What is CVE-2026-46550?
CVE-2026-46550 is a medium-severity vulnerability in nocodb, published on 23 Jun 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-614
