The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Requires an authenticated administrator who is NOT a Super Admin (PR:H) - the exact scenario called out is a subsite administrator on a WordPress multisite install, where the privilege boundary between subsite admins and Super Admins is what the flaw crosses. The attacker must reach the plugin's 'File System Watcher' file viewer feature, which is missing an authorization check restricting it to Super Admins and a scoping check limiting it to only the files the watcher legitimately tracks; the concrete target is the main configuration file (wp-config.php), whose disclosure yields authentication keys, salts and, on a standard install, database credentials. Limiting factors that reduce realistic risk: valid administrator-level credentials are needed (no unauthenticated path), the meaningful privilege escalation is primarily relevant on multisite deployments that have non-super-admin administrators, there is only confidentiality impact (no write/modify), and upgrading to version 2.191 remediates it.

Impact

All signals point to a genuinely modest priority rather than an urgent threat. The CVSS 3.1 vector (AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N, base 4.4 Medium) requires high privileges (PR:H) - an already-authenticated administrator - so this is not a remote unauthenticated flaw; it is a privilege-boundary / trust-boundary weakness most meaningful on WordPress multisite, where a subsite administrator who is not a Super Admin can read network-level secrets they should not reach. EPSS is low at 0.17% (6th percentile), and the SSVC decision framework reports Exploitation: none, Automatable: no, Technical Impact: partial, all consistent with a low-urgency issue; KEV status is not listed (no active exploitation), and no public exploit is indicated in the input. The vuln.today decision label is 'this_month', i.e. schedule the patch in the normal cycle rather than treat as an emergency. The one signal that raises the stakes is impact: successful exploitation discloses wp-config.php contents - authentication keys, salts and, on a standard install, database credentials - which can enable full compromise, so C:H is justified. Net assessment: a real but contained risk gated behind administrator authentication, worth patching this cycle but not an emergency; the chief nuance to verify with the vendor is whether, on multisite, a subsite admin reading network-wide secrets should be modeled as a scope change (S:C), which the published S:U vector does not reflect.

Exploit ScenarioDerived

A non-super-admin administrator - for example a subsite administrator on a WordPress multisite network - opens the plugin's File System Watcher file viewer, which fails to restrict access to Super Admins or to only the files it legitimately tracks, and requests the main configuration file. The viewer returns wp-config.php, exposing the site's authentication keys, salts and (on a standard install) database credentials. No public exploit was identified at time of analysis; exploitation requires an existing administrator account.

AnalysisAIv1 – Oct 30, 2026

WordPress Security Plugin before 2.191 allows a non-Super-Admin administrator, including a multisite subsite administrator, to use the File System Watcher file viewer to read tracked sensitive files such as wp-config.php, disclosing authentication keys, salts and, on a standard install, database credentials. The flaw crosses the privilege boundary between subsite administrators and Super Admins and requires authenticated administrator access (PR:H); impact is confidentiality-only. This is a modest-priority issue (Decision: this_month), with EPSS 0.17% (6th percentile), SSVC exploitation none, and no public exploit identified at time of analysis; upgrading to 2.191 remediates it.

RemediationAI

Vendor-released patch: upgrade the Security Plugin, Firewall & Malware Scanner with Auto Removal WordPress plugin to version 2.191 or later; the independent assessment confirms that upgrading to 2.191 remediates the issue, and the vendor advisory is at https://wpscan.com/vulnerability/4f3e845e-2f30-4ea2-9a42-4adf01840d94/. The provided sources do not describe a separate workaround for affected versions, so updating is the complete fix; where immediate updating is not possible, exposure is limited by the fact that the attacker must already hold administrator-level credentials, and on multisite deployments the risk is concentrated in sites that assign administrator roles below Super Admin, but those conditions reduce likelihood rather than remove the flaw.

Technical ContextAI · show details

The issue is an information-exposure flaw (CWE-200) in the WordPress plugin's File System Watcher component. That feature includes a file viewer intended for Super Admins and for only the files the watcher legitimately tracks, but the affected versions do not enforce either restriction: they neither gate the viewer on the Super Admin capability nor scope the displayed path to the watcher's tracked file list. As a result, an authenticated administrator who is not a Super Admin - notably a subsite administrator on a multisite network - can access the viewer and read wp-config.php, exposing WordPress authentication keys and salts and, on a standard install, database credentials. The assessed vector is CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N, with confidentiality-only impact; the EUVD affected range is 0 to <2.191 and no CPE strings are supplied in the input. The trigger is the missing authorization and file-scoping checks in the File System Watcher viewer, not a separate memory-corruption or injection condition.

DescriptionCVE.org

The Security Plugin, Firewall & Malware Scanner with Auto Removal WordPress plugin before 2.191 does not restrict its File System Watcher file viewer to Super Admins or to the files it legitimately tracks, allowing a non-super-admin administrator, including a subsite administrator on WordPress multisite, to read the contents of sensitive tracked files such as the main configuration file and disclose the site's authentication keys, salts and, on a standard install, database credentials.
