Nextcloud: Bypass of second factor authentication on DAV endpoints
Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.9, and 33.0.0 to before 33.0.3, a pre-2FA session cookie (created after successful password authentication but before TOTP completion) could be reused as a Bearer token to authenticate against DAV endpoints, granting read/write access and bypassing mandatory two-factor authentication. It is recommended that the Nextcloud Server is upgraded to 33.0.3 or 32.0.9. It is recommended that the Nextcloud Enterprise Server is upgraded to 33.0.3, 32.0.9, 31.0.14.5, 30.0.17.9 or 29.0.16.16

Nextcloud: Two-Factor Authentication Bypass via Pending Session Token Replay
Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.9, and 33.0.0 to before 33.0.3, an authentication bypass vulnerability allowed attackers with knowledge of a user's password to circumvent two-factor authentication (2FA) protections. When a user initiated login with valid credentials on a 2FA-enabled account, the system created a temporary session token before enforcing the second factor challenge. This token could be extracted and replayed via HTTP Basic Authentication to gain unauthorized access to authenticated endpoints. It is recommended that the Nextcloud Server is upgraded to 33.0.3 or 32.0.9. It is recommended that the Nextcloud Enterprise Server is upgraded to 33.0.3, 32.0.9, 31.0.14.5, 30.0.17.9 or 29.0.16.16

Nextcloud: Files Lock app allows users to lock and unlock files of other users
Nextcloud is an open source content collaboration platform. In Nextcloud Server from versions 32.0.0 to before 32.0.2, and 33.0.0 to before 33.0.1, the files_lock app did not properly validate the ownership of files when processing DAV lock and unlock requests. An authenticated user could lock or unlock files belonging to other users by targeting their absolute WebDAV paths. Additionally, lock tokens were disclosed to unauthorized callers in error responses, allowing attackers to remove token-based locks placed by other users' client applications. It is recommended that the Nextcloud Server is upgraded to 32.0.2 or 33.0.1. It is recommended that the Nextcloud Enterprise Server is upgraded to 31.0.14.4 or 32.0.2 or 33.0.1

CWE-287 May 29, 2026
Openshift/router: openshift/router: mtls client certificate spoofing via unstripped x-ssl-client headers on http frontend
A flaw was found in the OpenShift Router. When a Route has `insecureEdgeTerminationPolicy` set to Allow, the HTTP frontend does not remove `X-SSL-Client-*` headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted `X-SSL-Client-*` headers. As a result, backends relying on these headers for mutual TLS (Transport Layer Security) authentication can be bypassed, enabling the attacker to impersonate client certificate identities.

CWE-287 May 29, 2026
OTP Login With Phone Number, OTP Verification <= 1.8.60 - Unauthenticated Authentication Bypass via Firebase OTP Verification
The OTP Login With Phone Number, OTP Verification plugin for WordPress is vulnerable to authentication bypass in versions 1.8.50 through 1.8.60. This is due to the Firebase verification flow in the `lwp_ajax_register` AJAX handler not binding the Firebase session to the phone number supplied in the request. The `idehweb_lwp_activate_through_firebase()` function validates that a Firebase OTP session is legitimate, but the `phoneNumber` returned by Firebase is never compared against the victim's stored phone number. This makes it possible for unauthenticated attackers to authenticate as any user who has a phone number stored in user meta, including administrators, by verifying their own Firebase session and supplying the victim's phone number in the same request.

PyJWT: Public-key JWK accepted as HMAC secret enables forged HS256 tokens when mixed families are allowed
PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer public key as the secret key for HMAC algorithm. This vulnerability is fixed in 2.13.0.

CWE-287 May 27, 2026
pam_usb: OTP pad authentication bypass via missing system pad check and uninitialized RNG buffer
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, the pusb_pad_compare() function in src/pad.c only verified that the user-side pad (~/.pamusb/device.pad) could be read, but did not enforce that the system-side pad (the pad file on the USB device) was also present and readable. If the user-side pad was deleted or unreadable, the function returned a failure that was treated as non-fatal in certain code paths, allowing authentication to succeed without the USB device being verified. A local user can delete their own ~/.pamusb/device.pad to remove the USB device requirement and authenticate without the physical device. This vulnerability is fixed in 0.9.0.

Authentication bypass vulnerability found in Aspera High-Speed Transfer Server for Cloud Pak for Integration
IBM Aspera HSTS for CP4I 1.5.1 through 1.5.19 is affected by an authentication bypass vulnerability. A transfer client may be able to take advantage of this vulnerability to access files in the server's local storage that they should not have access to, when specific restriction settings are not in place.
CVE-2026-8994

CWE-287 May 27, 2026
Login with NEAR <= 0.3.3 - Authentication Bypass via 'account' Parameter
The Login with NEAR plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 0.3.3. The `ajaxLoginWithNear()` function — registered as a `wp_ajax_nopriv` action and therefore reachable by unauthenticated users — accepts an attacker-supplied `account` POST parameter and issues a valid WordPress authentication cookie based solely on a substring check for `.near`, with no nonce verification, cryptographic signature validation, challenge-response exchange, or any proof that the requester controls the corresponding NEAR wallet. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, whose email address matches the deterministic `<account>@near.org` pattern derived from the supplied `account` value. If no matching user exists, the handler automatically creates and authenticates a new WordPress account for the attacker-controlled identifier, providing a further avenue for unauthorized account creation.
CVE-2026-44847
High · 7.5
CWE-287 May 26, 2026
MaxKB: Webhook Trigger Authentication Bypass
MaxKB is an open-source AI assistant for enterprise. Prior to 2.9.0, MaxKB's webhook trigger endpoint (/api/trigger/v1/webhook/{trigger_id}) is accessible without authentication. The WebhookAuth class unconditionally returns (None, {}), which Django REST Framework interprets as successful authentication. Combined with optional per-trigger token verification and no backend enforcement of token requirements, any unauthenticated attacker who knows a valid trigger ID can invoke webhook triggers to execute their bound tasks. This vulnerability is fixed in 2.9.0.

Kavita Improper Authentication Allows JWT Issuance for Any User
Kavita is a cross platform reading server. Prior to 0.9.0.2, an Improper Token validation flaw permits a remote and unauthenticated threat actor to request a JWT for any user including admins given knowledge of their username. This vulnerability is fixed in 0.9.0.2.
