Required action: Apply updates per vendor instructions.
CVE-2013-0422
CriticalCVSS 9.8KEVSummary
Wielokrotne podatności w Oracle Java 7 przed aktualizacją 11 pozwalają zdalnym atakującym na wykonanie dowolnego kodu. Wykorzystują one metodę getMBeanInstantiator w klasie JmxMBeanServer oraz API refleksji, co umożliwia obejście zabezpieczeń.
Risk Assessment
Organizacje mogą być narażone na zdalne ataki, które mogą prowadzić do przejęcia kontroli nad systemami, co stwarza poważne zagrożenie dla bezpieczeństwa danych.
Recommendation
Zaleca się aktualizację Oracle Java do najnowszej wersji, aby usunąć te podatności oraz wdrożenie dodatkowych środków zabezpieczających, takich jak monitorowanie i ograniczenie dostępu do krytycznych systemów.

- CVE-2026-86596Critical
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.
- CVE-2026-105606Critical
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-2026-105604Critical
The Joomla DJ-Classifieds extension before 3.11.3 is vulnerable to an unauthenticated SQL injection in the frontend search.
- CVE-2026-105603Critical
The Joomla DJ-Classifieds extension before 3.11.3 is vulnerable to an unprivileged file upload, leading to full remote code execution (RCE).
- 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)
Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.
