Reading the vendor advisory
Black Shard's team can check your exposure to CVE-2026-126269 and take the fix off your plate.
NocoDB before 2026.09.0 contains a stored cross-site scripting vulnerability that allows authenticated Editor users to execute scripts by storing crafted attachment MIME types like text/html;image/png. Attackers can write the value through the records API so the /dltemp signed URL serves HTML inline, stealing session tokens from localStorage to impersonate victims.
Black Shard's team can check your exposure, take a fix off your plate or step in on a live incident.
