CVE-2026-102589
Last modified
CVE-2026-102589 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. When independent Grafana instances share the same [rendering] renderer_token, an image renderer key issued by one instance is accepted by the others, so a user on one instance could act as the user with the same ID on another (origin validation error). This affects instances with the renderAuthJWT feature toggle enabled, the default from Grafana 13.0.0.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
