CVE-2026-46550 nocodb CVE debrief

CVE-2026-46550 is a medium-severity vulnerability in NocoDB, a software for building databases as spreadsheets. The vulnerability involves the refresh-token cookie, which was set with httpOnly: true but missing both the secure flag and the sameSite attribute. This omission allows the cookie to be intercepted on the network over plain HTTP and attached to cross-site POSTs, enabling CSRF against the token-refresh endpoint. The vulnerability was fixed in version 2026.04.1. Users of affected versions should update to 2026.04.1 or later to mitigate this vulnerability. It is recommended that defenders review their inventory of NocoDB instances and ensure they are running the patched version.
