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-2020-7774 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- y18n (npm): affected all versions; fixed in 3.2.2\n- y18n (npm): affected all versions; fixed in 3.2.2\n- y18n (npm): affected from 4.0.0; fixed in 4.0.1\n- y18n (npm): affected from 4.0.0; fixed in 4.0.1\n- y18n (npm): affected from 5.0.0; fixed in 5.0.5\n- y18n (npm): affected from 5.0.0; fixed in 5.0.5\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-2020-7774/ (Markdown: https://insights.sbomify.com/CVE-2020-7774/index.md)","id":"CVE-2020-7774","markdown":"https://insights.sbomify.com/CVE-2020-7774/index.md","name":"CVE-2020-7774","record":{"aliases":["ALPINE-CVE-2020-7774","CLEANSTART-2026-SV85138","CLEANSTART-2026-UW35844","CLSA-2026-1782867615","DEBIAN-CVE-2020-7774","GHSA-c4w7-xm78-47vh","ROOT-APP-NPM-CVE-2020-7774","UBUNTU-CVE-2020-7774"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript library","requires_auth":"none","summary":"Prototype pollution in the y18n library allows attackers to modify object prototypes, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"graalvm","vendor":"oracle"},{"product":"sinec_infrastructure_network_services","vendor":"siemens"},{"product":"y18n","vendor":"y18n_project"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L/E:P","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"The package y18n before 3.2.2, 4.0.1 and 5.0.5, is vulnerable to Prototype Pollution.","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":"Prototype Pollution","id":"CVE-2020-7774","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"oracle:graalvm","products":["oracle:graalvm","siemens:sinec_infrastructure_network_services"],"type":"other","year":"2020"},"n_packages":6,"n_references":6,"next":{"headline":"Command Injection","id":"CVE-2020-7775"},"packages":[{"ecosystem":"npm","fixed":["3.2.2"],"introduced":["0"],"last_affected":[],"package":"y18n","purl":null,"source":"GHSA-c4w7-xm78-47vh"},{"ecosystem":"npm","fixed":["3.2.2"],"introduced":["0"],"last_affected":[],"package":"y18n","purl":"pkg:npm/y18n","source":"GHSA-c4w7-xm78-47vh"},{"ecosystem":"npm","fixed":["4.0.1"],"introduced":["4.0.0"],"last_affected":[],"package":"y18n","purl":null,"source":"GHSA-c4w7-xm78-47vh"},{"ecosystem":"npm","fixed":["4.0.1"],"introduced":["4.0.0"],"last_affected":[],"package":"y18n","purl":"pkg:npm/y18n","source":"GHSA-c4w7-xm78-47vh"},{"ecosystem":"npm","fixed":["5.0.5"],"introduced":["5.0.0"],"last_affected":[],"package":"y18n","purl":null,"source":"GHSA-c4w7-xm78-47vh"},{"ecosystem":"npm","fixed":["5.0.5"],"introduced":["5.0.0"],"last_affected":[],"package":"y18n","purl":"pkg:npm/y18n","source":"GHSA-c4w7-xm78-47vh"}],"prev":{"headline":"Cross-site Scripting (XSS)","id":"CVE-2020-7773"},"products":["y18n"],"published":"2020-11-17","related":[{"cvss_score":8.6,"headline":"Security feature bypass in Oracle GraalVM Enterprise Edition","id":"CVE-2025-50059","kev_date_added":null,"published":"2025-07-15"},{"cvss_score":8.2,"headline":"Arbitrary File Creation/Overwrite via insufficient symlink protection due to directory cache poisoning","id":"CVE-2021-32803","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":8.2,"headline":"Arbitrary File Creation/Overwrite due to insufficient absolute path sanitization","id":"CVE-2021-32804","kev_date_added":null,"published":"2021-08-03"},{"cvss_score":8.1,"headline":"Code injection in Oracle GraalVM Enterprise Edition","id":"CVE-2025-30749","kev_date_added":null,"published":"2025-07-15"},{"cvss_score":8.1,"headline":"Code injection in Oracle GraalVM Enterprise Edition","id":"CVE-2025-50106","kev_date_added":null,"published":"2025-07-15"},{"cvss_score":7.8,"headline":"Privilege escalation in Oracle GraalVM Enterprise Edition","id":"CVE-2026-62574","kev_date_added":null,"published":"2026-07-21"},{"cvss_score":7.7,"headline":"Denial of service in GraalVM Enterprise Edition","id":"CVE-2020-2802","kev_date_added":null,"published":"2020-04-15"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"Prototype pollution in the y18n library allows attackers to modify object prototypes, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2020-7774/"}
