CSRF Flaw in Elementor Allows Admin Account Creation on Over 2 Million WordPress Sites
A CSRF vulnerability in the Elementor page builder plugin affects more than 2 million WordPress sites, allowing attackers to create administrator accounts on vulnerable installations.
The flaw impacts versions 4.3.0 and 4.3.1, which together account for over 2 million active installations. Elementor itself is present in more than 10 million WordPress sites. The vulnerability received a CVSS score of 8.8, placing it in the high severity range. At the time of public disclosure on September 26, no CVE identifier had been assigned.
The root cause lies in the Editor Events module, which fails to properly enforce CSRF protections on cookie-authenticated requests to the WordPress REST API. By appending the parameter elementor/v1/events/ as a query string, any REST request bypasses the plugin's verification checks. This occurs because the browser automatically includes session cookies with every request, and the plugin does not confirm whether the request originated from the legitimate site dashboard.
The attack requires no special form, JavaScript, or attacker-controlled webpage. A simple link, such as an anchor in an email or instant message, is sufficient. When a logged-in administrator clicks the link, the browser sends an authenticated request that, on a default installation, results in the creation of a second administrator account.
Beyond the plugin itself, the flaw exposes the entire surface of the WordPress REST API, including core endpoints and routes provided by other plugins installed on the same site. The issue was discovered by researcher Saggre and resolved through responsible disclosure. The fix was released in version 4.3.2. Site owners running the affected versions should update immediately. At the time of analysis, no public evidence of active exploitation had been recorded.

Use-After-Free in HTTP/2 Upload Leads to Potential RCE in curl: Detailed Analysis of CVE-2026-92392
In curl 8.23.0, developers fixed a high-severity Use-After-Free vulnerability tracked as CVE-2026-92392 that could allow remote code execution during HTTP/2 uploads. The flaw stems from a dangling pointer left on an easy handle after a server resets an HTTP/2 stream, which later gets dereferenced when the multi handle closes. An attacker controlling the server can influence memory contents to hijack a function pointer and execute arbitrary code, though successful exploitation requires precise conditions including upload size, memory layout, and knowledge of the target architecture. The issue was discovered by Luna Tong at Anthropic using their OSS Scanner and reported to the curl security team on September 15. The team accelerated the release cycle by two weeks to deliver the fix while maintaining standard procedures. curl maintainers continue reducing internal handle pointers in favor of identifiers and are adding more tests and static analysis to prevent similar memory-safety errors. The vulnerability highlights ongoing risks in C-based networking code handling multiplexed protocols like HTTP/2.
Automating Asset Scanning in MaxPatrol VM via API: Part 4 on Authentication
A detailed technical guide explains how to build asset scanning automation in MaxPatrol VM using its API, starting with authentication methods. The author covers three authorization options including local account login-password, domain account credentials, and reference tokens, providing working Python examples for local accounts. Code reads secrets from an .env file and obtains a Bearer token valid for 24 hours from the Core role instance. The post details required privileges in both the Management Console and MaxPatrol 10 for tasks such as vulnerability exports, dynamic asset group management, scan task creation, and report exporting. It credits Alexey Leonov for an early GitHub script that enabled practical API usage and lists additional resources including webinars, SDK, CLI, Jira integration, and a Postman collection. All subsequent API calls rely on the generated headers containing the Bearer token.
Securing Hadoop Clusters: Removing Passwords from XML Configs with Credential Provider API and JCEKS
Hadoop configurations frequently expose sensitive credentials such as database passwords and cloud access keys in plain text within files like hive-site.xml and core-site.xml. The Credential Provider API, introduced in Hadoop 2.6, allows applications to retrieve secrets from an external JCEKS keystore instead of embedding them directly in XML. This mechanism uses conf.getPassword() to fetch decrypted values from the keystore when hadoop.security.credential.provider.path is configured. JCEKS relies on the outdated PBEWithMD5AndTripleDES algorithm, which remains vulnerable to Sweet32 attacks in theory though practical risk for small keystore files is low. Master password protection for the keystore itself is the weakest link, with options including environment variables, protected password files, or HDFS Transparent Data Encryption. Arenadata has automated credential encryption management in its ADH platform through ADCM to handle keystore creation, permission setting, and rotation across cluster nodes.
CISA Adds Five Exploited Vulnerabilities to KEV Catalog Including AhsayCBS Authentication and Command Injection Flaws
The US Cybersecurity and Infrastructure Security Agency (CISA) has added five vulnerabilities to its Known Exploited Vulnerabilities catalog after confirming active exploitation in the wild. Four vulnerabilities were registered on October 14, 2026, and one additional entry followed on October 15. Among the newly listed issues are two critical flaws affecting the AhsayCBS backup management server: CVE-2026-105133, an authentication bypass in the API, and CVE-2026-105134, a command injection vulnerability in the replication feature. When chained together, the pair allows unauthenticated remote attackers to execute arbitrary operating system commands. Vendor Ahsay has released hotfixes in versions 10.3.4.45 and 9.15.2.70 because standard patches cannot fully address the issues. The advisory also references vulnerabilities in Atlassian products and multiple network security solutions from other vendors.
