CVE-2026-34770

Wikipedia 12.0 contains a denial of service vulnerability that allows unauthenticated attackers to crash the application by submitting oversized input through the search functionality. Attackers can paste a large buffer of repeated characters into the search bar to trigger an application crash.

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The is_chunked_transfer() function uses strcmp() to compare the header value against "chunked", even though RFC 7230 specifies that transfer-coding names are case-insensitive. By sending a request with Transfer-Encoding: Chunked, an unauthenticated remote attacker can cause Tinyproxy to misinterpret the request as having no body. In this state, Tinyproxy sets content_length.client to -1, skips pull_client_data_chunked(), forwards request headers upstream, and transitions into relay_connection() raw TCP forwarding while unread body data remains buffered. This leads to inconsistent request state between Tinyproxy and backend servers. RFC-compliant backends (e.g., Node.js, Nginx) will continue waiting for chunked body data, causing connections to hang indefinitely. This behavior enables application-level denial of service through backend worker exhaustion. Additionally, in deployments where Tinyproxy is used for request-body inspection, filtering, or security enforcement, the unread body may be forwarded without proper inspection, resulting in potential security control bypass.

A security flaw has been discovered in Tenda 4G03 Pro up to 1.0/1.1/04.03.01.53/192.168.0.1. Affected by this vulnerability is an unknown functionality of the file /bin/httpd. The manipulation results in improper access controls. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.

Dolibarr ERP/CRM versions prior to 23.0.2 contain an authenticated remote code execution vulnerability in the dol_eval_standard() function that fails to apply forbidden string checks in whitelist mode and does not detect PHP dynamic callable syntax. Attackers with administrator privileges can inject malicious payloads through computed extrafields or other evaluation paths using PHP dynamic callable syntax to bypass validation and achieve arbitrary command execution via eval().

MCPHub in versions below 0.11.0 is vulnerable to authentication bypass. Some endpoints are not protected by authentication middleware, allowing an unauthenticated attacker to perform actions in the name of other users and using their privileges.

The Eventin – Events Calendar, Event Booking, Ticket & Registration (AI Powered) plugin for WordPress is vulnerable to unauthorized access of data due to a improper capability check on the get_item_permissions_check() function in all versions up to, and including, 4.1.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary order data including customer PII (name, email, phone) by iterating order IDs.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache PDFBox Examples. This issue affects the ExtractEmbeddedFiles example in Apache PDFBox: from 2.0.24 through 2.0.36, from 3.0.0 through 3.0.7. Users are recommended to update to version 2.0.37 or 3.0.8 once available. Until then, they should apply the fix provided in GitHub PR 427. The ExtractEmbeddedFiles example contained a path traversal vulnerability (CWE-22) mentioned in CVE-2026-23907. However the change in the releases 2.0.36 and 3.0.7 is flawed because it doesn't consider the file path separator. Because of that, a user having writing rights on /home/ABC could be victim to a malicious PDF resulting in a write attempt to any path starting with /home/ABC, e.g. "/home/ABCDEF". Users who have copied this example into their production code should apply the mentioned change. The example has been changed accordingly and is available in the project repository.

A vulnerability has been identified in Industrial Edge Management Pro V1 (All versions >= V1.7.6 < V1.15.17), Industrial Edge Management Pro V2 (All versions >= V2.0.0 < V2.1.1), Industrial Edge Management Virtual (All versions >= V2.2.0 < V2.8.0). Affected management systems do not properly enforce user authentication on remote connections to devices. This could facilitate an unauthenticated remote attacker to circumvent authentication and impersonate a legitimate user. Successful exploitation requires that the attacker has identified the header and port used for remote connections to devices and that the remote connection feature is enabled for the device. Exploitation allows the attacker to tunnel to the device. Security features on this device itself (e.g. app specific authentication) are not affected.

Nodcms contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized administrative actions by crafting malicious forms. Attackers can trick authenticated administrators into submitting requests to admin/user_manipulate and admin/settings/generall endpoints to create users or modify application settings without explicit consent.
