CVE-2025-11953 React Native Community CVE debrief

CVE-2025-11953 is a React Native Community CLI OS command injection vulnerability that CISA added to its Known Exploited Vulnerabilities catalog on the same date the CVE was published. Because the supplied corpus is limited to KEV metadata and official references, the exact affected versions, trigger conditions, and remediation details are not included here. The safest takeaway is that organizations using the CLI should treat this as a high-priority tooling issue and follow vendor guidance as soon as it is available.

Who should care

Teams that use React Native Community CLI in development workflows, build pipelines, or CI/CD; security teams managing KEV-driven remediation; and maintainers of systems that invoke the CLI in automated or privileged contexts.

Technical summary

The available source material identifies the issue as an OS command injection vulnerability in React Native Community CLI. CISA’s KEV entry confirms it as a known exploited vulnerability and links to the vendor repository commit and pull request, plus the NVD record. No affected versions, attack path details, or proof-of-concept information are present in the supplied corpus, so those specifics should be obtained directly from the vendor references before making change decisions.

Defensive priority

High. CISA KEV inclusion means this should be prioritized for remediation over non-KEV issues, especially where the CLI is used in trusted automation or systems with broad filesystem or shell access. The KEV due date provided in the source metadata is 2026-02-26.

Recommended defensive actions

  • Identify where React Native Community CLI is installed or invoked, including developer workstations and CI/CD runners.
  • Review the vendor commit and pull request referenced by CISA for the fixed version or mitigation guidance.
  • Upgrade to a vendor-supplied fixed release or apply the vendor’s mitigation as soon as it is confirmed.
  • If no mitigation is available, discontinue use of the affected component or isolate it from high-trust execution contexts.
  • Restrict shell and subprocess execution privileges for build and automation environments that use the CLI.
  • Validate downstream tools and scripts that call the CLI so they cannot pass untrusted input into command construction.
  • Track remediation to the CISA KEV due date supplied in the metadata: 2026-02-26.

Evidence notes

All statements are based only on the supplied source corpus: the CISA KEV entry, its metadata fields, and the official reference links it names (CVE.org, NVD, the vendor repository commit, and the vendor pull request). The corpus confirms the vulnerability type as OS command injection, that it is KEV-listed, and that the known-ransomware-campaign-use field is Unknown. It does not provide exploit details, affected versions, or vendor fix text, so those are intentionally not asserted here.
