CVE-2026-9277Patch

【即死系】npmパッケージshell-quoteに重大(Critical)なコマンドインジェクションの脆弱性。CVE-2026-9277はquote()において改行(\n)が認識されないもの。POSIXシェルでは改行はコマンド分割子として扱われるので終わり。バージョン1.1.0から1.8.3が脆弱。修正あり。 https://securityonline.info/shell-quote-command-injection-cve-2026-9277/

React Native patched a critical shell-quote RCE (CVE-2026-9277). The fix upgrades shell-quote to 1.8.4 in #57663. If you bundle RN tooling, check your lockfile. Android builds now send a default User-Agent that includes the app name and version (#58147). Expect analytics and middleware to see slightly different traffic. roundLayoutResultsToPixelGrid now skips non-owned subtrees (#58144). A layout perf fix hiding in plain sight. Maestro Cloud screenshot flows skip device-specific runs (#58166). Less flaky CI, fewer red herrings. build-types support 'react-native/react-private-interface' (#58075). Cleaner interop for private API shims. Jest quietly migrates CoverageReporter tests off mock-fs. Test hygiene, but the direction is right. The shell-quote fix is the one to pull first. #javascript https://repojournal.com/showcase/meta/2026-08-28/react-native-patches-critical-shell-quote-rce

CVE-2026-9277: shell-quote before 1.8.4 command injection in quote() https://www.openwall.com/lists/oss-security/2026/05/23/2 /(.)/g in JavaScript does not match line terminators, so a newline can pass through unescaped. In POSIX shells, a literal newline is a command separator.

React Native's dev-time attack surface just got smaller. The CLI dependency shell-quote was bumped to 1.8.4, closing CVE-2026-9277, a command injection flaw. If you run RN's tooling on untrusted input, this one matters; update your lockfile. Meta also gutted two device-specific screenshot flows in RNTester, skipping them in Maestro Cloud (#58166). The CI runner for RNTester is now wired in (#58151), so the skip is part of a wider test-strategy shift. Jest's coverage reporter test migrated off mock-fs (#16401). It's a cleanup, but it de-risks a test path that depended on a virtual filesystem. The props-to-interface conversion continues. More types now back React's private interface (#58075), part of a slow, deliberate type cleanup. Nothing flashy, but the diff churn is steady. RN's tooling now has one less known hole. The screenshot flows being skipped suggest Maestro Cloud's own device matrix is handling coverage. Jest's mock-fs exit is the quiet housekeeping that keeps the test suite honest. Dependency bumps for CVEs are unglamorous. This one is the rare day where the fix beats the feature. #javascript https://repojournal.com/showcase/meta/2026-08-27/react-native-kills-two-feature-flags-as-jest-scrubs-a-supply-chain-advisory

shell-quote critical RCE vulnerability (CVE-2026-9277) patched in claude-code-action; bump to 1.8.4 shipped immediately. AWS plugin delisted from official registry. No detail on why, but the move was clean. PR review context now includes diff hunks, so Claude sees the actual changed lines when commenting on reviews. Matters more than it sounds. Image attachment downloads now bounded. Fetch depth logic tightened to avoid unnecessary deep clones on already-shallow checkouts. Spot plugins updated across the board: Pinecone, SonarQube, Spanner, and Carta suite all got bumps. Routine maintenance, but the cadence is steady. #AI https://repojournal.com/showcase/anthropics/2026-08-15/shell-quote-critical-vulnerability-patched-aws-plugin-delisted-pr-review

A dependency can be present everywhere and exploitable almost nowhere — or present once in exactly the wrong execution path. CVE-2026-9277 in shell-quote is a good example of why package inventory alone does not answer the operational question. The vulnerable path involves attacker-influenced object tokens reaching quote(), followed by the resulting string being handed to a POSIX shell. That distinction matters when triaging a large Node.js estate. Finding shell-quote <=1.8.3 is the beginning of the investigation, not the end. The more important question is where application data crosses into shell execution and under which Unix identity, container, runner, or service account that command executes. **In practical terms, it is a good time to:** - identify shell-quote versions in package-lock.json, npm-shrinkwrap.json, pnpm-lock.yaml, and yarn.lock files - trace callers of quote() and parse() to determine whether object tokens can originate from external or transformed input - search Node.js code for child_process.exec(), execSync(), and shell: true near affected data flows - record the Unix user, capabilities, mounted secrets, and writable paths available to each reachable execution context - distinguish merely installed vulnerable packages from reachable vulnerable code in remediation tracking A vulnerability scanner can tell you where a package exists. How consistently can your team tell where its dangerous behavior is actually reachable? #LinuxSecurity #VulnerabilityManagement #DevSecOps #OpenSource #SecurityOperations https://linuxsecurity.com/news/security-vulnerabilities/shell-quote-command-injection-linux-commands

🚨Critical - shell-quote Command Injection Vulnerability (CVE-2026-9277) The shell-quote npm package contains a critical command injection vulnerability where the quote() function fails to escape line terminators (\n, \r) within object-token inputs. Successful exploitation could allow an attacker to bypass shell boundaries and execute arbitrary system commands with the privileges of the underlying Node.js process. 👉Affected: shell-quote >= 1.1.0, <= 1.8.3 | Fix: Upgrade to 1.8.4
