Description
NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, the refresh-token cookie was set with httpOnly: true but missing both the secure flag and the sameSite attribute. Over plain HTTP the cookie could be intercepted on the network; without sameSite, browsers attached it to cross-site POSTs, enabling CSRF against the token-refresh endpoint. This vulnerability is fixed in 2026.04.1.
