Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33374 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- grafana (Bitnami): affected from 12.0.0; fixed in 12.4.13, 13.0.11, 13.1.8, 13.2.4\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-2026-33374/ (Markdown: https://insights.sbomify.com/CVE-2026-33374/index.md)","id":"CVE-2026-33374","markdown":"https://insights.sbomify.com/CVE-2026-33374/index.md","name":"CVE-2026-33374","record":{"aliases":["BIT-grafana-2026-33374","GHSA-5mj5-pfmr-wxjp","UBUNTU-CVE-2026-33374"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Grafana monitoring platform","requires_auth":"low_privilege","summary":"Authenticated users can crash Grafana servers by sending large payloads to the Prometheus rule conversion API due to missing size limits.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GRAFANA","cpe":[],"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-789","name":"Memory Allocation with Excessive Size Value"},{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The Prometheus rule conversion API endpoints in Grafana do not limit request body size, allowing authenticated users to trigger unbounded memory allocations that can crash the server through out-of-memory conditions.","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":"Unbounded memory allocation in the Prometheus rule conversion API","id":"CVE-2026-33374","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Grafana MSSQL Data Source Plugin: Restriction Bypass Leading to OOM DoS","id":"CVE-2026-33375"},"packages":[{"ecosystem":"Bitnami","fixed":["12.4.13","13.0.11","13.1.8","13.2.4"],"introduced":["12.0.0","13.0.0","13.1.0","13.2.0"],"last_affected":[],"package":"grafana","purl":"pkg:bitnami/grafana","source":"BIT-grafana-2026-33374"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2026-33373"},"products":["Grafana Enterprise","Grafana OSS"],"published":"2026-10-13","related":[],"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":"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":"2026-10-13","vendors":["Grafana"]},"summary":"Authenticated users can crash Grafana servers by sending large payloads to the Prometheus rule conversion API due to missing size limits.","url":"https://insights.sbomify.com/CVE-2026-33374/"}
