Drupal has issued an alert stating that it intends to release a "core security release" for all supported branches on May 20, 2026, from 5-9 p.m. UTC. "The Drupal Security Team urges you to reserve time for core updates at that time because exploits might be developed within hours or days," the maintainers of the PHP-based content management system (CMS) said . "Not all configurations are affected. Reserve time on May 20 during the release window to determine whether your sites are affected and in need of an immediate update. Mitigation information will be included in the advisory." It's being advised to update to the latest supported patch for the site's version of Drupal before the deadline so that any outstanding upgrade issues can be addressed. Patches are expected to be available for the following supported branches of Drupal core - 11.3.x 11.2.x 10.6.x 10.5.x "Sites on one of these supported versions should updat...

Critical security vulnerabilities have been disclosed in SEPPMail Secure E-Mail Gateway , an enterprise-grade email security solution, that could be exploited to achieve remote code execution and enable an attacker to read arbitrary mails from the virtual appliance. "These vulnerabilities could have been exploited to read all mail traffic or as an entry vector into the internal network," InfoGuard Labs researchers Dario Weiss, Manuel Feifel, and Olivier Becker said in a Monday report. The list of identified flaws is as follows - CVE-2026-2743 (CVSS score: 10.0) - A path traversal vulnerability in the SeppMail User Web Interface's large file transfer (LFT) feature that could enable arbitrary file write, resulting in remote code execution. CVE-2026-7864 (CVSS score: 6.9) - An exposure of sensitive system information vulnerability that leaks server environment variables through an unauthenticated endpoint in the new GINA UI. CVE-2026-44125 (CVSS score: 9.3) - A mi...

Monday opens with a trust problem. A mail server flaw is under active use. A network control system was targeted. Trusted packages were poisoned. A fake model page pushed a stealer. Then came the familiar ransom claim: the data was returned and deleted. The pattern is clear. One weak dependency can leak keys. One leaked key can open cloud access. One cloud foothold can become a production incident. AI is speeding up vulnerability discovery, attackers are moving quickly, and old exposure still keeps paying off. Patch the quiet risks first. Let’s get into it. ⚡ Threat of the Week On-Prem Microsoft Exchange Server Exploited in the Wild —Microsoft disclosed a security vulnerability impacting on-premise versions of Exchange Server, which has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-42897 (CVSS score: 8.1), has been described as a spoofing bug stemming from a cross-site scripting flaw.

Ivanti, Fortinet, n8n, SAP, and VMware have released security fixes for various vulnerabilities that could be exploited by bad actors to bypass authentication and execute arbitrary code. Topping the list is a critical flaw impacting Ivanti Xtraction (CVE-2026-8043, CVSS score: 9.6) that could be exploited to achieve information disclosure or client-side attacks. "External control of a file name in Ivanti Xtraction before version 2026.2 allows a remote authenticated attacker to read sensitive files and write arbitrary HTML files to a web directory, leading to information disclosure and possible client-side attacks," Ivanti said in an advisory. Fortinet published advisories for two critical shortcomings affecting FortiAuthenticator and FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS that could result in code execution - CVE-2026-44277 (CVSS score: 9.1) - An improper access control vulnerability in FortiAuthenticator that may allow an unauthenticated attacker to...

Chaotic Eclipse, the security researcher behind the recently disclosed Windows flaws, YellowKey and GreenPlasma , has released a proof-of-concept (PoC) for a Windows privilege escalation zero-day flaw that grants attackers SYSTEM privileges on fully patched Windows systems. Codenamed MiniPlasma , the vulnerability impacts "cldflt.sys," which refers to the Windows Cloud Files Mini Filter Driver, and resides in a routine named "HsmOsBlockPlaceholderAccess." It was originally reported to Microsoft by Google Project Zero researcher James Forshaw in September 2020. Although it was assumed that the shortcoming was fixed by Microsoft in December 2020 as part of CVE-2020-17103 , Chaotic Eclipse said further investigation has uncovered that the "exact same issue [...] is actually still present, unpatched." "I'm unsure if Microsoft just never patched the issue or the patch was silently rolled back at some point for unknown reasons. The original PoC by...
