CVE Vulnerability Catalog

Tornado before 6.5.9 fails to limit the number of query string fields in HTTPServerRequest.__init__, allowing remote attackers to cause event-loop stalling by sending requests with thousands of query parameters. Attackers can send unauthenticated GET requests with unbounded query-string field counts to degrade response times for all clients sharing the same IOLoop.

n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an approval bypass vulnerability in the Send and Wait node's Approve Within Chat mode. Attackers can submit resume requests without verification of the requester's identity or approval permissions, allowing unauthenticated users to advance waiting executions and trigger guarded actions.

n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an unescaped parameter interpolation vulnerability in SendGrid, Freshservice, and ServiceNow nodes that allows attackers to bypass filters by breaking out of query literals. Attackers can exploit this by binding vulnerable node parameters to untrusted external input to widen single-record lookups into match-all queries, exposing bulk data including contact lists, tickets, and directory entries.

n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain a path traversal vulnerability in signed resume URL generation for Send-and-Wait approvals. Attackers with workflow creation permissions can mint valid approval URLs for gates in projects they cannot access by exploiting unresolved traversal sequences in caller-controlled node IDs, enabling cross-project approval forgery.

n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 fail to verify the x-webflow-signature HMAC in the Webflow Trigger node webhook handler. Unauthenticated attackers can send forged webhook requests with attacker-controlled payloads to trigger workflows and manipulate downstream actions like record creation or API calls.

The Gutenberg Essential Blocks – Page Builder for Gutenberg Blocks & Patterns plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Google Map block's 'marker' attribute in versions up to, and including, 6.4.5. This is due to insufficient input sanitization and output escaping on marker title/content values, which are stored as JSON and then decoded and concatenated directly into raw HTML by the frontend script's InfoWindow content builder. 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.

A flaw was found in oauth-proxy. The application fails to properly validate the destination redirect parameter (`rd`) during post-login redirection. A remote attacker can exploit this vulnerability by enticing a user to follow a specially crafted link, resulting in the user being redirected to an arbitrary external website after authenticating. This open redirect can be leveraged to conduct phishing attacks or credential theft.

CVE-2026-7176: the Help text and Title parameters in the endpoint /events/<event_name>-<event_city>/custom_form/edit during the process of creating or modifying forms associated with ticket sales for an event, which allows for the injection of JavaScript that will execute on the public ticket purchase page for the event.

CVE-2026-7175: the Business Name parameter in the /promoters/edit endpoint of the My Profile section of a promoter’s profile, which allows the injection of JavaScript code that will execute on the promoter’s public page.

CVE-2026-7174: Stored Cross-Site Scripting vulnerability in Entradium, by Crocantickets. Specifically, in the Name and Field parameters of the endpoint /tools/discount_wizard/discount_config during the process of creating discounts assigned to an event. This vulnerability allows JavaScript code to be injected into the affected parameters, which executes when an event’s discount list page is displayed. Successful exploitation of this vulnerability could allow a remote attacker to send a specially crafted URL to the victim and steal their session data.

CVE-2026-7173: Cross-Site Scripting vulnerability in Entradium, by Crocantickets. Exploitation of this vulnerability could allow a remote attacker to send a specially crafted URL to the victim and steal their session data. (Stored XSS) The City parameter in the endpoint /events/<event_name>/edit_general during the process of creating or editing events assigned to a promoter allows for the injection of JavaScript that will execute on the event’s public page. (Reflected XSS) The Description parameter in the endpoint /events/<event_name>/edit-general when attempting to create or modify an event without filling in all required fields.

CSRF vulnerability allows unauthorized deletion of alert commands via sequential, unvalidated GET requests when an authenticated administrator visits a malicious page. Affects Pandora FMS from version 777 onwards.

CSRF vulnerability allows unauthorized deletion of event responses via a forged GET request when an authenticated administrator visits a malicious page. Affects Pandora FMS from version 777 onwards.

In JetBrains YouTrack before 2026.2.19422, SSRF was possible via the GitHub VCS integration.

In JetBrains YouTrack before 2026.2.19422, iDOR in inbox threads allowed reading other users' notifications.

In JetBrains YouTrack before 2026.2.19422, missing authorisation allowed reloading of translation catalogs.

In JetBrains YouTrack before 2026.2.19422, privilege escalation was possible via user group membership changes.

In JetBrains YouTrack before 2026.2.19422, DoS attack was possible via crafted PSD attachments.

In JetBrains YouTrack before 2026.2.19422, iDOR in the issue activities API allowed reading restricted issues.

The Awesome Support – WordPress HelpDesk & Support Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'gdpr-data' parameter in all versions up to, and including, 6.4.0 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. This is exploitable by Subscriber-level users against other accounts because the AJAX handlers accept an arbitrary gdpr-user ID without verifying it belongs to the requester, and the required wpas-gdpr-nonce is emitted via wp_localize_script to every logged-in user on frontend plugin pages and on /wp-admin/profile.php.
