CVE-2026-74820: ServiceNow vulnerability
CVE-2026-74820 affects ServiceNow. The published description indicates a remote or untrusted-network exploitation path.
What happened
A security weakness in ServiceNow is being tracked as CVE-2026-74820. CVE-2026-74820 affects ServiceNow. ServiceNow has remediated a SQL injection vulnerability that was identified in in the ServiceNow AI platform.
The company said it deployed a security update to hosted instances and provided the update to its partners and self-hosted customers, which leaves organizations that run their. ServiceNow deployed a security update to hosted instances and ServiceNow prov. ServiceNow released security patches for three new maximum-severity AI Platform vulnerabilities that can be exploited in code injection, SQL injection, and privilege escalation attacks.
Three CVSS 10 0 ServiceNow Flaws Could Let Unauthenticated Attackers Execute Code and SQL. The reported consequence is code execution, meaning successful exploitation could make the affected application or process run attacker-controlled code. ServiceNow has released patches for four security flaws impacting the ServiceNow AI Platform, three of them rated 10.
This vulnerability could enable an unauthenticated user, in certain circumstances, to execute arbitrary SQL statements against the instance's underlying database and gain access to, or modify, instance data beyond what was intended. This vulnerability could enable an unaut. The published description indicates a remote or untrusted-network exploitation path.
Editorial note: this News Brief follows the available evidence and adds length only when additional facts or useful context are available. Where public reporting does not establish a specific victim sequence, CyberDeltaForce does not present one as fact.
What the reporting and advisory establish

ServiceNow warns of three max severity security vulnerabilities
A security weakness in ServiceNow is being tracked as CVE-2026-74820. The flaw is described as a SQL injection vulnerability. SQL injection occurs when untrusted input changes the meaning of a database query. Successful exploitation can expose, alter or delete data and can sometimes become a wider application compromise. The available description indicates that the vulnerable path can be reached remotely or from an untrusted network, so the exposure of ServiceNow becomes part of the attack condition. The reported consequence is code execution, meaning successful exploitation could make the affected application or process run attacker-controlled code.
What this means for your environment
Move from the published facts to the technical path, exposure conditions and defensive decisions that matter in a real environment.
Attack & Exploitation Path
The sequence below shows how the vulnerability can be reached and what successful exploitation can produce. Each stage is labeled by evidence status.
an affected ServiceNow instance is reachable from a network or remote position available to the attacker.
attacker-controlled network input reaches the vulnerable code path on the affected service.
the SQL injection condition is triggered inside ServiceNow, creating the security boundary failure described by the advisory.
successful exploitation can result in attacker-controlled code execution in the affected application or process.
the practical reach of successful code execution depends on the privileges and resources available to the affected process.
Why this matters to you
CVE-2026-74820 matters because the practical risk is not the score alone — it is whether ServiceNow exists in your environment and whether the reported trigger or exposure path can reach it. The current severity is CRITICAL 10. No exploitation flag is currently present in the CDF data, but that does not remove the need to validate affected systems.
Does this deserve attention in my environment?
Check the conditions below against your use of ServiceNow.
Select the conditions that are true in your environment. Leaving a condition unselected does not mean you are safe — it only means you have not marked it as applicable.
- Search endpoint, software and asset inventory for ServiceNow.
- Confirm the vendor-recommended fixed version or mitigation and verify deployment, not just assignment, across affected assets.
- Review relevant endpoint, application, network or identity telemetry for activity associated with exploitation of the affected component.
- Track vendor and government guidance for any change in exploitation status while remediation is underway.
What remains unconfirmed
- Available reporting does not currently indicate exploitation, but that can change as vendor, government or threat-intelligence reporting develops.
