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.
AnalysisAI
Unbounded memory allocation in Grafana OSS's plugin resources endpoint allows any authenticated low-privileged user to trigger an out-of-memory condition by sending a sufficiently large HTTP request body, resulting in denial of service against the Grafana instance. Affected versions span a wide range from 6.7.0 through 13.0.1, with vendor-released security patches available across all supported branches. No public exploit exists and CISA has not added this to the KEV catalog; the EPSS score of 0.04% (12th percentile) reflects very low observed exploitation probability.
Technical ContextAI
The vulnerability is rooted in CWE-770 (Allocation of Resources Without Limits or Throttling). Grafana's plugin architecture exposes HTTP sub-routes through the plugin resources endpoint, which plugins use to serve data and UI assets. The flaw occurs when the Grafana backend reads the entirety of an incoming HTTP request body into memory without enforcing a size cap or streaming the data, meaning a single large request can exhaust available heap space. The affected product is identified by CPE cpe:2.3:a:grafana:grafana_oss:*:*:*:*:*:*:*:* spanning versions 6.7.0 through 13.0.1. The CVSS vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H precisely captures the profile: network-reachable, low complexity, low-privilege authentication required, no confidentiality or integrity impact, and complete availability impact on the affected component.
RemediationAI
The primary remediation is to upgrade to the appropriate vendor-released security patch for your installed branch: 11.6.14+security-04 for the 11.x line, 12.2.8+security-04 for the 12.2.x line, 12.3.6+security-04 for the 12.3.x line, 12.4.3+security-02 for the 12.4.x line, or 13.0.1+security-01 for the 13.x line. Full advisory details are at https://grafana.com/security/security-advisories/cve-2026-28383. If immediate patching is not feasible, compensating controls include placing a reverse proxy (such as nginx or HAProxy) in front of Grafana configured with a client request body size limit (e.g., nginx's client_max_body_size directive), which will reject oversized requests before they reach the Grafana process - note this may affect legitimate large plugin payloads and should be sized appropriately for your environment. Additionally, restricting plugin resource endpoint access to known-trusted users via Grafana's RBAC controls reduces the pool of accounts that can trigger this condition, at the cost of reduced plugin functionality for broader user tiers.
