Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-78593 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kibana (Bitnami): affected from 8.0.0; fixed in 8.19.21, 9.4.6, 9.5.3\n- elk (Bitnami): affected from 8.0.0; fixed in 8.19.21, 9.4.6, 9.5.3\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-2026-78593/ (Markdown: https://insights.sbomify.com/CVE-2026-78593/index.md)","id":"CVE-2026-78593","markdown":"https://insights.sbomify.com/CVE-2026-78593/index.md","name":"CVE-2026-78593","record":{"aliases":["BIT-elk-2026-78593","BIT-kibana-2026-78593","GHSA-6q7w-4cg4-7827","MINI-27jh-hmf8-f3w8","MINI-c9hh-663q-rf9g","MINI-mvc5-hgcp-xj33","MINI-mxwm-mcf7-wpxg","MINI-rghj-fq3x-749q","MINI-x4gw-f2pq-34vw","MINI-xgmj-j85f-7hpg","MINI-xjgc-rcp2-7hx6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Kibana data visualization","requires_auth":"low_privilege","summary":"Authenticated users with Fleet privileges can inject code into server-side templates to modify Elasticsearch pipelines beyond their authorized permissions.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"elastic","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"An insufficiently validated configuration field in Kibana's Cribl integration allows an authenticated user holding Kibana Fleet management privileges to inject attacker-controlled expressions into a server-side script template, resulting in an Elasticsearch ingest pipeline being written beyond the caller's authorized Elasticsearch permissions.","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":"Improper Control of Generation of Code in Kibana Leading to Privilege Escalation","id":"CVE-2026-78593","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Improper Handling of Highly Compressed Data in APM Server Leading to Persistent Denial of Service","id":"CVE-2026-78594"},"packages":[{"ecosystem":"Bitnami","fixed":["8.19.21","9.4.6","9.5.3"],"introduced":["8.0.0","9.0.0","9.5.0"],"last_affected":[],"package":"elk","purl":"pkg:bitnami/elk","source":"BIT-elk-2026-78593"},{"ecosystem":"Bitnami","fixed":["8.19.21","9.4.6","9.5.3"],"introduced":["8.0.0","9.0.0","9.5.0"],"last_affected":[],"package":"kibana","purl":"pkg:bitnami/kibana","source":"BIT-kibana-2026-78593"}],"prev":{"headline":"Path traversal in Kibana","id":"CVE-2026-78592"},"products":["Kibana"],"published":"2026-09-03","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":"2026-09-03","vendors":["Elastic"]},"summary":"Authenticated users with Fleet privileges can inject code into server-side templates to modify Elasticsearch pipelines beyond their authorized permissions.","url":"https://insights.sbomify.com/CVE-2026-78593/"}
