{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/44263?format=json","vulnerability_id":"VCID-5rba-b2bd-nfgv","summary":"ReDoS Vulnerability in ua-parser-js version\n### Description:\nA regular expression denial of service (ReDoS) vulnerability has been discovered in `ua-parser-js`.\n\n### Impact:\nThis vulnerability bypass the library's `MAX_LENGTH` input limit prevention. By crafting a very-very-long user-agent string with specific pattern, an attacker can turn the script to get stuck processing for a very long time which results in a denial of service (DoS) condition.\n\n### Affected Versions:\nFrom version `0.7.30` to before versions `0.7.33` / `1.0.33`.\n\n### Patches:\nA patch has been released to remove the vulnerable regular expression, update to version `0.7.33` / `1.0.33` or later.\n\n### References:\n[Regular expression Denial of Service - ReDoS](https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS)\n\n### Credits:\nThanks to @Snyk who first reported the issue.","aliases":[{"alias":"CVE-2022-25927"},{"alias":"GHSA-fhg7-m89q-25r3"},{"alias":"GMS-2023-120"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/119172?format=json","purl":"pkg:deb/debian/node-ua-parser-js@0.8.1%2Bds%2B~0.7.36-3?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/node-ua-parser-js@0.8.1%252Bds%252B~0.7.36-3%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/63684?format=json","purl":"pkg:npm/ua-parser-js@0.7.33","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/ua-parser-js@0.7.33"},{"url":"http://public2.vulnerablecode.io/api/packages/63685?format=json","purl":"pkg:npm/ua-parser-js@1.0.33","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/ua-parser-js@1.0.33"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/119174?format=json","purl":"pkg:deb/debian/node-ua-parser-js@0.7.24%2Bds-1?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-5rba-b2bd-nfgv"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/node-ua-parser-js@0.7.24%252Bds-1%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/59375?format=json","purl":"pkg:npm/ua-parser-js@0.7.30","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-5rba-b2bd-nfgv"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/ua-parser-js@0.7.30"},{"url":"http://public2.vulnerablecode.io/api/packages/59373?format=json","purl":"pkg:npm/ua-parser-js@0.8.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-5rba-b2bd-nfgv"},{"vulnerability":"VCID-f6e7-4dxm-cug5"},{"vulnerability":"VCID-uqy7-83dp-37gd"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/ua-parser-js@0.8.0"}],"references":[{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2022-25927.json","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2022-25927.json"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2022-25927","reference_id":"","reference_type":"","scores":[{"value":"0.01453","scoring_system":"epss","scoring_elements":"0.81145","published_at":"2026-06-04T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2022-25927"},{"reference_url":"https://github.com/faisalman/ua-parser-js","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/faisalman/ua-parser-js"},{"reference_url":"https://github.com/faisalman/ua-parser-js/commit/a6140a17dd0300a35cfc9cff999545f267889411","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/faisalman/ua-parser-js/commit/a6140a17dd0300a35cfc9cff999545f267889411"},{"reference_url":"https://security.snyk.io/vuln/SNYK-JS-UAPARSERJS-3244450","reference_id":"","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://security.snyk.io/vuln/SNYK-JS-UAPARSERJS-3244450"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2165020","reference_id":"2165020","reference_type":"","scores":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2165020"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2022-25927","reference_id":"CVE-2022-25927","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-25927"},{"reference_url":"https://github.com/advisories/GHSA-fhg7-m89q-25r3","reference_id":"GHSA-fhg7-m89q-25r3","reference_type":"","scores":[],"url":"https://github.com/advisories/GHSA-fhg7-m89q-25r3"},{"reference_url":"https://github.com/faisalman/ua-parser-js/security/advisories/GHSA-fhg7-m89q-25r3","reference_id":"GHSA-fhg7-m89q-25r3","reference_type":"","scores":[{"value":"7.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/faisalman/ua-parser-js/security/advisories/
