NocoDB: Stored Cross-Site Scripting via Rich Text Field

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • Fixed version: nocodb nocodb 0.301.3.

Low priority for now. Upgrade to nocodb nocodb 0.301.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.3, an authenticated user with Editor role can inject arbitrary HTML into Rich Text cells by bypassing the TipTap editor and sending raw HTML via the API. This issue has been patched in version 0.301.3.
