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.","state":0,"publishedAt":"2025-10-23T19:52:15.376+00:00","modifiedAt":"2025-10-23T20:16:08.104+00:00","affected":[{"ecosystem":"Vendor product","name":"rollbar.js","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"rollbar\",\n                    \"product\": \"rollbar.js\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.26.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0-alpha1, < 3.0.0-beta5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/rollbar/rollbar.js/security/advisories/GHSA-xcg2-9pp4-j82x","https://github.com/rollbar/rollbar.js/pull/1390","https://github.com/rollbar/rollbar.js/pull/1394","https://github.com/rollbar/rollbar.js/commit/61032fe6c208b71e249514800808a54bcb8cb8bb","https://github.com/rollbar/rollbar.js/commit/d717def8b68f4a947975d0aebb729869cdb2d343"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-62517","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-62517","identifiers":["CVE-2025-62517"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
