An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19843 in the wild and no public exploit code.\n\nAffected product: Red Hat Directory Server 11. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-19843/ (Markdown: https://insights.sbomify.com/CVE-2026-19843/index.md)","id":"CVE-2026-19843","markdown":"https://insights.sbomify.com/CVE-2026-19843/index.md","name":"CVE-2026-19843","record":{"aliases":["AZL-99986","DEBIAN-CVE-2026-19843","GHSA-p34m-7cj2-q64p","RHSA-2026:64768","RHSA-2026:64769","RHSA-2026:64782","RHSA-2026:65375","UBUNTU-CVE-2026-19843"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"389 Directory Server","requires_auth":"high_privilege","summary":"An attacker with delegated privileges can inject shell commands via a malicious LDAP DN, leading to root code execution when an admin views the entry in the Cockpit console.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A flaw was found in 389-ds-base.
