The handler applies `esc_attr()` — an HTML-context sanitizer that does not strip shell metacharacters — and concatenates the result, unquoted, into a `php-cli -f … bmi_restore <file> <remote>` command passed to `exec()`. This makes it possible for authenticated attackers, with Administrator-level access (or any user granted the plugin's `do_backups` capability) and above, to execute arbitrary OS commands as the web-server user, bypassing WordPress hardening constants such as `DISALLOW_FILE_EDIT` and `DISALLOW_FILE_MODS` that would otherwise prevent code execution from the admin UI. This is an incomplete fix of CVE-2023-7002, which patched the same pattern only in the `$_POST['url']` path of `handleQuickMigration()`; the equivalent mitigations (`rawurlencode()` + explicit shell-metachar replacement + double-quoting in `exec()`) were never applied to `$backupName`."}],"title":"Backup Migration <= 2.1.5.1 - Authenticated (Administrator+) OS Command Injection via 'file' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/af6a7052-6dab-42f0-a2af-0cf459d309d7?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/backup-backup/trunk/includes/ajax.php#L3025"},{"url":"https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3025"},{"url":"https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3019"},{"url":"https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3422"},{"url":"https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3444"},{"url":"https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/initializer.php#L136"},{"url":"https://plugins.trac.wordpress.org/changeset?new=3540041%40backup-backup%2Ftags%2F2.1.5.2&old=3512153%40backup-backup%2Ftags%2F2.1.5.1"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-77 Improper Neutralization of Special Elements used in a Command ('Command Injection')","cweId":"CWE-77","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":7.2,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"at1as"}],"timeline":[{"time":"2026-08-04T18:04:28.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-05T15:59:23.180874Z","id":"CVE-2026-7693","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-05T15:59:28.888Z"}}]}}
