Grafana Drama: CISA’s Latest Vulnerability Headache!
The Grafana flaw, now part of CISA’s Known Exploited Vulnerabilities Catalog, is like leaving your front door open in a neighborhood full of opportunistic burglars. If you’re self-hosting Grafana, it’s time to update faster than a squirrel on espresso!

Hot Take:
Grafana, the open-source darling of server monitoring, has a new gig: starring in CISA’s latest episode of “Known Exploited Vulnerabilities”! Apparently, Grafana’s got a thing for directory traversal—who knew it had such wanderlust?—and CISA’s just trying to rain on its parade. Looks like it’s time for self-hosted Grafana users to hit the update button before their servers start spilling secrets like a chatty neighbor at a block party!
Key Points:
- CISA adds Grafana flaw CVE-2021-43798 to its Known Exploited Vulnerabilities catalog.
- The vulnerability is a directory traversal issue affecting specific Grafana versions, allowing unauthorized file access.
- Grafana Cloud instances are safe, but self-hosted users must update to patched versions.
- Federal agencies have until October 30, 2025, to fix the vulnerability as per CISA’s directive.
- Private organizations are also encouraged to review and address vulnerabilities in the catalog.
