Grafana recently addressed a zero-day vulnerability, CVE-2021-43798, which allowed directory traversal attacks on Grafana software, urging users to promptly upgrade their Grafana 8.x instances. This vulnerability was discovered by researcher Jordy Versmissen, and despite initial timeline changes due to an AWS outage, an emergency release plan was executed to mitigate the threat. The blog post highlights the importance of transparent and blameless postmortems to learn from mistakes and improve future responses. Grafana Labs plans to introduce a bug bounty program to reward researchers and prevent them from submitting vulnerabilities to third parties, aiming to enhance their security protocols and streamline the release process for future incidents.
