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-2026-5189 in the wild and no public exploit code.\n\nAffected product: Sonatype Nexus Repository Manager. 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-2026-5189/ (Markdown: https://insights.sbomify.com/CVE-2026-5189/index.md)","id":"CVE-2026-5189","markdown":"https://insights.sbomify.com/CVE-2026-5189/index.md","name":"CVE-2026-5189","record":{"aliases":["GHSA-4gcp-x7jh-x4v7"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Nexus Repository Manager","requires_auth":"none","summary":"Unauthenticated attackers can exploit hardcoded credentials in the internal database to execute arbitrary commands and access data, requiring a specific non-default configuration.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Sonatype","cpe":[{"product":"nexus_repository_manager","vendor":"sonatype"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"CWE-798: Use of Hard-coded Credentials in Sonatype Nexus Repository Manager versions 3.0.0 through 3.70.5 allows an unauthenticated attacker with network access to gain unauthorized read/write access to the internal database and execute arbitrary OS commands as the Nexus process user.
