CVE-2026-108108 High · 7.1 CWE-287 Oct 9, 2026
PHPNuxBill through 2025.3.20 CHAP Authentication Bypass via Password::chap_verify()
PHPNuxBill through 2025.3.20 contains an authentication bypass vulnerability in RADIUS CHAP verification because Password::chap_verify() returns true when the supplied response does not match. Attackers who know a valid customer or PPPoE username can log in through MikroTik hotspot or PPPoE CHAP with any incorrect password to obtain network access and consume that customer's plan.
CVE-2026-107910 High · 8.1 CWE-287 Oct 9, 2026
Authentication bypass in FalkorDB Bolt endpoint via fail-open AUTH probe error handling
An improper authentication vulnerability in the is_authenticated function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to execute graph queries without credentials through the Bolt endpoint. The function decides whether a password is required by issuing an empty AUTH command to Redis and treats only a WRONGPASS error as meaning that a password is required; any other error, such as LOADING while a dataset is being loaded, MASTERDOWN during replication failover, or OOM under memory pressure, causes the client to be treated as authenticated. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.
CVE-2026-105672 High · 8.7 CWE-287 Oct 8, 2026
Unauthenticated JSON API Authorization Bypass Vulnerability in TP-Link Tapo C325WB
TP-Link Tapo C325WB V2 contains an unauthenticated authorization bypass vulnerability in the HTTPS JSON API dispatcher on TCP port 443. An attacker on the adjacent network can append an onboarding-scoped object to a JSON request to bypass session verification and invoke privileged actions without authentication.  Successful exploitation may allow an unauthenticated adjacent-network attacker to access live video and audio, modify device settings, and obtain sensitive device information or secrets.

IBM DataPower Gateway Improper Authentication
IBM DataPower Gateway 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 could allow a remote attacker to obtain administrative access due to failure to reject empty passwords during LDAP authentication.
CVE-2026-105832 Medium · 4.3 CWE-287 Oct 8, 2026
EspoCRM before 10.0.6 Two-Factor Authentication Bypass on Unauthenticated Routes
EspoCRM before 10.0.6 contains an authentication bypass vulnerability that accepts a login stopped at the second factor on routes not requiring authentication. Attackers knowing a 2FA-enabled user's username and password can skip the second factor to read config parameters not exposed publicly.
CVE-2026-103646 Critical · 9.8 CWE-287 Oct 8, 2026
Ultimate Multisite < 2.17.0 - Unauthenticated Authentication Bypass via 'email_address' Parameter
The Ultimate Multisite WordPress plugin before 2.17.0 does not require authentication before a logged-out checkout is linked to, and logged in as, an existing WordPress account matching the submitted email address, and its duplicate-account check normalizes that address differently from the lookup used to create the customer, so an unauthenticated attacker can log in as any existing user, including a Network Super Admin, whose email address they know. This bypass is not addressed by the 2.15.1 fix for CVE-2026-75957 and remains exploitable in all versions up to and including 2.16.1, the releases that fix was expected to cover. Exploitation requires a checkout form configured without a password field (auto-generated password) and a target account that has no existing customer record in the Ultimate Multisite WordPress plugin before 2.17.0.
CVE-2026-107228 Medium · 6.8 CWE-287 Oct 7, 2026
AsyncHttpClient CookieStore Silently Overrides Caller's Explicit Cookie Header via setHeader (Bypass of CVE-2024-53990 Fix)
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.1.0 until 3.0.14, the enabled-by-default cookie store replaces a Cookie header explicitly supplied through setHeader or addHeader whenever the store contributes any cookie for the origin. In a shared client, stored cookies originating from one user can replace a different user's request cookie, causing the request to execute under the wrong session. This bypasses the earlier CVE-2024-53990 remediation, which covered cookies supplied through addCookie but not a directly supplied header. This issue is fixed in version 3.0.14.
CVE-2026-46437 Medium · 4.8 CWE-287 Oct 7, 2026
wger: API credentials remain valid after logout/password change
wger is a free, open-source workout and fitness manager. Versions prior to 2.6 have a vulnerability in the authentication/session lifecycle of `wger` where bearer-style API credentials remain valid after a user logs out and after a user changes their password. An attacker who steals a victim’s DRF authtoken (`Authorization: Token ...`) or JWT refresh token can continue to access protected `/api/v2/*` endpoints until the token is manually rotated/deleted (DRF token) or naturally expires (JWT refresh). Version 2.6 contains a patch.
CVE-2026-107180 High · 7.1 CWE-287 Oct 7, 2026
MISP: Forced TOTP Enrolment Bypassed via Non-Browser Request Types on otp_required Instances
On MISP instances configured to require TOTP enrolment (Security.otp_required), the enforcement of the mandatory two-factor authentication setup applied only to standard browser requests. An authenticated user who had not yet enrolled in TOTP could bypass the forced setup by issuing any non-browser request type, including AJAX/XHR calls, REST API requests, .json format URLs, restSearch queries, or automation actions. Because these machine-readable request shapes cannot follow the redirect that the browser path uses to send the user to the TOTP enrolment page, the guard simply skipped the check and the user retained full access to the instance without completing the required second-factor setup. The initial fix (commit 8deb0619e) added a guard specifically for AJAX requests. A follow-up fix (commit 6b527ba6e) broadened the guard to cover every non-browser request shape, while preserving the exemption for identities authenticated via API key (logged_by_authkey flag). Impact: an authenticated user on an otp_required instance can operate with full access indefinitely without enrolling in TOTP, nullifying the instance-level two-factor authentication policy. Affected version: <2.5.48
CVE-2026-107162 Medium · 6.8 CWE-287 Oct 7, 2026
Express Gateway through 1.16.11 OAuth 2.0 Refresh Token Validation Bypass
Express Gateway through 1.16.11 contains an authentication bypass vulnerability in the OAuth 2.0 refresh_token grant that fails to validate the token secret or issuing client. Attackers with any valid client credentials and the identifier portion of another user's refresh token can obtain that user's access token and impersonate them against oauth2-protected APIs.
CVE-2026-83540 High · 8.8 CWE-287 Oct 7, 2026
wolfSSHd on Windows race condition leading to logon token reused across connections
When password or public key authentication is used with the Windows port of wolfSSHd, the Windows logon token acquired for one authenticated connection is not released before a token is acquired for a subsequent connection, resulting in user login poisoning between connections. A less privileged user with a valid account on the server can exploit this to force a login as a more privileged user. The vulnerability was introduced with the initial Windows port of wolfSSHd in wolfSSH version 1.4.15 and affects all versions through 1.5.0. Non-Windows builds of wolfSSHd are not affected.
CVE-2026-101023 Critical · 9.1 CWE-287 Oct 6, 2026
Gitea OAuth2 refresh token grant accepts access tokens
Gitea's OAuth2 token endpoint verified the signature and grant of a token submitted with the `refresh_token` grant type, but not that the token was a refresh token. An unexpired access token for the same OAuth2 application and grant could be exchanged for a new access token and refresh token. Whoever holds such an access token could keep access beyond the token's original lifetime.
CVE-2026-106488 High · 8.1 CWE-287 Oct 6, 2026
Backstage: Improper authentication in the OIDC provider
Backstage is an open framework for building developer portals. Prior to 0.4.20, the @backstage/plugin-auth-backend-module-oidc-provider package is affected by improper authentication in the oidc provider. Deployments using OIDC email-based identity resolution with a provider that permits unverified email addresses may allow an authenticated provider user to assume another catalog identity. This may grant access and permissions associated with that user. No direct availability impact is demonstrated. This issue is fixed in version 0.4.20.
CVE-2026-106460 Medium · 6.8 CWE-287 Oct 6, 2026
Backstage: Explicit negative email verification can be ignored during shared OAuth profile normalization
Backstage is an open framework for building developer portals. From 0.3.0 until 0.6.15 and 0.7.5, the @backstage/plugin-auth-node package did not consistently honor explicit negative email verification during shared OAuth profile normalization. The affected paths include a selected profile email marked verified: false, a matching raw provider email marked email_verified: false, and an email obtained only from an ID token marked email_verified: false. Exploitation requires an admitted identity-provider user who can supply or change an unverified email and a deployment that uses the selected profile email to resolve catalog identities. The verification metadata must apply to the selected email; an absent email_verified claim alone is not affected. In an affected configuration, the user may assume another catalog identity and obtain its associated access and permissions. This issue is fixed in versions 0.6.15 and 0.7.5.
CVE-2026-106457 Medium · 6.8 CWE-287 Oct 6, 2026
Backstage: Insufficient audience validation in the Cloudflare Access auth provider
Backstage is an open framework for building developer portals. From 0.1.0 until 0.5.0, the @backstage/plugin-auth-backend-module-cloudflare-access-provider package is affected by insufficient audience validation in the cloudflare access auth provider. The Cloudflare Access auth provider verifies a token's signature and team issuer, but affected versions do not verify that the token was issued for the Backstage application. A user holding a valid token for another Access application in the same Cloudflare Zero Trust team may therefore be able to authenticate to Backstage if that token reaches the auth endpoint without the Backstage application's audience already being enforced upstream. Cloudflare Access normally evaluates the protected application before forwarding requests. This issue is fixed in version 0.5.0.
CVE-2026-96404 High · 8.1 CWE-287 Oct 6, 2026
Gitea installer authentication bypass for existing accounts
When Gitea's web installer is reachable against a database that already contains users, such as after `INSTALL_LOCK` has been reset to `false`, submitting the install form with an administrator username matching an existing account issued an authenticated session for that account without verifying its password. If the account is an administrator, the session grants full administrative access, including changing the account's password. Databases with a single user also did not require the reinstall confirmation.
CVE-2026-79796 Critical · 9.8 CWE-287 Oct 6, 2026
Authentication Bypass Vulnerabilities in ClearPass Policy Manager
Vulnerabilities have been identified in the affected interface of ClearPass Policy Manager that could potentially allow an unauthenticated remote attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to gain unauthorized access to the affected system.
CVE-2026-76752 Critical · 9.8 CWE-287 Oct 6, 2026
Authentication Bypass Vulnerabilities in HPE Networking ClearPass Policy Manager Allow Unauthorized Administrative Access
Authentication bypass vulnerabilities exist in the web-based management and API interfaces of HPE Networking ClearPass Policy Manager. Successful exploitation could allow an unauthenticated remote attacker to circumvent existing authentication controls and gain administrative access to the affected system.
CVE-2026-76743 Critical · 9.8 CWE-287 Oct 6, 2026
Authentication Bypass Vulnerability in the Management Interface of AOS-S
A vulnerability have been identified in the management interface of AOS-S that could potentially allow an unauthenticated remote attacker to circumvent existing authentication controls if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to gain unauthorized access to the affected system.
CVE-2026-73278 Critical · 9.8 CWE-287 Oct 6, 2026
Gitea WebAuthn bypass during OAuth and OIDC sign-in
Gitea's OAuth2 and OpenID Connect sign-in paths do not require a WebAuthn challenge when WebAuthn is the account's only configured second factor. A party able to authenticate through the affected external identity flow can obtain a full session without the passkey verification enforced during password login. One affected path can also persist an external identity link, extending the compromise beyond the initial session; accounts with TOTP configured are outside the reported WebAuthn-only scenario.
CVE-2026-105305 Medium · 5.4 CWE-287 Oct 6, 2026
Keycloak-services: keycloak-services: device authorization grant bypasses per-client minimum.acr.value enforcement
A flaw was found in the OIDC implementation of Keycloak, specifically within the Device Authorization Grant flow. This component allows devices with limited input capabilities to obtain security tokens. The issue occurs because the flow fails to check the minimum authentication level required by a client configuration. This allows an attacker who has stolen a user's password to bypass mandatory multi-factor authentication and gain unauthorized access to the Keycloak Admin REST API.
CVE-2026-94271 Medium · 5.3 CWE-287 Oct 6, 2026
Deema Payment Gateway <= 1.1.2 - Unauthenticated Payment Confirmation Forgery via Unverified Success Return
The Deema Payment Gateway WordPress plugin through 1.1.2 does not verify the payment with the payment provider when handling the return from the hosted checkout, and does not check the payment status or amount, allowing unauthenticated users to have orders marked as paid without any payment being taken.
