Zoom and GitLab Patch RCE, DoS, and 2FA Bypass Vulnerabilities
Two of the world’s most critical business platforms just dropped emergency security patches that could prevent complete network takeovers and system shutdowns.
Zoom and GitLab released urgent updates to fix vulnerabilities affecting millions of organizations worldwide.
The breaking discovery? A single Zoom meeting participant could potentially execute remote code on enterprise network infrastructure, while GitLab users face multiple attack vectors that could crash entire development operations.
Both platforms serve as backbone infrastructure for remote work and software development, making these flaws particularly dangerous for business continuity. With organizations heavily dependent on these tools for daily operations, the window for exploitation remains massive.
The Zoom vulnerability
A security flaw in Zoom’s enterprise networking equipment could transform any meeting participant into a network administrator with malicious intentions. The vulnerability, designated CVE-2026-22844, earned a near-perfect severity score of 9.9 out of 10—essentially marking this as a “complete disaster” scenario for enterprise security.
This command injection vulnerability affects Zoom Node Multimedia Routers before version 5.2.1716.0, essentially handing any meeting participant the keys to compromise entire corporate network infrastructures. Picture this: someone joins your routine morning standup, and suddenly your entire network infrastructure could be compromised through something as simple as sending malicious commands.
Zoom’s internal security team discovered the flaw during routine testing earlier this week, though fortunately there’s no evidence of real-world exploitation yet. But security researchers emphasize that the combination of maximum severity and widespread deployment makes this a digital time bomb for enterprise users.
The vulnerability specifically targets organizations using Zoom Node Meetings, Hybrid, or Meeting Connector deployments—enterprise-grade solutions deployed across thousands of corporations globally. Recent security bulletins show this represents Zoom’s highest-severity vulnerability disclosure in recent memory, prompting immediate update recommendations for all affected enterprise customers.
GitLab’s security issue
GitLab users are staring down an even more complex threat landscape with multiple high-severity vulnerabilities creating a perfect storm of attack opportunities. Emergency patches released this week address five separate security flaws affecting both Community and Enterprise editions, including denial-of-service attacks and two-factor authentication bypasses.
The standout threat, CVE-2025-13927, allows completely unauthenticated attackers to crash GitLab instances by sending specially crafted requests with malformed authentication data. Think about that scenario—no login required, just the right malicious payload, and entire development operations could grind to a halt.
This vulnerability landscape builds on concerning patterns identified in recent months. Three months ago, GitLab revealed similar authentication handling weaknesses, suggesting it has been wrestling with systemic security challenges across its platform architecture.
The current vulnerabilities span multiple attack vectors, from resource exhaustion in event collection to JSON validation exploits in GraphQL requests. Four months ago, GitLab’s API endpoints remain vulnerable to denial-of-service attacks, with CVSS scores ranging from 6.5 to 8.5 across different vulnerability types—a troubling trend that continues with this week’s disclosures.
What this means for your organization
The convergence of these vulnerabilities creates an unprecedented security emergency for enterprise users. Organizations running affected Zoom enterprise equipment face the immediate risk of complete network compromise through something as routine as a scheduled team meeting. Meanwhile, GitLab users could witness their entire development pipeline shut down by attackers who don’t even need login credentials.
The action items are crystal clear and urgent: Zoom users must immediately upgrade to MMR version 5.2.1716.0 or later, while GitLab administrators need to implement the latest patches across all Community and Enterprise installations.
Don’t wait for the next security briefing or scheduled maintenance window. These aren’t routine updates—they’re emergency patches.
