An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-31179 exists.\n\nAffected packages and fixed versions:\n- shescape (npm): affected all versions; fixed in 1.5.8\n- shescape (npm): affected all versions; fixed in 1.5.8\n\nTask:\n1. 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-2022-31179/ (Markdown: https://insights.sbomify.com/CVE-2022-31179/index.md)","id":"CVE-2022-31179","markdown":"https://insights.sbomify.com/CVE-2022-31179/index.md","name":"CVE-2022-31179","record":{"aliases":["GHSA-jjc5-fp7p-6f8w"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript shell escape library","requires_auth":"none","summary":"Attackers can inject commands into cmd.exe on Windows by exploiting insufficient line feed escaping in the shescape library.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"shescape","vendor":"shescape_project"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Shescape is a simple shell escape package for JavaScript. Versions prior to 1.5.8 were found to be subject to code injection on windows. This impacts users that use Shescape (any API function) to escape arguments for cmd.exe on Windows An attacker can omit all arguments following their input by including a line feed character (`'\\n'`) in the payload. This bug has been patched in [v1.5.8] which you can upgrade to now. No further changes are required. Alternatively, line feed characters (`'\\n'`) can be stripped out manually or the user input can be made the last argument (this only limits the impact).","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Insufficient escaping of line feeds for CMD in shescape","id":"CVE-2022-31179","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"command_injection","year":"2022"},"n_packages":2,"n_references":3,"next":{"headline":"Insufficient escaping of whitespace in shescape","id":"CVE-2022-31180"},"packages":[{"ecosystem":"npm","fixed":["1.5.8"],"introduced":["0"],"last_affected":[],"package":"shescape","purl":null,"source":"GHSA-jjc5-fp7p-6f8w"},{"ecosystem":"npm","fixed":["1.5.8"],"introduced":["0"],"last_affected":[],"package":"shescape","purl":"pkg:npm/shescape","source":"GHSA-jjc5-fp7p-6f8w"}],"prev":{"headline":"Improper Authorization in eLabFTW","id":"CVE-2022-31178"},"products":["shescape"],"published":"2022-08-01","related":[{"cvss_score":9.8,"headline":"Insufficient escaping of whitespace in shescape","id":"CVE-2022-31180","kev_date_added":null,"published":"2022-08-01"},{"cvss_score":6.9,"headline":"Shescape escape() leaves bracket glob expansion active on Bash, BusyBox, and Dash","id":"CVE-2026-32094","kev_date_added":null,"published":"2026-03-11"},{"cvss_score":6.5,"headline":"Shescape on Windows escaping may be bypassed in threaded context","id":"CVE-2023-40185","kev_date_added":null,"published":"2023-08-23"},{"cvss_score":6.3,"headline":"Null characters not escaped in shescape","id":"CVE-2021-21384","kev_date_added":null,"published":"2021-03-18"},{"cvss_score":6.2,"headline":"Exposure of home directory through shescape on Unix with Bash","id":"CVE-2022-24725","kev_date_added":null,"published":"2022-03-03"},{"cvss_score":5.9,"headline":"Shescape Inefficient Regular Expression Complexity vulnerability","id":"CVE-2022-36064","kev_date_added":null,"published":"2022-09-06"}],"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-22","vendors":["ericcornelissen"]},"summary":"Attackers can inject commands into cmd.exe on Windows by exploiting insufficient line feed escaping in the shescape library.","url":"https://insights.sbomify.com/CVE-2022-31179/"}
