Frontegg SAML SSO <= 1.0.1 - Unauthenticated Account Takeover via Unverified SAMLResponse

The Frontegg SAML SSO WordPress plugin through 1.0.1 does not verify the signature or issuer of SAML authentication responses before establishing a session, allowing unauthenticated attackers to log in as any user, including administrators, as well as to create arbitrary accounts.

Amelia Pro 9.0 - 9.8 - Unauthenticated Payment Bypass

The Booking for Appointments and Events Calendar WordPress plugin before 9.8.1 does not verify that a payment was actually taken before recording a booking as paid, trusting the payment gateway named in a public, unauthenticated booking request even when the site has never configured that gateway. This lets an unauthenticated attacker obtain confirmed, fully paid appointments and events without any payment being collected.

Temporary Login Without Password < 1.9.9 - Authenticated Temporary Access Revocation Bypass via Application Passwords

The Temporary Login Without Password WordPress plugin before 1.9.9 does not prevent a temporary user from creating an Application Password, and does not revoke one when the temporary access expires or is disabled, allowing the recipient of a temporary login to retain working access to the site over REST and XML-RPC after the administrator believes it has been withdrawn. The retained access carries whatever role was granted, which for the Temporary Login Without Password WordPress plugin before 1.9.9's main use case is Administrator.

Rox Appointment Booking < 1.2.0 - Unauthenticated Holiday Schedule Modification via REST API

The Rox Appointment Booking WordPress plugin before 1.2.0 does not perform any capability or authorization check when saving its holiday schedule, allowing unauthenticated attackers to overwrite the dates the booking system treats as unavailable, which can block legitimate bookings or open dates the site owner intended to keep closed.

Rox Appointment Booking < 1.2.0 - Unauthenticated Price Manipulation and Payment Method Restriction Bypass

The Rox Appointment Booking WordPress plugin before 1.2.0 does not verify the order total or the selected payment method against its own server-side pricing when creating a booking, allowing unauthenticated attackers to create confirmed bookings at an arbitrary price and to bypass the site's configured payment-method restrictions.

Vulnerability in the Oracle HRMS (India) product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle HRMS (India). While the vulnerability is in Oracle HRMS (India), attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle HRMS (India) accessible data as well as unauthorized update, insert or delete access to some of Oracle HRMS (India) accessible data. CVSS 3.1 Base Score 8.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N).

Tutor LMS 2.7.1 - < 4.0.8 - Read-Only API Key Privilege Escalation via REST Request Misclassification

The Tutor LMS WordPress plugin before 4.0.8 does not correctly determine whether an incoming request is addressed to its own REST API, and does not enforce the permission recorded against an API credential, allowing the holder of a read-only key to act as the administrator account that issued it.

Rox Appointment Booking < 1.2.8 - Unauthenticated Internal Notes Disclosure via Service and Category REST Routes

The Rox Appointment Booking WordPress plugin before 1.2.8 does not perform any authorization check on the endpoints that return booking service and category records, allowing unauthenticated attackers to read the private internal notes stored on each service and category.

WPBot 8.7.2 - 8.7.5 - Subscriber+ Claude AI Settings Update

The WPBot WordPress plugin before 8.7.6 does not perform a capability check on the AJAX action that saves its Claude AI provider settings, allowing users with subscriber-level access to overwrite those settings, including the API key used for the WPBot WordPress plugin before 8.7.6's outgoing AI requests.

OpenObserve: Empty external password allows authentication bypass

OpenObserve is a cloud-native observability platform. Prior to 1.1.0, the shared authentication validator in src/api/common/src/auth/validator.rs accepts an empty or whitespace-only HTTP Basic password for an account whose password_ext value is missing or empty. SSO-provisioned and migration-created users can have this state, allowing an unauthenticated attacker who knows an affected user's email address and organization to authenticate on protected non-ingestion API routes with the victim's role and permissions. A compromised privileged account can expose or modify telemetry, alerts, streams, users, and security configuration. An account with search permission can submit a DataFusion COPY ... TO statement through the search API to create or overwrite attacker-controlled files at service-process-writable locations, creating a conditional escalation to pre-authentication remote code execution. This issue is fixed in version 1.1.0.

The SAML plugin in Kong Gateway Enterprise does not enforce AudienceRestriction, allowing a valid assertion issued for another Service Provider to be replayed to authenticate to Kong.

ISE Authorization Bypass vulnerability

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to modify parts of the configuration on an affected device. This vulnerability is due to the lack of server-side validation of&nbsp;Administrator&nbsp;permissions. An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to modify descriptions of files on a specific page. To exploit this vulnerability, an attacker would need valid&nbsp;Administrator credentials.

pam_usb: deny_remote bypassed by zone-indexed IPv6 addresses (fe80::1%eth0) in pusb_tmux_has_remote_clients

pam_usb provides hardware authentication for Linux using removable media. From version 0.8.0 to before version 0.9.3, the deny_remote feature in pam_usb uses /usr/bin/w -i to detect whether the authenticating user has an active remote tmux session. In pusb_tmux_has_remote_clients() (src/tmux.c), the IPv6 detection pattern matched the address group and then immediately expected whitespace. On Linux systems with multi-homed network interfaces, w -i appends a zone index (scope identifier) to link-local IPv6 addresses — e.g. fe80::1%eth0. The %eth0 suffix appeared between the address and the next whitespace field, causing the regex match to fail even for an otherwise-matching remote session. The function returned "no remote clients" and granted access. This issue has been patched in version 0.9.3.

pam_usb: deny_remote bypassed by compressed IPv6 addresses in pusb_tmux_has_remote_clients

pam_usb provides hardware authentication for Linux using removable media. From version 0.8.0 to before version 0.9.3, the deny_remote feature in pam_usb uses /usr/bin/w -i to detect whether the authenticating user has an active remote tmux session. In pusb_tmux_has_remote_clients() (src/tmux.c), the IPv6 detection regex required exactly four explicit colon-separated groups of 1-4 hex digits (e.g. 2001:0db8:85a3:0000). Any IPv6 address in compressed notation — including loopback (::1), link-local (fe80::1), and global unicast addresses (2001:db8::1) — did not match this pattern. As a result the remote-client check silently returned "no remote clients" even when a remote tmux client was connected from such an address. This issue has been patched in version 0.9.3.

YITH WooCommerce Gift Cards <= 4.39.0 - Unauthenticated Gift Card Balance Inflation via Discounted Purchase

The YITH WooCommerce Gift Cards WordPress plugin through 4.39.0 does not reconcile the value of a gift card it issues against the amount actually paid for it, instead crediting the new card with the item's pre-discount price, which allows customers to apply an ordinary store coupon at checkout and receive a gift card worth more than they paid.

NocoDB before 2026.08.1 Client Authentication Bypass via OAuth Token Exchange

NocoDB before 2026.08.1 contains an authentication bypass vulnerability in oauth-token.service.ts that treats PKCE as a substitute for confidential client authentication, skipping client secret verification when omitted. Attackers holding a captured authorization code and PKCE verifier can mint access tokens and 60-day refresh tokens for a confidential client without knowing its secret.

Grav Login Plugin before 3.11.0 Two-Factor Authentication Bypass via /login

Grav Login plugin before 3.11.0 contains an authentication bypass vulnerability that allows attackers with an account password to skip two-factor verification when the global twofa_enabled setting is off. Attackers can sign in through the /login form, remember-me cookie, or magic link to obtain a session the API plugin accepts, gaining full account permissions including super-admin control.

OpenBao before 2.6.5 and 2.7.2 OIDC Provider Authentication Bypass via Client Credentials

OpenBao before 2.6.5 and 2.7.2 contains an authentication bypass vulnerability that allows unauthenticated callers to obtain OIDC ID tokens by abusing public clients with client_credentials enabled. Attackers who know a public client's client_id can request tokens from the identity/oidc/provider/<name>/token endpoint to impersonate the client without any secret.

n8n before 1.123.89 Authentication Bypass via Chat Trigger Embedded Chat

n8n before 1.123.89 contains an authentication bypass vulnerability in the Chat Trigger that allows unauthenticated attackers to skip n8n User Auth through the setup GET webhook route in embedded chat mode. Attackers can send unauthenticated GET requests to the chat webhook URL to read named session conversation history or trigger workflows with attacker-supplied input.
