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-2022-25927 exists.\n\nAffected packages and fixed versions:\n- ua-parser-js (npm): affected from 0.7.30; fixed in 0.7.33\n- ua-parser-js (npm): affected from 0.7.30; fixed in 0.7.33\n- ua-parser-js (npm): affected from 0.8.0; fixed in 1.0.33\n- ua-parser-js (npm): affected from 0.8.0; fixed in 1.0.33\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-2022-25927/ (Markdown: https://insights.sbomify.com/CVE-2022-25927/index.md)","id":"CVE-2022-25927","markdown":"https://insights.sbomify.com/CVE-2022-25927/index.md","name":"CVE-2022-25927","record":{"aliases":["CLSA-2026-1782781179","DEBIAN-CVE-2022-25927","GHSA-fhg7-m89q-25r3","ROOT-APP-NPM-CVE-2022-25927","UBUNTU-CVE-2022-25927"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript user agent parser","requires_auth":"none","summary":"An attacker can cause a denial of service in applications using ua-parser-js by sending specially crafted user agent strings that trigger excessive CPU usage.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[{"product":"ua-parser-js","vendor":"ua-parser-js_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/E:P","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"Versions of the package ua-parser-js from 0.7.30 and before 0.7.33, from 0.8.1 and before 1.0.33 are vulnerable to Regular Expression Denial of Service (ReDoS) via the trim() function.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":"2023-02-01","github_poc":2,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-02-01T04:16:47Z","kind":"github_poc","ref":"https://github.com/masahiro331/cve-2022-25927","stars":0,"title":null},{"date":"2026-03-28T10:15:38Z","kind":"github_poc","ref":"https://github.com/Sleuth-in-town/CVE-2022-25927-test","stars":0,"title":null}],"tier":"weaponised"},"has_fix":true,"headline":"ReDoS Vulnerability in ua-parser-js version","id":"CVE-2022-25927","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":4,"n_references":2,"next":{"headline":"Cross-site Scripting (XSS)","id":"CVE-2022-25929"},"packages":[{"ecosystem":"npm","fixed":["0.7.33"],"introduced":["0.7.30"],"last_affected":[],"package":"ua-parser-js","purl":null,"source":"GHSA-fhg7-m89q-25r3"},{"ecosystem":"npm","fixed":["0.7.33"],"introduced":["0.7.30"],"last_affected":[],"package":"ua-parser-js","purl":"pkg:npm/ua-parser-js","source":"GHSA-fhg7-m89q-25r3"},{"ecosystem":"npm","fixed":["1.0.33"],"introduced":["0.8.0"],"last_affected":[],"package":"ua-parser-js","purl":null,"source":"GHSA-fhg7-m89q-25r3"},{"ecosystem":"npm","fixed":["1.0.33"],"introduced":["0.8.0"],"last_affected":[],"package":"ua-parser-js","purl":"pkg:npm/ua-parser-js","source":"GHSA-fhg7-m89q-25r3"}],"prev":{"headline":"window-control vulnerable to Command Injection due to improper input sanitization","id":"CVE-2022-25926"},"products":["ua-parser-js"],"published":"2023-01-25","related":[{"cvss_score":7.5,"headline":"Regular Expression Denial of Service (ReDoS) in ua-parser-js","id":"CVE-2021-27292","kev_date_added":null,"published":"2021-03-17"},{"cvss_score":5.3,"headline":"UAParser.js: Unbounded `Sec-CH-UA-Model` parsing can trigger ReDoS in `withClientHints()`","id":"CVE-2026-48125","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":5,"headline":"ua-parser-js Crypto Mining backdoor","id":"CVE-2021-4229","kev_date_added":null,"published":"2022-05-24"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-01","vendors":["n/a"]},"summary":"An attacker can cause a denial of service in applications using ua-parser-js by sending specially crafted user agent strings that trigger excessive CPU usage.","url":"https://insights.sbomify.com/CVE-2022-25927/"}
