Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-44963 in the wild and no public exploit code.\n\nAffected product: Veeam Backup and Replication. 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-2026-44963/ (Markdown: https://insights.sbomify.com/CVE-2026-44963/index.md)","id":"CVE-2026-44963","markdown":"https://insights.sbomify.com/CVE-2026-44963/index.md","name":"CVE-2026-44963","record":{"aliases":["GHSA-qgvw-vfmj-prrg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Backup and Replication","requires_auth":"low_privilege","summary":"An authenticated domain user can achieve remote code execution on the Veeam Backup Server via a deserialization vulnerability.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"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:H","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"A vulnerability allowing remote code execution (RCE) on the Backup Server by an authenticated domain user.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-10","github_poc":2,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-18T05:58:58Z","kind":"github_poc","ref":"https://github.com/jockerjml/CVE-2026-44963-veeam-checker","stars":1,"title":"Detection scripts, patch checker \u0026 hardening guide for CVE-2026-44963 (Veeam B\u0026R RCE)"},{"date":"2026-06-10T01:16:26Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2026-44963","stars":0,"title":"CVE-2026-44963 - Draft - Veeam"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Deserialization in Backup and Replication","id":"CVE-2026-44963","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Android App","id":"CVE-2026-44964"},"packages":[],"prev":{"headline":"Code injection in Plesk","id":"CVE-2026-44962"},"products":["Backup and Replication"],"published":"2026-06-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-06-10","vendors":["Veeam"]},"summary":"An authenticated domain user can achieve remote code execution on the Veeam Backup Server via a deserialization vulnerability.","url":"https://insights.sbomify.com/CVE-2026-44963/"}
