{"id":"CVE-2024-45613","summary":"CKEditor 5 has Cross-site Scripting vulnerability in the clipboard package","details":"CKEditor 5 is a JavaScript rich-text editor. Starting in version 40.0.0 and prior to version 43.1.1, a Cross-Site Scripting (XSS) vulnerability is present in the CKEditor 5 clipboard package. This vulnerability could be triggered by a specific user action, leading to unauthorized JavaScript code execution, if the attacker managed to insert a malicious content into the editor, which might happen with a very specific editor configuration. This vulnerability only affects installations where the Block Toolbar plugin is enabled and either the General HTML Support (with a configuration that permits unsafe markup) or the HTML Embed plugin is also enabled. A fix for the problem is available in version 43.1.1. As a workaround, one may disable the block toolbar plugin.","aliases":["GHSA-rgg8-g5x8-wr9v"],"modified":"2026-08-12T03:51:11.326996180Z","published":"2024-09-25T13:27:03.546Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/45xxx/CVE-2024-45613.json"},"references":[{"type":"WEB","url":"https://github.com/ckeditor/ckeditor5/releases/tag/v43.1.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/45xxx/CVE-2024-45613.json"},{"type":"ADVISORY","url":"https://github.com/ckeditor/ckeditor5/security/advisories/GHSA-rgg8-g5x8-wr9v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-45613"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ckeditor/ckeditor5","events":[{"introduced":"2a9b1de93d395bdf8d137a4d875a6b21129fa68a"},{"fixed":"6b1e550ba3eee4618f36258ee2ed7cbbc2361246"}],"database_specific":{"cpe":"cpe:2.3:a:ckeditor:ckeditor5:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"40.0.0"},{"fixed":"43.1.1"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-45613.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}]}
