{"id":"CVE-2026-27126","state":"PUBLISHED","title":"Craft CMS has Stored XSS in Table Field via \"HTML\" Column Type","description":"Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through 5.8.22, a stored Cross-site Scripting (XSS) vulnerability exists in the `editableTable.twig` component when using the `html` column type. The application fails to sanitize the input, allowing an attacker to execute arbitrary JavaScript when another user views a page with the malicious table field. In order to exploit the vulnerability, an attacker must have an administrator account, and `allowAdminChanges` must be enabled in production, which is against Craft's security recommendations. Versions 4.16.19 and 5.8.23 patch the issue.","publishedAt":"2026-02-24T02:30:04.882Z","updatedAt":"2026-02-24T19:35:38.348Z","severity":{"score":5.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["craftcms cms"],"affected":[{"vendor":"craftcms","product":"cms","versions":[{"version":">= 4.5.0-RC1, < 4.16.19","status":"affected"},{"version":">= 5.0.0-RC1, < 5.8.23","status":"affected"}]}],"references":["https://github.com/craftcms/cms/security/advisories/GHSA-3jh3-prx3-w6wc","https://github.com/craftcms/cms/commit/f5d488d9bb6eff7670ed2c2fe30e15692e92c52b"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27126.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27126","state":"PUBLISHED","datePublished":"2026-02-24T02:30:04.882Z","dateUpdated":"2026-02-24T19:35:38.348Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-17T18:42:27.043Z"},"containers":{"cna":{"title":"Craft CMS has Stored XSS in Table Field via \"HTML\" Column Type","descriptions":[{"lang":"en","value":"Craft is a content management system (CMS).
