Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-43913 in the wild and no public exploit code.\n\nAffected product: dani-garcia vaultwarden. 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-2026-43913/ (Markdown: https://insights.sbomify.com/CVE-2026-43913/index.md)","id":"CVE-2026-43913","markdown":"https://insights.sbomify.com/CVE-2026-43913/index.md","name":"CVE-2026-43913","record":{"aliases":["GHSA-937x-3j8m-7w7p"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Password manager server","requires_auth":"low_privilege","summary":"An unconfirmed organization owner can purge all vault data due to missing status checks, causing immediate data loss.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vaultwarden","vendor":"dani-garcia"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Vaultwarden is a Bitwarden-compatible server written in Rust. Prior to 1.35.5, Vaultwarden allows an unconfirmed organization owner to purge the entire organization vault. The organization invite flow uses a two-step process: accepting an invite transitions membership from Invited to Accepted, and a separate confirmation by an existing owner upgrades it to Confirmed. The POST /api/ciphers/purge endpoint uses plain Headers and only checks that the membership type is Owner without verifying that the membership status is Confirmed. An authenticated user who has been invited as an organization owner and has accepted the invite and has not yet been confirmed can call this endpoint to hard-delete all ciphers and attachments in the organization,\ncausing immediate organization-wide data loss. This vulnerability is fixed in 1.35.5.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Vaultwarden: Unconfirmed Owner Can Purge Entire Organization Vault","id":"CVE-2026-43913","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":"Vaultwarden: Brute-force protection bypass vulnerability","id":"CVE-2026-43914"},"packages":[],"prev":{"headline":"Vaultwarden: Cross-Org Group Binding Enables Unauthorized Read And Write Access Into Another Organization","id":"CVE-2026-43912"},"products":["vaultwarden"],"published":"2026-05-11","related":[{"cvss_score":9.8,"headline":"Vaultwarden vulnerable to user impersonation","id":"CVE-2024-55225","kev_date_added":null,"published":"2025-01-09"},{"cvss_score":9.6,"headline":"Vaultwarden HTML injection vulnerability","id":"CVE-2024-55224","kev_date_added":null,"published":"2025-01-09"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2024-39924","kev_date_added":null,"published":"2024-09-13"},{"cvss_score":8.7,"headline":"Vaultwarden: Cross-Org Group Binding Enables Unauthorized Read And Write Access Into Another Organization","id":"CVE-2026-43912","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":8.3,"headline":"Vaultwarden: Privilege Escalation via Bulk Permission Update to Unauthorized Collections by Manager","id":"CVE-2026-27802","kev_date_added":null,"published":"2026-03-04"},{"cvss_score":8.3,"headline":"Vaultwarden: Collection Management Operations Allowed Without `manage` Verification for Manager Role","id":"CVE-2026-27803","kev_date_added":null,"published":"2026-03-04"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["dani-garcia"]},"summary":"An unconfirmed organization owner can purge all vault data due to missing status checks, causing immediate data loss.","url":"https://insights.sbomify.com/CVE-2026-43913/"}
