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-2026-79993 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- zookeeper (Bitnami): affected from 3.8.0; fixed in 3.8.7, 3.9.6\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-2026-79993/ (Markdown: https://insights.sbomify.com/CVE-2026-79993/index.md)","id":"CVE-2026-79993","markdown":"https://insights.sbomify.com/CVE-2026-79993/index.md","name":"CVE-2026-79993","record":{"aliases":["BIT-zookeeper-2026-79993","CLEANSTART-2026-GJ18736","CLEANSTART-2026-VL27493","CLEANSTART-2026-VR96593","CLEANSTART-2026-ZO47160","DEBIAN-CVE-2026-79993","GHSA-9x9g-5r48-3wvg","MINI-835h-854j-wh9h","MINI-qj34-rr98-fvmm","UBUNTU-CVE-2026-79993"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Distributed coordination service","requires_auth":"none","summary":"An unauthenticated attacker can delete any empty persistent znode in Apache ZooKeeper by bypassing ACL checks on the deleteContainer opcode.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"zookeeper","vendor":"apache"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The `deleteContainer` opcode (0x14/20) is processed without verifying the caller's ACL permissions, allowing any authenticated client to delete specific znodes in the data tree regardless of the ACL restrictions on the znode or its parent.
