An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33376 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- grafana (Bitnami): affected from 9.4.0; 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-2026-33376/ (Markdown: https://insights.sbomify.com/CVE-2026-33376/index.md)","id":"CVE-2026-33376","markdown":"https://insights.sbomify.com/CVE-2026-33376/index.md","name":"CVE-2026-33376","record":{"aliases":["BIT-grafana-2026-33376","GHSA-3r2p-7499-27q3","MINI-28m3-5v2q-6qrw","MINI-3r52-84rf-gfm8","MINI-4jj3-5q44-59m8","MINI-6w92-m35j-w97p","MINI-8g72-c866-6qhr","MINI-8x8q-xprw-mr72","MINI-966j-w9w6-4m2x","MINI-gcjx-875q-gpmf","MINI-h27q-q64w-mmwg","MINI-jmcx-hhxc-h8rx","MINI-jv8x-xqf2-f984","MINI-jxr2-66jf-xr33","MINI-pc3q-gfxc-pwcv","MINI-v47x-9gwx-6p27","MINI-vgqj-56p7-8wxr","MINI-xvpc-mm96-cpgf","UBUNTU-CVE-2026-33376"],"analysis":{"component_type":"web_application","fix_type":"configuration_change","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Grafana OSS","requires_auth":"none","summary":"Attackers can bypass IPv6 allow-list restrictions in Grafana's Auth Proxy feature due to incorrect default subnet masking, requiring manual configuration updates.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GRAFANA","cpe":[{"product":"grafana","vendor":"grafana"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"When using an IPv6 allow-list for the Auth Proxy feature, it defaults to /32 addresses.
