Versions 6.5.1 through 12.1.1 have a Prototype pollution vulnerability. The vulnerability resides in line 94 of shared/utils.mjs, where the indexOf() function is used to check whether user provided input contain forbidden strings. Despite a previous fix that attempted to mitigate prototype pollution by checking whether user input contained a forbidden key, it is still possible to pollute Object.prototype via a crafted input using Array.prototype. The exploit works across Windows and Linux and on Node and Bun runtimes.  Any application that processes attacker-controlled input using this package may be affected  by the following: Authentication Bypass, Denial of Service and RCE. This issue is fixed in version 12.1.2.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-27212","reference_id":"","reference_type":"","scores":[{"value":"0.0011","scoring_system":"epss","scoring_elements":"0.29197","published_at":"2026-06-14T12:55:00Z"},{"value":"0.0011","scoring_system":"epss","scoring_elements":"0.2919","published_at":"2026-06-12T12:55:00Z"},{"value":"0.0011","scoring_system":"epss","scoring_elements":"0.29209","published_at":"2026-06-13T12:55:00Z"},{"value":"0.0011","scoring_system":"epss","scoring_elements":"0.28986","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-27212"},{"reference_url":"https://github.com/nolimits4web/swiper","reference_id":"","reference_type":"","scores":[{"value":"9.4","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/nolimits4web/swiper"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27212","reference_id":"CVE-2026-27212","reference_type":"","scores":[{"value":"9.4","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27212"},{"reference_url":"https://github.com/nolimits4web/swiper/commit/d3e663322a13043ca63aaba235d8cf3900e0c8cf","reference_id":"d3e663322a13043ca63aaba235d8cf3900e0c8cf","reference_type":"","scores":[{"value":"9.4","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-02-24T18:52:46Z/"}],"url":"https://github.com/nolimits4web/swiper/commit/d3e663322a13043ca63aaba235d8cf3900e0c8cf"},{"reference_url":"https://github.com/advisories/GHSA-hmx5-qpq5-p643","reference_id":"GHSA-hmx5-qpq5-p643","reference_type":"","scores":[{"value":"CRITICAL","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-hmx5-qpq5-p643"},{"reference_url":"https://github.com/nolimits4web/swiper/security/advisories/GHSA-hmx5-qpq5-p643","reference_id":"GHSA-hmx5-qpq5-p643","reference_type":"","scores":[{"value":"CRITICAL","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"9.4","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-02-24T18:52:46Z/"}],"url":"https://github.com/nolimits4web/swiper/security/advisories/GHSA-hmx5-qpq5-p643"},{"reference_url":"https://github.com/nolimits4web/swiper/releases/tag/v12.1.2","reference_id":"v12.1.2","reference_type":"","scores":[{"value":"9.4","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-02-24T18:52:46Z/"}],"url":"https://github.com/nolimits4web/swiper/releases/tag/v12.1.2"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/39441?format=json","purl":"pkg:npm/swiper@12.1.2","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/swiper@12.1.2"}],"aliases":["CVE-2026-27212","GHSA-hmx5-qpq5-p643"],"risk_score":4.5,"exploitability":"0.5","weighted_severity":"9.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-x6q6-ya3y-wqbm"}],"fixing_vulnerabilities":[],"risk_score":"4.5","resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/swiper@11.2.1"}
