An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-23392 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- locutus (npm): affected all versions; fixed in 2.0.15\n- locutus (npm): affected all versions; fixed in 2.0.15\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-2021-23392/ (Markdown: https://insights.sbomify.com/CVE-2021-23392/index.md)","id":"CVE-2021-23392","markdown":"https://insights.sbomify.com/CVE-2021-23392/index.md","name":"CVE-2021-23392","record":{"aliases":["GHSA-39q4-p535-c852","SNYK-JS-LOCUTUS-1090597"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript utility library","requires_auth":"none","summary":"Attackers can cause denial of service in applications using the locutus library via a crafted input to the gopher_parsedir function.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"locutus","vendor":"locutus"}],"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":[],"description":"The package locutus before 2.0.15 are vulnerable to Regular Expression Denial of Service (ReDoS) via the gopher_parsedir function.","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":"Regular Expression Denial of Service (ReDoS)","id":"CVE-2021-23392","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":2,"n_references":3,"next":{"headline":"Open Redirect","id":"CVE-2021-23393"},"packages":[{"ecosystem":"npm","fixed":["2.0.15"],"introduced":["0"],"last_affected":[],"package":"locutus","purl":null,"source":"GHSA-39q4-p535-c852"},{"ecosystem":"npm","fixed":["2.0.15"],"introduced":["0"],"last_affected":[],"package":"locutus","purl":"pkg:npm/locutus","source":"GHSA-39q4-p535-c852"}],"prev":{"headline":"Arbitrary File Write via Archive Extraction (Zip Slip)","id":"CVE-2021-23391"},"products":["locutus"],"published":"2021-06-08","related":[{"cvss_score":9.8,"headline":"Locutus: RCE via unsanitized input in create_function()","id":"CVE-2026-32304","kev_date_added":null,"published":"2026-03-12"},{"cvss_score":9.8,"headline":"Prototype Pollution","id":"CVE-2020-7719","kev_date_added":null,"published":"2020-09-01"},{"cvss_score":9.4,"headline":"Locutus is vulnerable to Prototype Pollution","id":"CVE-2026-25521","kev_date_added":null,"published":"2026-02-04"},{"cvss_score":8.1,"headline":"Locutus: Remote Code Execution (RCE) in locutus call_user_func_array due to Code Injection","id":"CVE-2026-29091","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":6.9,"headline":"Locutus has Prototype Pollution via __proto__ Key Injection in unserialize()","id":"CVE-2026-33993","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":6.3,"headline":"Locutus Prototype Pollution due to incomplete fix for CVE-2026-25521","id":"CVE-2026-33994","kev_date_added":null,"published":"2026-03-27"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"Attackers can cause denial of service in applications using the locutus library via a crafted input to the gopher_parsedir function.","url":"https://insights.sbomify.com/CVE-2021-23392/"}
