{"id":"CVE-2021-35440","details":"Smashing 1.3.4 is vulnerable to Cross Site Scripting (XSS). A URL for a widget can be crafted and used to execute JavaScript on the victim's computer. The JavaScript code can then steal data available in the session/cookies depending on the user environment (e.g. if re-using internal URL's for deploying, or cookies that are very permissive) private information may be retrieved by the attacker.","aliases":["GHSA-254j-mmc5-qhpx"],"modified":"2026-07-09T01:25:36.527462Z","published":"2021-07-06T15:15:07.757Z","references":[{"type":"ADVISORY","url":"https://github.com/Smashing/smashing/blob/ad7325f159f89854ca4e7d94e7be9bee507b6d46/CHANGELOG.md"},{"type":"FIX","url":"https://github.com/Smashing/smashing/pull/186"},{"type":"FIX","url":"https://github.com/Smashing/smashing/pull/186#issuecomment-871727614"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/smashing/smashing","events":[{"introduced":"5f472645fd69cd395cf2fa0befc4e8e0d673d3be"},{"last_affected":"5f472645fd69cd395cf2fa0befc4e8e0d673d3be"}],"database_specific":{"cpe":"cpe:2.3:a:smashing_project:smashing:1.3.4:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.3.4"},{"last_affected":"1.3.4"}],"source":"CPE_STRING"}}],"versions":["1.3.4","v.1.3.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-35440.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
