Vulnerability Overview
The BestWebSoft Google Captcha (aka reCAPTCHA) plugin before 1.13 for WordPress allows remote attackers to bypass the CAPTCHA protection mechanism and obtain administrative access via unspecified vectors.
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-804: Guessable CAPTCHA
The product uses a CAPTCHA challenge, but the challenge can be guessed or automatically recognized by a non-human actor.
Remediation
Update to version 1.13, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: reCaptcha by BestWebSoft 1.13 closes this, and updating the plugin is the step that ends it.
