Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3199 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-2026-3199/ (Markdown: https://insights.sbomify.com/CVE-2026-3199/index.md)","id":"CVE-2026-3199","markdown":"https://insights.sbomify.com/CVE-2026-3199/index.md","name":"CVE-2026-3199","record":{"aliases":["GHSA-w2wq-7mq5-mvww"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nexus Repository","requires_auth":"low_privilege","summary":"Authenticated attackers with task creation permissions can execute arbitrary code in Sonatype Nexus Repository by bypassing script creation controls.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Sonatype","cpe":[{"product":"nexus_repository_manager","vendor":"sonatype"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"A vulnerability in the task management component of Sonatype Nexus Repository versions 3.22.1 through 3.90.2 allows an authenticated attacker with task creation permissions to execute arbitrary code, bypassing the nexus.scripts.allowCreation security control.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Nexus Repository 3 - Authenticated Remote Code Execution via Task Property Injection","id":"CVE-2026-3199","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sonatype:nexus_repository_manager","products":["sonatype:nexus_repository_manager"],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"z-9527 admin user.js getUsers sql injection","id":"CVE-2026-3200"},"packages":[],"prev":{"headline":"Improper Access Control in mlflow/mlflow","id":"CVE-2026-3198"},"products":["Nexus Repository"],"published":"2026-04-08","related":[{"cvss_score":9.8,"headline":"Sonatype Nexus Repository Manager Incorrect Access Control","id":"CVE-2019-7238","kev_date_added":"2021-12-10","published":"2019-03-21"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2019-9629","kev_date_added":null,"published":"2019-07-08"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2017-17717","kev_date_added":null,"published":"2017-12-17"},{"cvss_score":9.2,"headline":"Nexus Repository 3 - Hardcoded Credential in Internal Database Component","id":"CVE-2026-5189","kev_date_added":null,"published":"2026-04-15"},{"cvss_score":8.9,"headline":"Nexus Repository 3 - Wildcard Privilege Update Self-Escalation to Administrator","id":"CVE-2026-17601","kev_date_added":null,"published":"2026-08-07"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2020-15871","kev_date_added":null,"published":"2020-07-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-09","vendors":["Sonatype"]},"summary":"Authenticated attackers with task creation permissions can execute arbitrary code in Sonatype Nexus Repository by bypassing script creation controls.","url":"https://insights.sbomify.com/CVE-2026-3199/"}
