Description
The Backup Migration plugin for WordPress is vulnerable to OS Command Injection in all versions up to, and including, 2.1.5.1 due to insufficient sanitization of the file POST parameter on the restoreBackup() AJAX handler. 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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-7693 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-7693 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-7693. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
