{"id":"CVE-2026-55579","summary":"Pheditor: Hardcoded default password 'admin' with no forced change enables full application compromise","details":"Pheditor is a single-file editor and file manager written in PHP. From version 2.0.1 to before version 2.0.6, Pheditor ships with a hardcoded default password admin (SHA-512 hash stored at pheditor.php:11). There is no mechanism to force a password change on first login. Any deployment using the default credentials grants an attacker full access to the file editor, file upload, and terminal features, enabling arbitrary file read/write and remote code execution. This issue has been patched in version 2.0.6.","aliases":["GHSA-p4h7-p9rj-2pq2"],"modified":"2026-08-12T03:51:32.398065627Z","published":"2026-07-27T17:54:45.156Z","database_specific":{"cwe_ids":["CWE-798"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55579.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/pheditor/pheditor/releases/tag/2.0.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55579.json"},{"type":"ADVISORY","url":"https://github.com/pheditor/pheditor/security/advisories/GHSA-p4h7-p9rj-2pq2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55579"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pheditor/pheditor","events":[{"introduced":"44378852dbc5fe07893a09f2b59648fadbed1ce1"},{"fixed":"a64eb935ce699e43f1ea60e46d47f33e2f87ffd6"}],"database_specific":{"extracted_events":[{"introduced":"2.0.1"},{"fixed":"2.0.6"},{"introduced":"0"}],"source":["AFFECTED_FIELD","DESCRIPTION","REFERENCES"]}}],"versions":["2.0.5","2.0.4","2.0.3","2.0.2","2.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55579.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
