Answer in brief
CVE-2026-102589 records a High severity (CVSS 7.1) vulnerability in Cross-instance user impersonation through image renderer JWTs. The current sources do not mark it as known exploited. The current feed maps Grafana/Grafana Enterprise (generic), Grafana/Grafana OSS (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
