{"id":"CVE-2023-45311","aliases":["GHSA-8r6j-v8pm-fqw3"],"url":"https://o3.security/vulnerability/CVE-2023-45311","summary":"Code injection in fsevents","details":"fsevents before 1.2.11 depends on the https://fsevents-binaries.s3-us-west-2.amazonaws.com URL, which might allow an adversary to execute arbitrary code if any JavaScript project (that depends on fsevents) distributes code that was obtained from that URL at a time when it was controlled by an adversary. NOTE: some sources feel that this means that no version is affected any longer, because the URL is not controlled by an adversary.","published":"2023-10-06T00:00:00Z","modified":"2026-07-15T01:48:52.785531380Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":6,"affectedPackages":[{"ecosystem":"npm","name":"fsevents","fixedVersion":"1.2.11"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/atlassian/moo/blob/56ccbdd41b493332bc2cd7a4097a5802594cdb9c/package-lock.json#L1901-L1902"},{"type":"WEB","url":"https://github.com/atlassian/react-immutable-proptypes/blob/ddb9fa5194b931bf7528eb4f2c0a8c3434f70edd/package-lock.json#L153"},{"type":"WEB","url":"https://github.com/cloudflare/authr/blob/3f6129d97d06e61033a7f237d84e35e678db490f/ts/package-lock.json#L1512"},{"type":"WEB","url":"https://github.com/cloudflare/hugo-cloudflare-docs/blob/e0f7cfa195af8ef1bfa51a487be7d34ba298ed06/package-lock.json#L494"},{"type":"WEB","url":"https://github.com/cloudflare/redux-grim/blob/b652f99f95fb16812336073951adc5c5a93e2c23/package-lock.json#L266-L267"},{"type":"WEB","url":"https://github.com/cloudflare/serverless-cloudflare-workers/blob/e95e1e9c9770ed9a3d9480c1fa73e64391268354/package-lock.json#L737"},{"type":"WEB","url":"https://github.com/fsevents/fsevents/compare/v1.2.10...v1.2.11"},{"type":"WEB","url":"https://security.snyk.io/vuln/SNYK-JS-FSEVENTS-5487987"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45311.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45311"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:52.785531380Z"}}
