Tutor LMS Pro <= 3.9.5 - Authentication Bypass via Social Login

The Tutor LMS Pro plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 3.9.5 via the Social Login addon. This is due to the plugin failing to verify that the email provided in the authentication request matches the email from the validated OAuth token. This makes it possible for unauthenticated attackers to log in as any existing user, including administrators, by supplying a valid OAuth token from their own account along with the victim's email address.

CVE-2025-68402 High · 8.2 CWE-287 Mar 9, 2026

FreshRSS has an authentication bypass due to truncated bcrypt hash [edge branch]

FreshRSS is a free, self-hostable RSS aggregator. From 57e1a37 - 00f2f04, the lengths of the nonce was changed from 40 chars to 64. password_verify() is currently being called with a constructed string (SHA-256 nonce + part of a bcrypt hash) instead of the raw user password. Due to bcrypt’s 72-byte input truncation, this causes password verification to succeed even when the user enters an incorrect password. This vulnerability is fixed in 1.27.2-dev (476e57b). The issue was only present in the edge branch and never in a stable release.

Rocket.Chat: 2FA bypass and login of deactivated users via EE ddp-streamer

Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0, authentication vulnerabilities exist in Rocket.Chat's enterprise DDP Streamer service. The Account.login method exposed through the DDP Streamer does not enforce Two-Factor Authentication (2FA) or validate user account status (deactivated users can still login), despite these checks being mandatory in the standard Meteor login flow. This issue has been patched in versions 7.10.8, 7.11.5, 7.12.5, 7.13.4, 8.0.2, 8.1.1, and 8.2.0.

CVE-2026-28514 Critical · 9.8 CWE-287 Mar 6, 2026

Rocket.Chat: Users can login with any password via the EE ddp-streamer-service

Rocket.Chat is an open-source, secure, fully customizable communications platform. Prior to versions 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, and 8.0.0, a critical authentication bypass vulnerability exists in Rocket.Chat's account service used in the ddp-streamer micro service that allows an attacker to log in to the service as any user with a password set, using any arbitrary password. The vulnerability stems from a missing await keyword when calling an asynchronous password validation function, causing a Promise object (which is always truthy) to be evaluated instead of the actual boolean validation result. This may lead to account takeover of any user whose username is known or guessable. This issue has been patched in versions 7.8.6, 7.9.8, 7.10.7, 7.11.4, 7.12.4, 7.13.3, and 8.0.0.

CVE-2026-28787 Critical · 9.0 CWE-287 Mar 6, 2026

OneUptime has WebAuthn 2FA bypass: server accepts client-supplied challenge instead of server-stored value, allowing credential replay

OneUptime is a solution for monitoring and managing online services. In version 10.0.11 and prior, the WebAuthn authentication implementation does not store the challenge on the server side. Instead, the challenge is returned to the client and accepted back from the client request body during verification. This violates the WebAuthn specification (W3C Web Authentication Level 2, §13.4.3) and allows an attacker who has obtained a valid WebAuthn assertion (e.g., via XSS, MitM, or log exposure) to replay it indefinitely, completely bypassing the second-factor authentication. No known patches are available.

CVE-2026-28428 Medium · 5.3 CWE-287 Mar 6, 2026

Talishar: Authentication Bypass via Empty authKey Parameter Allows Unauthenticated Game Actions

Talishar is a fan-made Flesh and Blood project. Prior to commit a9c218e, an authentication bypass vulnerability in Talishar's game endpoint validation logic allows any unauthenticated attacker to perform authenticated game actions — including sending chat messages and submitting game inputs — by supplying an empty authKey parameter (authKey=). The server-side validation uses a loose comparison that accepts an empty string as a valid credential, while correctly rejecting non-empty but incorrect keys. This asymmetry means the authentication mechanism can be completely bypassed without knowing any valid token. This issue has been patched in commit a9c218e.

CVE-2026-28471 Medium · 5.3 CWE-287 Mar 5, 2026

OpenClaw 2026.1.14-1 < 2026.2.2 - Allowlist Bypass via displayName and Cross-Homeserver localpart Matching in Matrix Plugin

OpenClaw version 2026.1.14-1 prior to 2026.2.2, with the Matrix plugin installed and enabled, contain a vulnerability in which DM allowlist matching could be bypassed by exact-matching against sender display names and localparts without homeserver validation. Remote Matrix users can impersonate allowed identities by using attacker-controlled display names or matching localparts from different homeservers to reach the routing and agent pipeline.

CVE-2026-24898 Critical · 9.8 Public exploit CWE-287 Mar 3, 2026

OpenEMR has an Unauthenticated MedEx Token Disclosure

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0, an unauthenticated token disclosure vulnerability in the MedEx callback endpoint allows any unauthenticated visitor to obtain the practice's MedEx API tokens, leading to complete third-party service compromise, PHI exfiltration, unauthorized actions on the MedEx platform, and HIPAA violations. The vulnerability exists because the endpoint bypasses authentication ($ignoreAuth = true) and performs a MedEx login whenever $_POST['callback_key'] is provided, returning the full JSON response including sensitive API tokens. This vulnerability is fixed in 8.0.0.

CVE-2026-23600 Critical · 9.8 CWE-287 Mar 2, 2026

WeGIA lacks authentication verification in adicionar_tipo_docs_atendido.php

WeGIA is a web manager for charitable institutions. Prior to version 3.6.5, the script in adicionar_tipo_docs_atendido.php does not go through the project's central controller and does not have its own authentication and permission checks. A malicious user could make a request through tools like Postman or the file's URL on the web to access features exclusive to employees. The vulnerability allows external parties to inject unauthorized data in massive quantities into the application server's storage. Version 3.6.5 fixes the issue.

Statmatic is a Laravel and Git powered content management system (CMS). Starting in version 6.0.0 and prior to version 6.4.0, Authenticated Control Panel users may under certain conditions obtain elevated privileges without completing the intended verification step. This can allow access to sensitive operations and, depending on the user’s existing permissions, may lead to privilege escalation. This has been fixed in 6.4.0.

CVE-2026-1305 Medium · 5.3 CWE-287 Feb 27, 2026

Japanized for WooCommerce <= 2.8.4 - Missing Authorization to Unauthenticated Paidy Order Manipulation

The Japanized for WooCommerce plugin for WordPress is vulnerable to Improper Authentication in versions up to, and including, 2.8.4. This is due to a flawed permission check in the `paidy_webhook_permission_check` function that unconditionally returns `true` when the webhook signature header is omitted. This makes it possible for unauthenticated attackers to bypass payment verification and fraudulently mark orders as "Processing" or "Completed" without actual payment via a crafted POST request to the Paidy webhook endpoint.

CVE-2026-26077 Medium · 6.5 Public exploit CWE-287 Feb 26, 2026

Discourse doesn't ensure webhooks require a token

Discourse is an open source discussion platform. Prior to versions 2025.12.2, 2026.1.1, and 2026.2.0, several webhook endpoints (SendGrid, Mailjet, Mandrill, Postmark, SparkPost) in the `WebhooksController` accepted requests without a valid authentication token when no token was configured. This allowed unauthenticated attackers to forge webhook payloads and artificially inflate user bounce scores, potentially causing legitimate user emails to be disabled. The Mailpace endpoint had no token validation at all. Starting in versions 2025.12.2, 2026.1.1, and 2026.2.0, all webhook endpoints reject requests with a 406 response when no authentication token is configured. As a workaround, ensure that webhook authentication tokens are configured for all email provider integrations in site settings (e.g., `sendgrid_verification_key`, `mailjet_webhook_token`, `postmark_webhook_token`, `sparkpost_webhook_token`). There's no current workaround for mailpace before getting this fix.

Cisco Catayst SD-WAN Authentication Bypass Vulnerability

A vulnerability in the API user authentication of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to gain access to an affected system as a user who has the netadmin role. The vulnerability is due to improper authentication for requests that are sent to the API. An attacker could exploit this vulnerability by sending a crafted request to the API of an affected system. A successful exploit could allow the attacker to execute commands with the privileges of the netadmin role. Note: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability. 

CVE-2026-20127 Critical · 10.0 KEV Urgent · 81 Public exploit CWE-287 Feb 25, 2026

Cisco Catalyst SD-WAN Controller and Manager Authentication Bypass Vulnerability

A vulnerability in the peering authentication in Cisco Catalyst SD-WAN Controller, formerly SD-WAN vSmart, Cisco Catalyst SD-WAN Manager, formerly SD-WAN vManage, and Cisco Catalyst SD-WAN Validator, formerly SD-WAN vBond, could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative privileges on an affected system. This vulnerability exists because the peering authentication mechanism in an affected system is not working properly. An attacker could exploit this vulnerability by sending crafted requests to an affected system. A successful exploit could allow the attacker to log in to an affected Cisco Catalyst SD-WAN Controller as an internal, high-privileged, non-root user account. Using this account, the attacker could access NETCONF, which would then allow the attacker to manipulate network configuration for the SD-WAN fabric.

Sentry: Improper Authentication on SAML SSO process allows user identity linking

Sentry is a developer-first error tracking and performance monitoring tool. Versions 21.12.0 through 26.1.0 have a critical vulnerability in its SAML SSO implementation which allows an attacker to take over any user account by using a malicious SAML Identity Provider and another organization on the same Sentry instance. Self-hosted users are only at risk if the following criteria is met: ore than one organizations are configured (SENTRY_SINGLE_ORGANIZATION = True), or malicious user has existing access and permissions to modify SSO settings for another organization in a multo-organization instance. This issue has been fixed in version 26.2.0. To workaround this issue, implement user account-based two-factor authentication to prevent an attacker from being able to complete authentication with a victim's user account. Organization administrators cannot do this on a user's behalf, this requires individual users to ensure 2FA has been enabled for their account.
