High-severity SharePoint RCE bug patched by Microsoft (CVE-2026-45659)

Help Net Security

Microsoft has patched a serious remote code execution vulnerability in SharePoint, identified as CVE-2026-45659. This flaw impacts SharePoint Server Subscription Edition, SharePoint Server 2019, and SharePoint Enterprise Server 2016. The vulnerability arises from the way SharePoint handles untrusted data, allowing an authenticated attacker to execute code on a vulnerable server without requiring any user interaction. The simplicity of the attack makes it particularly concerning, as it poses a risk to organizations using these versions of SharePoint. Companies should prioritize applying the patches to safeguard their systems from potential exploitation.

MFA Prompt Bombing: Why Your Second Factor Isn't Saving You

The Hacker News

Multi-factor authentication (MFA) was designed to enhance security by requiring users to provide a second form of verification, making it harder for attackers to gain access to accounts. However, researchers have found that some attackers are using a technique called MFA prompt bombing, where they bombard users with repeated authentication requests until they inadvertently approve one. This method takes advantage of users being overwhelmed and mistakenly granting access. As a result, organizations that rely solely on MFA may be putting themselves at risk, as this approach can easily bypass the intended security measures. It's essential for companies to educate their employees about this tactic and consider additional security layers to protect against unauthorized access.
