Deeper analysis
The Tainacan plugin for WordPress is affected by CVE-2024-7135, an authorization bypass vulnerability caused by a missing capability check on the get_file function combined with directory traversal flaws. The issue impacts all versions through 0.21.7 and resides in the REST API endpoint handling background processes, allowing unauthorized file access without proper permission validation.
Authenticated attackers holding Subscriber-level privileges or higher can exploit the flaw over the network to retrieve the contents of arbitrary files on the underlying server. Successful exploitation can expose sensitive configuration data, credentials, or other restricted information stored on the host, corresponding to a CVSS 3.1 score of 6.5.
Public references, including the Wordfence advisory and the plugin's Trac changeset 3127693, indicate that the vulnerability was addressed by adding the required capability checks in a subsequent release; site administrators should update Tainacan to the patched version. The EPSS score has remained at 0.4796 with no material increase observed since disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
