At a glance
CVE-2022-1391 is a medium-severity Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in the Cab fare calculator WordPress plugin, affecting versions <= 1.0.3. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.0.4; sites on affected versions should update now. Disclosed April 2022, reported by Hassan Khan Yusufzai - Splint3r7.
Vulnerability Overview
The Cab fare calculator WordPress plugin through 1.0.3 does not validate the controller parameter before using it in require statements, which could lead to Local File Inclusion issues.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Reaching this weakness in Cab fare calculator <= 1.0.3 takes no account at all. PHP file inclusion means a path used by include or require is built from request data, so the file that gets executed is under the caller's influence.
Including an attacker-influenced file executes its contents, which is why this class is routinely chained with an upload or log-poisoning step to reach code execution. For Cab fare calculator the fix is 1.0.4: builds <= 1.0.3 are affected, anything from 1.0.4 onward is not.
Remediation
Update to version 1.0.4, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Cab fare calculator 1.0.4 closes this, and updating the plugin is the step that ends it.
