Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19453 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-2026-19453/ (Markdown: https://insights.sbomify.com/CVE-2026-19453/index.md)","id":"CVE-2026-19453","markdown":"https://insights.sbomify.com/CVE-2026-19453/index.md","name":"CVE-2026-19453","record":{"aliases":["GHSA-qpph-f397-9mqv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"A subscriber can gain administrator privileges after a site restore or migration due to missing role verification in JetBackup.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"The JetBackup  WordPress plugin before 3.1.23.5 does not verify the role or capabilities of the account it preserves across a restore or migration before granting it administrator privileges, allowing a subscriber-level user to gain administrator access after the site owner restores or migrates the site.","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 3.1.7.9 - 3.1.23.3 - Subscriber+ Privilege Escalation via Restore Admin User Selection","id":"CVE-2026-19453","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"JetBackup 3.1.18.8 - 3.1.23.3 - Admin+ Multisite Network Backup Download","id":"CVE-2026-19454"},"packages":[],"prev":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-19449"},"products":["JetBackup"],"published":"2026-09-02","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":"total"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["Unknown"]},"summary":"A subscriber can gain administrator privileges after a site restore or migration due to missing role verification in JetBackup.","url":"https://insights.sbomify.com/CVE-2026-19453/"}
