{"id":"CVE-2026-54600","summary":"Wallos: Unauthenticated database replacement via import endpoint on fresh install","details":"Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.9.4, endpoints/db/import.php has no authentication. The only guard is a user-table row count — if zero (fresh/unconfigured install), an unauthenticated attacker can replace the entire database. This issue has been patched in version 4.9.4.","aliases":["GHSA-8wqc-r9j3-rv7m"],"modified":"2026-09-04T03:30:17.405749479Z","published":"2026-08-31T20:32:58.226Z","database_specific":{"cwe_ids":["CWE-287"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54600.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/ellite/Wallos/releases/tag/v4.9.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54600.json"},{"type":"ADVISORY","url":"https://github.com/ellite/Wallos/security/advisories/GHSA-8wqc-r9j3-rv7m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54600"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ellite/wallos","events":[{"introduced":"0"},{"fixed":"ce789255b1f42edfc9f286690d223352263468b3"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"4.9.4"}]}}],"versions":["v4.9.3","v4.9.2","v4.9.1","v4.9.0","v4.8.4","v4.8.3","v4.8.2","v4.8.1","v4.8.0","v4.7.3","v4.7.2","v4.7.1","v4.7.0","v4.6.2","v4.6.1","v4.6.0","v4.5.0","v4.4.1","v4.4.0","v4.3.0","v4.2.0","v4.1.1","v4.1.0","v4.0.0","v3.3.1","v3.3.0","v3.2.0","v3.1.1","v3.1.0","v3.0.2","v3.0.1","v3.0.0","v2.52.2","v2.52.1","v2.52.0","v2.51.1","v2.51.0","v2.50.1","v2.50.0","v2.49.1","v2.49.0","v2.48.1","v2.48.0","v2.47.1","v2.47.0","v2.46.1","v2.46.0","v2.45.2","v2.45.1","v2.45.0","v2.44.1","v2.44.0","v2.43.1","v2.43.0","v2.42.2","v2.42.1","v2.42.0","v2.41.0","v2.40.0","v2.39.1","v2.39.0","v2.38.3","v2.38.2","v2.38.1","v2.38.0","v2.37.1","v2.37.0","v2.36.2","v2.36.1","v2.36.0","v2.35.0","v2.34.0","v2.33.1","v2.33.0","v2.32.0","v2.31.1","v2.31.0","v2.30.1","v2.30.0","v2.29.2","v2.29.1","v2.29.0","v2.28.0","v2.27.3","v2.27.2","v2.27.1","v2.27.0","v2.26.0","v2.25.0","v2.24.1","v2.24.0","v2.23.2","v2.23.1","v2.23.0","v2.22.1","v2.22.0","v2.21.3","v2.21.2","v2.21.1","v2.21.0","v2.20.1","v2.20.0","v2.19.3","v2.19.2","v2.19.1","v2.19.0","v2.18.0","v2.17.0","v2.16.1","v2.16.0","v2.15.0","v2.14.2","v2.14.1","v2.14.0","v2.13.0","v2.12.0","v2.11.2","v2.11.1","v2.11.0","v2.10.0","v2.9.0","v2.8.0","v2.7.0","v2.6.1","v2.6.0","v2.5.2","v2.5.1","v2.5.0","v2.4.2","v2.4.1","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0","v1.29.1","v1.29.0","v1.28.0","v1.27.2","v1.27.1","v1.27.0","v1.26.2","v1.26.1","v1.26.0","v1.25.1","v1.25.0","v1.24.0","v1.23.0","v1.22.0","v1.21.1","v1.21.0","v1.20.2","v1.20.1","v1.20.0","v1.19.0","v1.18.3","v1.18.2","v1.18.1","v1.18.0","v1.17.3","v1.17.2","v1.17.1","v1.17.0","v1.16.3","v1.16.2","v1.16.1","v1.16.0","v1.15.3","v1.15.2","v1.15.1","v1.15.0","v1.14.1","v1.14.0","v1.13.0","v1.12.1","v1.12.0","v1.11.3","v1.11.2","v1.11.1","v1.11.0","v1.10.0","v1.9.1","v1.9.0","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.1","v1.4.0","v1.3.1","v1.3.0","v1.2.0","v1.1.0","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54600.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
