CVE-2023-45935
LowSummary
W wersjach Qt 6 do 6.6 odkryto problem z dereferencją wskaźnika NULL w funkcji QXcbConnection::initializeAllAtoms(). Istnieją kontrowersje dotyczące tego, ponieważ nie oczekuje się, że aplikacja X powinna kontynuować działanie w przypadku nieprzewidzianego zachowania serwera X.
Risk Assessment
Ryzyko dla organizacji polega na tym, że aplikacje mogą ulegać awariom w wyniku nieprawidłowego działania, co może prowadzić do utraty dostępności usług. Potencjalne anomalie w działaniu aplikacji mogą wpływać na stabilność systemów korzystających z Qt.
Recommendation
Zaleca się aktualizację do najnowszej wersji Qt, aby zminimalizować ryzyko związane z tą podatnością. Należy również monitorować zachowanie aplikacji w środowisku produkcyjnym.

The s2Member plugin for WordPress in versions up to and including 260927 is vulnerable to Remote Code Execution via the 'item_name' parameter. Insufficient sanitization in strip_php_tags_deep() only strips literal '<?' sequences, and a post-interpolation placeholder cleanup reassembles a valid '<?php' opener after the attacker-controlled value has already been embedded in the email template.
- CVE-2026-97718Critical
CVE-2026-97718 is a cross-site request forgery vulnerability in version 14.60 of the Secure Access server. Because of a bypassed security control, an attacker can cause an admin to create an account under their control.
- CVE-2026-116769Critical
CVE-2026-116769 is an authentication bypass vulnerability in Secure Access servers starting with version 13.0 and prior to 14.61. Attackers can modify security settings of a client via the server.
- CVE-2026-102435Critical
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.

The Joomla Custom Tables extension before 3.7.8 allows an unauthenticated attacker to upload a polyglot file with an attacker-controlled extension to the web-accessible tmp directory. The stored path is disclosed in the response, and the file is served as static content by default.

- CVE-2026-88811Critical
Missing filtering in the SUSE Rancher Manager meta proxy could cause passed-in Rancher credentials to be leaked to cloud providers. This affects SUSE Rancher 2.15.0 up to 2.15.3, 2.14.0 up to 2.14.7, and 2.13.0 up to 2.13.11.
- CVE-2026-105769Critical
kaniko before 1.25.20 can send a Microsoft Entra ID (Azure AD) access token for Azure Resource Manager to an attacker-controlled registry host. This is due to an unanchored regular expression in the ACR credential helper that accepts hostnames containing .azurecr.io, .azurecr.cn, .azurecr.de, or .azurecr.us.
- CVE-2026-94290Critical
The SUSE Rancher Fleet controller did not sufficiently restrict which kubeconfig secrets a Fleet Cluster object was allowed to reference. As a result, an ordinary user could define a cluster in a namespace they control and associate it with administrative credentials for the management cluster, causing the controller to manage the management cluster on that user's behalf with elevated privileges. This affects Fleet 0.16.0–0.16.3, 0.15.0–0.15.8, 0.14.0–0.14.12, 0.13.0–0.13.17 and possibly older versions.
Original NVD description (English source)
Qt 6 through 6.6 was discovered to contain a NULL pointer dereference via the function QXcbConnection::initializeAllAtoms(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server.
