Traefik: BasicAuth singleflight key collision allows authenticated identity spoofing
Traefik is an open source HTTP reverse proxy and load balancer. From 3.6.11 until 3.6.25 and 3.7.10, Traefik's BasicAuth middleware in pkg/middlewares/auth/basic_auth.go deduplicates concurrent password checks with a singleflight key built from the delimiter-free concatenation of password and secret, allowing an attacker who has a valid credential and the stored hash to authenticate as an unconfigured username when headerField trusts the forwarded identity. This issue is fixed in 3.6.25 and 3.7.10.

Statamic: Account takeover via OAuth email matching without email-verification check
Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, when OAuth login was enabled with a provider that does not guarantee verified email addresses, an unauthenticated attacker could sign in as an existing user, potentially including a super admin, without knowing that user's password, because the application matched OAuth identities to accounts by email address alone. Exploitation requires OAuth to be explicitly enabled with such a provider. This issue is fixed in versions 5.74.1 and 6.24.0.

OpenReception: WebAuthn passkey injection allows account takeover
OpenReception's appointment booking software provides an end-to-end encrypted appointment booking platform. Prior to version 1.0.2, the registration handler at `POST /api/auth/register/{userId}` validates the relationship between the WebAuthn challenge and the registration cookie's email but never validates that the `userId` in the URL belongs to that email. An unauthenticated attacker requests a challenge for their own email, generates a registration response with their own authenticator, and submits it against any victim user's URL. The challenge-vs-cookie email match passes, the WebAuthn ceremony validates, and `addPasskey` writes the attacker's credential into the victim's `user_passkey` rows. The next victim-email login accepts a passkey assertion from the attacker's authenticator and issues a session as the victim. User IDs are not strictly secret on this platform, but the exact set of exposure surfaces should be assessed by the maintainers. Staff-list endpoints return user IDs to authenticated tenant members per the route signature; live verification of all exposure surfaces (whether user IDs leak through any unauthenticated route, through invite-confirmation URLs, or through other administrative views) is part of the pending live PoC. Where the attacker knows the victim's email and userId, the analysis below becomes account takeover. Version 1.0.2 fixes the issue.

Estatik Real Estate Plugin < 4.3.3 - Unauthenticated Arbitrary-Recipient Mail Relay via Request Form
The Estatik Real Estate Plugin WordPress plugin before 4.3.3 does not properly enforce its anti-spam check or restrict the recipient routing of its property request form, allowing unauthenticated users to send emails to arbitrary recipients with arbitrary subject, body and Reply-To, effectively using the site as a mail relay for spam or phishing.

WPMU DEV Dashboard <= 5.0.0 - Authentication Bypass to Arbitrary Plugin Installation (Remote Code Execution) via Forged WDP_AUTH HMAC on ?wpmudev-hub= Endpoint
The WPMU DEV Dashboard plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 5.0.0. On sites not yet connected to the WPMU DEV Hub — the default state after installation — the site API key that keys the WDP-AUTH request signature is empty, making the signature verified by validate_hash() trivially forgeable; version 5.0.0 additionally removed the replay check in validate_nonce(), and the remote handler is bound to the public init hook with no capability check. This makes it possible for unauthenticated attackers to invoke privileged Hub actions — including installing and activating a plugin from an attacker-supplied URL (resulting in remote code execution), deleting plugins and themes, upgrading WordPress core, or logging in as an administrator via SSO. Sites connected to a WPMU DEV account, which have a non-empty 64-character API key, are not affected.

rust-iot-platform Authentication Bypass via Non-Validated Authorization Header
rust-iot-platform's AuthToken request-guard implementation (api/src/main.rs) only checks whether the Authorization HTTP header is present, and never validates its value against any session, token store, or signature. Any request carrying an arbitrary non-empty Authorization header (e.g. ) satisfies the guard, granting access to every endpoint protected only by this request guard.

Contest Gallery < 30.0.7 - Unauthenticated Login-Protection and 2FA Bypass via post_cg_login
The Contest Gallery WordPress plugin before 30.0.7 does not route its front-end login through the standard WordPress authentication flow, issuing an authentication cookie directly after the password check, which bypasses installed brute-force-protection and two-factor-authentication Contest Gallery WordPress plugin before 30.0.7 and enables unlimited, unthrottled password guessing against any account (including administrators) up to full account takeover.

The miniOrange 2FA WordPress plugin before 6.2.7 does not bind the second factor being configured during the pre-login two-factor challenge to the target account's existing factor, allowing an attacker who knows a user's password to rebind that user's second factor to an attacker-controlled destination, complete the challenge, and take over the account, including administrator accounts.

Login/Signup with Phone Number, OTP Verification < 1.8.71 - Unauthenticated Account Takeover via OTP Brute Force
The OTP Login With Phone Number, OTP Verification WordPress plugin before 1.8.71 does not limit the number of OTP verification attempts or invalidate a one-time login code after a wrong guess, and an unauthenticated user can request a login code for any account. Because the code is a short numeric OTP, an attacker can brute-force it and take over any account, including an administrator's.

Open WebUI: Account takeover via OAuth token exchange accepting tokens issued to any client
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.8.0 until 0.11.0, when ENABLE_OAUTH_TOKEN_EXCHANGE=True, /oauth/{provider}/token/exchange accepts a raw provider access token and validates it by calling the provider userinfo endpoint without confirming which OAuth client the token was issued to. Anyone holding an access token minted for any client registered with the same provider could exchange it for an Open WebUI session as that token user, including applications the operator does not control and has never authorized. This issue is fixed in 0.11.0.

389-ds-base: 389-ds-base: sasl plain bind installs connection credentials before account-lock check, allowing continued access as a locked account
A flaw was found in 389 Directory Server. During SASL PLAIN authentication, the server installs connection-level bind credentials before performing the account-lock check. If the account is subsequently found to be locked, the bind is reported as failed to the client, but the already-installed authenticated state on the connection is not reverted. A client that supplies valid credentials for an account that has been administratively locked can continue to use the same connection with that account's privileges, defeating account lock as an access-revocation control.
