{"id":"CVE-2023-5654","aliases":[],"url":"https://o3.security/vulnerability/CVE-2023-5654","summary":"React Developer Tools extension Improper Authorization vulnerability","details":"The React Developer Tools extension registers a message listener with window.addEventListener('message', <listener>) in a content script that is accessible to any webpage that is active in the browser. Within the listener is code that requests a URL derived from the received message via fetch(). The URL is not validated or sanitised before it is fetched, thus allowing a malicious web page to arbitrarily fetch URL’s via the victim's browser.","published":"2023-10-19T15:31:08Z","modified":"2024-09-12T18:41:02Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"react-devtools-core","fixedVersion":"4.28.4"}],"fix":{"url":"https://github.com/facebook/react/pull/27417","label":"facebook/react#27417"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-5654"},{"type":"WEB","url":"https://github.com/facebook/react/pull/27417"},{"type":"WEB","url":"https://github.com/facebook/react/commit/09285d5a7f1c08bec09f44cec3d0518a603597fc"},{"type":"WEB","url":"https://github.com/facebook/react/commit/94d5b5b2bf5204ebd289a113989c0e2c51b626ef"},{"type":"WEB","url":"https://gist.github.com/CalumHutton/1fb89b64409570a43f89d1fd3274b231"},{"type":"PACKAGE","url":"https://github.com/facebook/react"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-09-12T18:41:02Z"}}
