CVE-2023-49781Public exploitNetwork attack vector

Credential theft via unsanitized formula comments

Published May 13, 2024 · Updated Aug 2, 2024

Stored XSS in NocoDB before 0.202.9 allows remote authenticated users to steal a victim's session token through a shared table link. Formula.vue passes replaceUrlsWithLink() output to v-html; the helper converts URI::(...) into links but leaves surrounding attacker-controlled HTML unencoded. Exploitation requires an authenticated attacker to create and share a malicious formula-backed table and a victim to open its public link.
