An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19454 in the wild and no public exploit code.\n\nAffected product: Unknown JetBackup. 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-2026-19454/ (Markdown: https://insights.sbomify.com/CVE-2026-19454/index.md)","id":"CVE-2026-19454","markdown":"https://insights.sbomify.com/CVE-2026-19454/index.md","name":"CVE-2026-19454","record":{"aliases":["GHSA-6883-v78q-c9cg"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"A network administrator can download full backups of all sites in a multisite network without Super Admin privileges due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":4.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"The JetBackup  WordPress plugin before 3.1.23.5 does not perform its multisite authorisation check before serving backup archives and job logs, allowing an administrator of the network's main site who is not a Super Admin to download a full backup of the entire network, including every site's data and the shared webroot.","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":"JetBackup 3.1.18.8 - 3.1.23.3 - Admin+ Multisite Network Backup Download","id":"CVE-2026-19454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Rockwell Automation ArmorStart® LT Stored Cross-site scripting","id":"CVE-2026-19471"},"packages":[],"prev":{"headline":"JetBackup 3.1.7.9 - 3.1.23.3 - Subscriber+ Privilege Escalation via Restore Admin User Selection","id":"CVE-2026-19453"},"products":["JetBackup"],"published":"2026-08-27","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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["Unknown"]},"summary":"A network administrator can download full backups of all sites in a multisite network without Super Admin privileges due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2026-19454/"}
