Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27879 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, 12.1.10, 12.2.8, 12.3.6, 12.4.2\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-2026-27879/ (Markdown: https://insights.sbomify.com/CVE-2026-27879/index.md)","id":"CVE-2026-27879","markdown":"https://insights.sbomify.com/CVE-2026-27879/index.md","name":"CVE-2026-27879","record":{"aliases":["BIT-grafana-2026-27879","GHSA-4368-7mjc-5763","MINI-2342-wmfc-g9c7","MINI-5xvw-w79h-mv24","MINI-68vj-5fgv-7975","MINI-6r65-mcc9-j5ph","MINI-7pf9-px9w-hjmf","MINI-7q5w-rhm5-9ffv","MINI-986c-jvv6-xxx2","MINI-9xw5-7pf8-qc32","MINI-f253-w2p4-6pj3","MINI-h672-qrw8-w2m4","MINI-jfpv-7mqp-vx9p","MINI-jg6f-7jr9-crh8","MINI-vrgc-xg33-gc7p","MINI-wcj8-mvgr-5rjh","MINI-x6gf-6x4p-xf62","MINI-xm8j-pxff-9p4v","UBUNTU-CVE-2026-27879"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Grafana monitoring platform","requires_auth":"low_privilege","summary":"Attackers can trigger out-of-memory crashes in Grafana by sending resample queries, causing a denial of service.","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-787","name":"Out-of-bounds Write"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A resample query can be used to trigger out-of-memory crashes in Grafana.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Query resampling can cause unbounded memory allocations","id":"CVE-2026-27879","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"grafana:grafana","products":["grafana:grafana"],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"OpenFeature evaluation API reads input data with no bounds","id":"CVE-2026-27880"},"packages":[{"ecosystem":"Bitnami","fixed":["11.6.14","12.1.10","12.2.8","12.3.6","12.4.2"],"introduced":["8.0.0","12.0.0","12.2.0","12.3.0","12.4.0"],"last_affected":[],"package":"grafana","purl":"pkg:bitnami/grafana","source":"BIT-grafana-2026-27879"}],"prev":{"headline":"Tempo TraceQL query with exemplar hint could result in unbounded memory usage","id":"CVE-2026-27878"},"products":["Grafana"],"published":"2026-03-27","related":[{"cvss_score":7.5,"headline":"Grafana Path Traversal","id":"CVE-2021-43798","kev_date_added":"2025-10-09","published":"2021-12-07"},{"cvss_score":10,"headline":"Incorrect privilege assignment","id":"CVE-2025-41115","kev_date_added":null,"published":"2025-11-21"},{"cvss_score":9.8,"headline":"Grafana vulnerable to race condition allowing privilege escalation","id":"CVE-2022-39328","kev_date_added":null,"published":"2022-11-08"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2022-28660","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2022-26148","kev_date_added":null,"published":"2022-03-21"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2018-15727","kev_date_added":null,"published":"2018-08-29"},{"cvss_score":9.4,"headline":"Grafana SQL Expressions allow for remote code execution","id":"CVE-2024-9264","kev_date_added":null,"published":"2024-10-18"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["Grafana"]},"summary":"Attackers can trigger out-of-memory crashes in Grafana by sending resample queries, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-27879/"}
