At a glance
CVE-2026-77000 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the WP Social Media Login WordPress plugin, affecting versions <= 1.0.6. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed August 2026, reported by Khaled Alenazi.
Vulnerability Overview
The WP Social Media Login plugin for WordPress is vulnerable to Authentication Bypass via the Twitter login flow in all versions up to, and including, 1.0.6. This makes it possible for unauthenticated attackers to bypass authentication and log in as other users, such as administrators.
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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-288: Authentication Bypass Using an Alternate Path or Channel
Reaching this weakness in WP Social Media Login <= 1.0.6 takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.
The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. No fixed build of this plugin is recorded for WP Social Media Login yet, so installs running <= 1.0.6 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
