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-2022-25918 exists.\n\nAffected packages and fixed versions:\n- shescape (npm): affected from 1.5.10; fixed in 1.6.1\n- shescape (npm): affected from 1.5.10; fixed in 1.6.1\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-2022-25918/ (Markdown: https://insights.sbomify.com/CVE-2022-25918/index.md)","id":"CVE-2022-25918","markdown":"https://insights.sbomify.com/CVE-2022-25918/index.md","name":"CVE-2022-25918","record":{"aliases":["GHSA-cr84-xvw4-qx3c"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"npm shescape library","requires_auth":"none","summary":"Attackers can cause denial of service in applications using the shescape library by triggering inefficient regular expressions during argument escaping.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"shescape","vendor":"shescape_project"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"The package shescape from 1.5.10 and before 1.6.1 are vulnerable to Regular Expression Denial of Service (ReDoS) via the escape function in index.js, due to the usage of insecure regex in the escapeArgBash function.","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":"Regular Expression Denial of Service (ReDoS)","id":"CVE-2022-25918","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":2,"n_references":4,"next":{"headline":"This candidate was in a CNA pool that was not assigned to any issues during 2022.","id":"CVE-2022-25920"},"packages":[{"ecosystem":"npm","fixed":["1.6.1"],"introduced":["1.5.10"],"last_affected":[],"package":"shescape","purl":null,"source":"GHSA-cr84-xvw4-qx3c"},{"ecosystem":"npm","fixed":["1.6.1"],"introduced":["1.5.10"],"last_affected":[],"package":"shescape","purl":"pkg:npm/shescape","source":"GHSA-cr84-xvw4-qx3c"}],"prev":{"headline":"Denial of service in Intel(R) Server Board M50CYP Family","id":"CVE-2022-25917"},"products":["shescape"],"published":"2022-10-27","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":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":"partial"},"state":"PUBLISHED","updated":"2025-05-05","vendors":["n/a"]},"summary":"Attackers can cause denial of service in applications using the shescape library by triggering inefficient regular expressions during argument escaping.","url":"https://insights.sbomify.com/CVE-2022-25918/"}
