CVE-2026-28383: Vulnerability in Grafana Grafana OSS
A request to the Grafana plugin resources endpoint can cause unbounded memory allocation by reading the entire request body into memory. An authenticated user can exploit this to trigger an out-of-memory condition, potentially causing a denial of service.
AI Analysis
Technical Summary
This vulnerability involves the Grafana OSS plugin resources endpoint reading the entire request body into memory without bounds. An authenticated attacker can exploit this behavior to trigger excessive memory consumption, potentially causing the application to run out of memory and become unavailable. The issue is classified under CWE-770 (Allocation of Resources Without Limits or Throttling). The CVSS v3.1 vector indicates network attack vector, low attack complexity, requires privileges, no user interaction, unchanged scope, no confidentiality or integrity impact, but high impact on availability.
Potential Impact
Exploitation of this vulnerability can cause denial of service by exhausting server memory resources. There is no impact on confidentiality or integrity. The attack requires an authenticated user, limiting exposure to authorized users only. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting access to the plugin resources endpoint to trusted users only and monitor resource usage to detect abnormal memory consumption.
