Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33378 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- grafana (Bitnami): affected from 8.0.0; fixed in 11.6.14, 12.2.8, 12.3.6, 12.4.3, 13.0.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-33378/ (Markdown: https://insights.sbomify.com/CVE-2026-33378/index.md)","id":"CVE-2026-33378","markdown":"https://insights.sbomify.com/CVE-2026-33378/index.md","name":"CVE-2026-33378","record":{"aliases":["BIT-grafana-2026-33378","CLSA-2026-1780478536","GHSA-rr8q-qwrv-9pf6","MINI-26f5-c2v7-qjx9","MINI-2qx3-c8hm-h69p","MINI-76rh-4cmv-chpp","MINI-8rcv-mr9v-vmmr","MINI-9mh6-ggm4-c45v","MINI-g3vp-p34g-43jm","MINI-hf6r-wrxp-rgc4","MINI-jcg3-6xgm-vghm","MINI-jxxq-cm5p-rx6c","MINI-mqmr-7mjh-cmcp","MINI-pqjq-wjh7-798w","MINI-pw84-qrfx-3rmx","MINI-qp8c-gfjp-c2mw","MINI-rqvx-x9hg-693x","MINI-rx3m-q9xv-q6cg","MINI-xqff-cc2m-g5m2","UBUNTU-CVE-2026-33378"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Grafana OSS","requires_auth":"low_privilege","summary":"Attackers can cause an out-of-memory crash in Grafana by injecting negative intervals into the timeGroup macro, requiring a SQL datasource.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GRAFANA","cpe":[{"product":"grafana","vendor":"grafana"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Using the $__timeGroup macro, one can achieve an OOM by overloading the server.
