7.1 highCVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:LCVE-2026-102589 Cross-instance user impersonation through image renderer JWTs
High (7.1) in grafana. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
On this page
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.

Explain CVE-2026-102589 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-102589?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-102589?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-102589 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
