An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-25963 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/fleetdm/fleet/v4 (Go): affected all versions; fixed in 4.80.1\n- github.com/fleetdm/fleet/v4 (Go): affected all versions; fixed in 4.80.1\n- github.com/fleetdm/fleet/v4 (Go): affected all versions; fixed in 4.80.1\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-2026-25963/ (Markdown: https://insights.sbomify.com/CVE-2026-25963/index.md)","id":"CVE-2026-25963","markdown":"https://insights.sbomify.com/CVE-2026-25963/index.md","name":"CVE-2026-25963","record":{"aliases":["GHSA-5jvp-m9h4-253h","GO-2026-4561"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Fleet device management","requires_auth":"high_privilege","summary":"A team administrator can delete certificate templates belonging to other teams due to a missing ownership check, disrupting device enrollment and authentication workflows.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fleet","vendor":"fleetdm"}],"cvss":{"score":1.2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Fleet is open source device management software. In versions prior to 4.80.1, a broken authorization check in Fleet’s certificate template deletion API could allow a team administrator to delete certificate templates belonging to other teams within the same Fleet instance. Fleet supports certificate templates that are scoped to individual teams. In affected versions, the batch deletion endpoint validated authorization using a user-supplied team identifier but did not verify that the certificate template IDs being deleted actually belonged to that team. As a result, a team administrator could delete certificate templates associated with other teams, potentially disrupting certificate-based workflows such as device enrollment, Wi-Fi authentication, VPN access, or other certificate-dependent configurations for the affected teams. This issue does not allow privilege escalation, access to sensitive data, or compromise of Fleet’s control plane. Impact is limited to integrity and availability of certificate templates across teams. Version 4.80.1 patches the issue. If an immediate upgrade is not possible, administrators should restrict access to certificate template management to trusted users and avoid delegating team administrator permissions where not strictly required.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Fleet: Authorization Bypass in certificate template batch deletion for team administrators","id":"CVE-2026-25963","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Tandoor Recipes Affected by Authenticated Local File Disclosure (LFD) via Recipe Import leads to Arbitrary File Read","id":"CVE-2026-25964"},"packages":[{"ecosystem":"Go","fixed":["4.80.1"],"introduced":["0"],"last_affected":[],"package":"github.com/fleetdm/fleet/v4","purl":null,"source":"GHSA-5jvp-m9h4-253h"},{"ecosystem":"Go","fixed":["4.80.1"],"introduced":["0"],"last_affected":[],"package":"github.com/fleetdm/fleet/v4","purl":"pkg:golang/github.com/fleetdm/fleet/v4","source":"GHSA-5jvp-m9h4-253h"},{"ecosystem":"Go","fixed":["4.80.1"],"introduced":["0"],"last_affected":[],"package":"github.com/fleetdm/fleet/v4","purl":"pkg:golang/github.com/fleetdm/fleet/v4","source":"GO-2026-4561"}],"prev":{"headline":"MarkUs: Zip bomb in config upload enables DoS","id":"CVE-2026-25962"},"products":["fleet"],"published":"2026-02-26","related":[{"cvss_score":10,"headline":"SAML authentication vulnerability in Fleet","id":"CVE-2020-26276","kev_date_added":null,"published":"2020-12-17"},{"cvss_score":9.3,"headline":"Fleet before 4.87.0 Authentication Bypass via Device Identifiers","id":"CVE-2026-103264","kev_date_added":null,"published":"2026-10-01"},{"cvss_score":9.3,"headline":"Fleet has a JWT signature bypass vulnerability in Azure AD MDM enrollment","id":"CVE-2026-23518","kev_date_added":null,"published":"2026-01-21"},{"cvss_score":8.7,"headline":"Fleet server may terminate unexpectedly when handling certain gRPC requests","id":"CVE-2026-26062","kev_date_added":null,"published":"2026-05-14"},{"cvss_score":8.7,"headline":"Fleet's unbounded request body read allows remote Denial of Service","id":"CVE-2026-26061","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":8.2,"headline":"Fleet has a Windows MDM management endpoint authentication bypass","id":"CVE-2026-23998","kev_date_added":null,"published":"2026-05-14"},{"cvss_score":8.2,"headline":"Fleet Windows MDM Azure AD JWT Authentication Bypass","id":"CVE-2026-24899","kev_date_added":null,"published":"2026-05-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["fleetdm"]},"summary":"A team administrator can delete certificate templates belonging to other teams due to a missing ownership check, disrupting device enrollment and authentication workflows.","url":"https://insights.sbomify.com/CVE-2026-25963/"}
