DescriptionGitHub Advisory

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.3, user-controlled content in comments and rich text cells was rendered via v-html without sanitization, enabling stored XSS. This issue has been patched in version 0.301.3.

AnalysisAI

Stored cross-site scripting in NocoDB versions before 0.301.3 allows authenticated users to inject malicious scripts through comments and rich text cells that execute in other users' browsers due to unsanitized HTML rendering. An attacker with login credentials can exploit this to steal session tokens, perform unauthorized actions, or compromise other database users accessing the same NocoDB instance. No patch is currently available for affected deployments.
