An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-10748 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-2026-10748/ (Markdown: https://insights.sbomify.com/CVE-2026-10748/index.md)","id":"CVE-2026-10748","markdown":"https://insights.sbomify.com/CVE-2026-10748/index.md","name":"CVE-2026-10748","record":{"aliases":["GHSA-mfx4-8g7q-p97w"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Nexus Repository","requires_auth":"high_privilege","summary":"Authenticated users with licensing privileges can execute arbitrary OS commands via crafted license files in Nexus Repository.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Sonatype","cpe":[{"product":"nexus_repository_manager","vendor":"sonatype"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"An authenticated user with the nx-licensing-create privilege can upload a specially crafted license file to execute arbitrary operating system commands as the Nexus process user in Sonatype Nexus Repository 3 versions before 3.92.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Nexus Repository 3 - Remote Code Execution via License Deserialization","id":"CVE-2026-10748","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sonatype:nexus_repository_manager","products":["sonatype:nexus_repository_manager"],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Post Duplicator \u003c 3.0.15 - Contributor+ PHP Object Injection via customMetaData","id":"CVE-2026-10749"},"packages":[],"prev":{"headline":"IBM MQ Appliance is affected by a heap buffer overflow vulnerability in protocol message processing","id":"CVE-2026-10747"},"products":["Nexus Repository"],"published":"2026-06-16","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":9.4,"headline":"Nexus Repository 3 - Authenticated Remote Code Execution via Task Property Injection","id":"CVE-2026-3199","kev_date_added":null,"published":"2026-04-08"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-17","vendors":["Sonatype"]},"summary":"Authenticated users with licensing privileges can execute arbitrary OS commands via crafted license files in Nexus Repository.","url":"https://insights.sbomify.com/CVE-2026-10748/"}
