserted into the main application page without escaping, allowing attacker-controlled JavaScript to run in users' sessions and leak page data, including unsaved user input. This issue is fixed in version 9.3.9.

Cross-site Scripting (XSS) in Kendo UI for jQuery Calendar and MultiViewCalendar

In Progress® Kendo® UI for jQuery prior to version 2026.3.1015, the Calendar and MultiViewCalendar month content templates render data.url and data.title without proper URL sanitization and HTML attribute encoding.

CVE-2026-106150 Medium · 5.4 CWE-79 Oct 15, 2026

Cross-site Scripting (XSS) in Kendo UI for jQuery Splitter, Window, and Tooltip

In Progress® Kendo® UI for jQuery prior to 2026.3.1015, the Splitter and Window components starting with version 2011.2.804 and the Tooltip component starting with version 2013.1.319 construct iframe markup without properly sanitizing URL values or encoding the Window iframe title. An attacker with low privileges who can control these values can inject HTML attributes, including JavaScript event handlers, through an apostrophe in an iframe URL or a crafted title. When a user interacts with the affected component, injected JavaScript can execute in the user's browser context, compromising the confidentiality and integrity of accessible data.
