MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires only that a target WordPress site has the WebToffee WordPress Backup & Migration plugin (slug wp-migration-duplicator) installed and active at version <= 1.6.0; per the CVSS vector (AV:N/AC:L/PR:N/UI:N) no authentication, user interaction, or special configuration is needed for the default deployment. The primary limiting factor is simply the presence of this specific plugin at a vulnerable version - this is not a core WordPress flaw, so the realistic footprint is bounded by that plugin's install base, and any site that has upgraded past 1.6.0 is not affected. |
| Impact | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, base 7.5) describes a remotely reachable, low-complexity flaw needing no authentication and no user interaction, with high confidentiality impact but no integrity or availability effect - a classic unauthenticated read/exposure primitive consistent with CWE-862 (Missing Authorization). For a backup/migration plugin this profile is meaningful: the confidentiality-only impact plausibly maps to unauthorized access to backup archives, which for WordPress commonly contain full database dumps (including wp_users hashes, secret keys, and site content). No EPSS score, no CISA KEV listing, and no public POC were provided, so there is no signal of active exploitation or automation at this time - status is 'no public exploit identified at time of analysis.' No SSVC decision data was supplied. This is a genuine priority for sites actually running WebToffee's WordPress Backup & Migration <= 1.6.0 (unauthenticated + C:H is a favorable target profile), but the absence of EPSS/KEV/POC keeps it below actively-exploited emergencies; treat as a prompt-patch item rather than a fire drill. Note the 'Authentication Bypass' tag is imprecise - the CWE and description point to broken authorization (access control), not authentication bypass. |
| Exploit ScenarioDerived | A remote, unauthenticated attacker sends a crafted HTTP request to a vulnerable endpoint of the WordPress Backup & Migration plugin (<= 1.6.0) that fails to enforce an authorization/capability check, retrieving data or backup content they should not be able to read. Because no login, user interaction, or special complexity is required (PR:N/UI:N/AC:L), the request can be issued directly against any exposed site running the plugin. No public exploit code has been identified at the time of analysis. |

Alert meAnalysisAIv1 – Sep 30, 2026
Unauthenticated access control failure in the WebToffee WordPress Backup & Migration plugin (slug wp-migration-duplicator) through version 1.6.0 allows remote attackers to read protected resources without credentials or user interaction; the CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N (base 7.5) reflects a high confidentiality impact with no integrity or availability effect. Any WordPress site with this plugin installed and active at or below 1.6.0 is exposed, while sites that have upgraded past 1.6.0 or that do not run the plugin are unaffected. No public exploit code has been identified at time of analysis, and this CVE is not listed in CISA KEV.
RemediationAI
No vendor-released patch version for CVE-2026-97197 is identified in the provided references, so the first step is to check the WebToffee plugin page and the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/wp-migration-duplicator/vulnerability/wordpress-wordpress-backup-migration-plugin-1-6-0-broken-access-control-vulnerability?_s_id=cve) for a release above 1.6.0 and upgrade as soon as one is confirmed; absence of a listed fix version in this data is not confirmation that no patch exists. If the plugin is not essential, deactivating and deleting it removes the attack surface entirely, though that forfeits backup/migration functionality. Where the plugin must remain active at a vulnerable version, restrict access to the plugin's endpoints at the web server or WAF layer - block unauthenticated requests to the plugin's admin-ajax actions, REST routes, and direct PHP files, and deny external access to backup or migration directories - accepting the trade-off that overly broad blocks can break legitimate plugin features and that WAF rules require tuning and maintenance. Additional compensating measures include placing the site behind authentication at the edge, limiting access to trusted IP ranges, monitoring web logs for anomalous requests to plugin paths, and keeping WordPress and all plugins patched.

Technical ContextAI · show details
The flaw is a missing authorization check (CWE-862) in a plugin-supplied endpoint that is reachable over HTTP in the default WordPress deployment. WordPress plugins frequently expose AJAX actions, REST routes, or direct PHP files intended for privileged users; when such a handler omits a capability check (for example current_user_can) or a nonce verification, any remote caller can invoke it. Here the CVSS vector AV:N/AC:L/PR:N/UI:N confirms the endpoint is network-reachable, low-complexity, unauthenticated, and requires no user interaction, while scope is unchanged and only confidentiality is impacted - a classic unauthenticated read/exposure primitive. Because the product is a backup and migration tool, the protected resources at risk are likely backup archives, database dumps, or site configuration data that the plugin generates and stores. The CPE cpe:2.3:a:webtoffee:wordpress_backup_&_migration:*:*:*:*:*:*:*:* identifies the WebToffee WordPress Backup & Migration plugin as the affected component, and this is not a core WordPress issue.

Executive ViewAI
Organizations running the WebToffee WordPress Backup & Migration plugin at version 1.6.0 or earlier have a remote, unauthenticated exposure that could disclose protected site or backup data. Because no public exploit has been identified at time of analysis and no vendor-released patch identified at time of analysis, leadership should treat this as a manageable but urgent exposure requiring inventory, isolation, and vendor follow-up.
Remove or deactivate the wp-migration-duplicator plugin on affected WordPress sites; restrict plugin endpoints by WAF/IP allowlisting; require authentication at the reverse proxy; monitor and alert on anomalous access to backup or migration resources; isolate affected sites; request a patch timeline from WebToffee.
