{"id":"CVE-2025-62517","aliases":["GHSA-xcg2-9pp4-j82x"],"url":"https://o3.security/vulnerability/CVE-2025-62517","summary":"Rollbar.js Prototype Pollution Vulnerability in merge()","details":"Rollbar.js offers error tracking and logging from Javascript to Rollbar. In versions before 2.26.5 and from 3.0.0-alpha1 to before 3.0.0-beta5, there is a prototype pollution vulnerability in merge(). If application code calls rollbar.configure() with untrusted input, prototype pollution is possible. This issue has been fixed in versions 2.26.5 and 3.0.0-beta5. A workaround involves ensuring that values passed to rollbar.configure() do not contain untrusted input.","published":"2025-10-23T19:52:15.376Z","modified":"2026-07-15T01:49:05.288199645Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"rollbar","fixedVersion":"2.26.5"},{"ecosystem":"npm","name":"rollbar","fixedVersion":"3.0.0-beta5"}],"fix":{"url":"https://github.com/rollbar/rollbar.js/commit/61032fe6c208b71e249514800808a54bcb8cb8bb","label":"rollbar/rollbar.js@61032fe"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/62xxx/CVE-2025-62517.json"},{"type":"ADVISORY","url":"https://github.com/rollbar/rollbar.js/security/advisories/GHSA-xcg2-9pp4-j82x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-62517"},{"type":"FIX","url":"https://github.com/rollbar/rollbar.js/commit/61032fe6c208b71e249514800808a54bcb8cb8bb"},{"type":"FIX","url":"https://github.com/rollbar/rollbar.js/commit/d717def8b68f4a947975d0aebb729869cdb2d343"},{"type":"FIX","url":"https://github.com/rollbar/rollbar.js/pull/1390"},{"type":"FIX","url":"https://github.com/rollbar/rollbar.js/pull/1394"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:05.288199645Z"}}
