Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-116576/ (Markdown: https://insights.sbomify.com/CVE-2026-116576/index.md)","id":"CVE-2026-116576","markdown":"https://insights.sbomify.com/CVE-2026-116576/index.md","name":"CVE-2026-116576","record":{"aliases":["DEBIAN-CVE-2026-116576","ECHO-4768-9cb7-856f","GHSA-3f7j-7jwc-fxfj","UBUNTU-CVE-2026-116576"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"systeminformation is a System and OS information library for node.js. Prior to 5.33.16, services() in lib/processes.js inserts a caller-supplied service name into a PowerShell Get-CimInstance filter after processing it with sanitizeShellString() in lib/util.js. On Windows, the sanitizer removes ASCII quotes but permits Unicode quotation marks that PowerShell accepts as string delimiters, allowing crafted input to terminate the filter and place a PowerShell expression in the command executed by util.powerShell(). The expression runs with the Node.js process account's permissions and may read or change accessible files, alter application data, or disrupt the service. The package does not expose a network service itself, so remote reachability depends on a consuming application forwarding attacker-controlled input to services() or getDynamicData(). This issue is fixed in version 5.33.16.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"systeminformation: Windows command injection in services() through Unicode quotation marks","id":"CVE-2026-116576","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"Tornado: Quadratic CPU usage when parsing HTTP headers with line folding","id":"CVE-2026-116577"},"packages":[{"ecosystem":"npm","fixed":["5.33.16"],"introduced":["0"],"last_affected":[],"package":"systeminformation","purl":null,"source":"GHSA-3f7j-7jwc-fxfj"},{"ecosystem":"npm","fixed":["5.33.16"],"introduced":["0"],"last_affected":[],"package":"systeminformation","purl":"pkg:npm/systeminformation","source":"GHSA-3f7j-7jwc-fxfj"}],"prev":{"headline":"Mem0: Cross-tenant conversation leak via unescaped delimiter collision in session-scope key (_build_session_scope)","id":"CVE-2026-116575"},"products":["systeminformation"],"published":"2026-10-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-26","vendors":["sebhildebrandt"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-116576/"}
