About this tag
CVE-2026-33750 is a denial-of-service vulnerability in the brace-expansion package, as described by Microsoft. The flaw involves a zero-step sequence that causes the process to hang and exhaust memory, leading to a sustained denial of service. An attacker can exploit this by providing a crafted brace pattern with a zero step value, causing the sequence generator to loop indefinitely. This does not require code execution, only the ability to supply malicious input to the affected component. The result is a total loss of availability, making this CVE operationally serious. Discussions on WindowsForum highlight the impact and provide example payloads, emphasizing the need for patching or mitigation.
