AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Remote, low-complexity, Subscriber-authenticated (PR:L) arbitrary deletion gives I:H/A:H; direct primitive discloses nothing so C:N, unlike the vendor's chain-based C:H.

2DescriptionCVE.org
The UsersWP plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 1.2.65. This is due to insufficient validation of file-field values in the UsersWP_Validation::validate_fields() function (which falls through to sanitize_text_field() for fields of type 'file', leaving directory-traversal sequences intact) combined with the UsersWP_Forms::upload_file_remove() AJAX handler building the deletion target from the uploads basedir concatenated with the attacker-controlled metadata value without any realpath canonicalization or uploads-directory boundary check before calling unlink(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the affected site's server, including wp-config.
AnalysisAI
Arbitrary file deletion in the UsersWP WordPress plugin (versions ≤ 1.2.65) lets authenticated Subscriber-level users delete any file on the server, including wp-config.php, which can escalate into full site takeover. The flaw stems from unsanitized directory-traversal sequences in file-field metadata reaching an unlink() call in the upload_file_remove() AJAX handler. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated account of Subscriber level or above (CVSS PR:L), so the site must permit that access - most impactful on installations with open user registration enabled, where obtaining a Subscriber account is trivial. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects an easily reachable, low-complexity network attack requiring only the lowest authenticated role (Subscriber), which many WordPress sites grant via open registration - making the PR:L barrier trivial in practice. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a low-privilege Subscriber account on a UsersWP-enabled site with open registration, then submits or manipulates a profile file-field so its stored metadata contains a directory-traversal path such as '../../../wp-config.php'. Invoking the upload_file_remove AJAX handler causes the plugin to unlink() that path, deleting wp-config.php and pushing WordPress into its installation wizard, from which the attacker can point the site at a database they control and achieve full compromise. … |
| Remediation | Update UsersWP to the first release built from WordPress.org changeset 3590340 / GitHub commit ddb17ad30ff3384cda85c5f372db30b03bd45ac8, which adds proper path handling for file-field deletion; this is an upstream fix available via commit/changeset, and the exact released patched version is not independently confirmed from the provided data - treat the next release after 1.2.65 as the target and verify the fixed version on the plugin changelog before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all WordPress installations for UsersWP plugin versions ≤ 1.2.65; disable Subscriber role file management capabilities or remove user assignment pending remediation. …
