Severity: critical · Patch status: patched · Since 2026-02-05 · CVE-2025-11953
React Native Community CLI contains an OS command injection vulnerability which could allow unauthenticated network attackers to send POST requests to the Metro Development Server and run arbitrary executables via a vulnerable endpoint exposed by the server. On Windows, attackers can also execute arbitrary shell commands with fully controlled arguments. CISA added CVE-2025-11953 to its Known Exploited Vulnerabilities catalog on Feb 5, 2026, which means attackers are exploiting it in the wild.
What to do
- Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
- US federal agencies must remediate by Feb 26, 2026 (BOD 22-01); treat that as the outer limit.
