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-2022-31180 exists.\n\nAffected packages and fixed versions:\n- shescape (npm): affected from 1.4.0; fixed in 1.5.8\n- shescape (npm): affected from 1.4.0; 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-2022-31180/ (Markdown: https://insights.sbomify.com/CVE-2022-31180/index.md)","id":"CVE-2022-31180","markdown":"https://insights.sbomify.com/CVE-2022-31180/index.md","name":"CVE-2022-31180","record":{"aliases":["GHSA-44vr-rwwj-p88h"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"JavaScript shell escape library","requires_auth":"none","summary":"Attackers can execute arbitrary commands via whitespace injection in shescape when interpolation is enabled, requiring an upgrade to patched versions.","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":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/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. Affected versions were found to have insufficient escaping of white space when interpolating output. This issue only impacts users that use the `escape` or `escapeAll` functions with the `interpolation` option set to `true`. The result is that if an attacker is able to include whitespace in their input they can: 1. Invoke shell-specific behaviour through shell-specific special characters inserted directly after whitespace. 2. Invoke shell-specific behaviour through shell-specific special characters inserted or appearing after line terminating characters. 3. Invoke arbitrary commands by inserting a line feed character. 4. Invoke arbitrary commands by inserting a carriage return character. Behaviour number 1 has been patched in [v1.5.7] which you can upgrade to now. No further changes are required. Behaviour number 2, 3, and 4 have been patched in [v1.5.8] which you can upgrade to now. No further changes are required. The best workaround is to avoid having to use the `interpolation: true` option - in most cases using an alternative is possible, see [the recipes](https://github.com/ericcornelissen/shescape#recipes) for recommendations. Alternatively, users may strip all whitespace from user input. Note that this is error prone, for example: for PowerShell this requires stripping `'\\u0085'` which is not included in JavaScript's definition of `\\s` for Regular Expressions.","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 whitespace in shescape","id":"CVE-2022-31180","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"command_injection","year":"2022"},"n_packages":2,"n_references":5,"next":{"headline":"Remote code execution in prestashop","id":"CVE-2022-31181"},"packages":[{"ecosystem":"npm","fixed":["1.5.8"],"introduced":["1.4.0"],"last_affected":[],"package":"shescape","purl":null,"source":"GHSA-44vr-rwwj-p88h"},{"ecosystem":"npm","fixed":["1.5.8"],"introduced":["1.4.0"],"last_affected":[],"package":"shescape","purl":"pkg:npm/shescape","source":"GHSA-44vr-rwwj-p88h"}],"prev":{"headline":"Insufficient escaping of line feeds for CMD in shescape","id":"CVE-2022-31179"},"products":["shescape"],"published":"2022-08-01","related":[{"cvss_score":8.1,"headline":"Insufficient escaping of line feeds for CMD in shescape","id":"CVE-2022-31179","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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-22","vendors":["ericcornelissen"]},"summary":"Attackers can execute arbitrary commands via whitespace injection in shescape when interpolation is enabled, requiring an upgrade to patched versions.","url":"https://insights.sbomify.com/CVE-2022-31180/"}
