Plane is an open-source project management tool. Prior to 1.4.0, Plane trusts email addresses returned by Gitea OAuth and by self-managed GitLab OAuth deployments where email confirmation is disabled, without verifying that the provider authenticated ownership of the address. An attacker can set an OAuth identity's unverified provider email to a victim's address, which Plane matches directly to the victim's existing local account. The attacker can then log in to the victim's Plane account without knowing the victim's password. GitHub, GitLab.com, and Google are not affected because those providers return verified email addresses. This issue is fixed in 1.4.0.Show less

Plane is an open-source project management tool. Prior to 1.4.0, Plane's signup flow creates a logged-in User row for any submitted email without an out-of-band ownership check, while User.email is unique=True. The authenticated user can call GET /api/users/me/workspaces/invitations/, which returns each WorkspaceMemberInvite whose email matches request.user.email. WorkSpaceMemberInviteSerializer uses fields = "all", exposing the token that protects the invitation join endpoint. An unauthenticated attacker who knows a target's email can register an account using that address, enumerate pending invitations, and accept an invitation as the target, joining a workspace at the invited role. The term pre-auth describes the attacker's initial state: the attacker has no credential before signup, while the enumeration and join requests use the session created by that signup. This issue is fixed in 1.4.0.Show less

In Bouncy Castle for Java before 1.86, the Messaging Layer Security (MLS, RFC 9420) implementation did not bind an X.509 credential to a LeafNode's signature_key. LeafNode.verify() checked a leaf's signature against the signature_key carried in the leaf itself, while the credential's X.509 certificate chain was stored but never parsed or validated, so the end-entity certificate's public key was never required to match signature_key as RFC 9420 sec. 5.3 requires. A party could therefore present another party's certificate as its credential while signing the leaf, and the enclosing KeyPackage, with an unrelated key, and be accepted under that other party's identity through KeyPackage.verify() and the Group leaf-validation path. In a deployment that admits external commits without an independent credential-admission check, an unauthenticated attacker could be admitted under a victim's X.509 identity, evict the victim (resynchronization compares whole credentials rather than signing keys), derive the current epoch, decrypt subsequent group messages, and send messages accepted as the victim. TreeKEM.LeafNode now requires the end-entity certificate's subject public key, in the cipher suite's signature encoding, to equal signature_key for an X.509 credential and rejects the leaf otherwise, including an empty chain or a certificate whose key type does not match the cipher suite; certificate-chain and identity validation to a trust anchor remain the application's responsibility per RFC 9420 sec. 5.3.1. Deployments using only basic credentials are unaffected.Show less

The Burst Statistics – Simple WordPress Analytics (Google Analytics Alternative) plugin for WordPress is vulnerable to Improper Authentication leading to Account Persistence in all versions up to, and including, 3.7.1. This is due to the `maybe_load_shared_dashboard()` handler issuing a genuine WordPress session cookie for the `burst_statistics_viewer` account to any visitor presenting a valid share token via `wp_set_auth_cookie()`, while the plugin only blocks Application Passwords for the resulting `burst_viewer` role and does not restrict the core `/wp-json/wp/v2/users/me` password update endpoint or filter the `edit_user` capability for that account — leaving WordPress core's built-in rule that any authenticated user may update their own account fully in effect. This makes it possible for unauthenticated attackers to set an attacker-chosen password on the `burst_statistics_viewer` WordPress account, constituting a permanent takeover of that limited-privilege (`view_burst_statistics`) account that persists through share-token revocation, share-token expiration, and execution of the plugin's daily `cleanup_viewer_sessions()` routine. Exploitation requires that the attacker have obtained a valid `burst_share_token`, such as one that has been shared publicly or distributed to an untrusted party.Show less

The JSON API Auth plugin for WordPress is vulnerable to Authentication Bypass via Cached Session Cookie Disclosure in all versions up to, and including, 3.1.2. The vulnerability exists because the required PI-Media/json-api parent plugin caches controller dispatch results in transients keyed solely by URI and query string, ignoring HTTP method and POST body; this causes the `generate_auth_cookie()` endpoint — which embeds a live WordPress `logged_in` cookie produced by `wp_generate_auth_cookie()` directly in its JSON response body — to serve that cached authenticated response to any subsequent unauthenticated GET request to the same URI. This makes it possible for unauthenticated attackers to retrieve a valid Administrator `logged_in` session cookie from the cached response and use it to fully authenticate as the site Administrator, including via the same plugin's `get_currentuserinfo` endpoint and any cookie-authenticated controller action. Exploitation requires the PI-Media/json-api parent plugin to be installed and active with the Auth controller enabled, and a legitimate Administrator must have POSTed to `/api/auth/generate_auth_cookie/` within the preceding 24-hour cache TTL; the nominal HTTPS enforcement gate present in `Auth.php` is trivially bypassed by supplying `insecure=cool` as a request parameter.Show less

The Divi Membership plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 2.3.0. The `process_paypal_callback` function, hooked to the `init` action, accepts a base64-encoded `paypal_param` GET parameter with no IPN validation, no cryptographic signature check, no ownership verification, and no nonce, allowing it to trust an entirely attacker-controlled user ID value that is passed directly to `wp_set_current_user()` and `wp_set_auth_cookie()`. This makes it possible for unauthenticated attackers to log in as any existing WordPress user — including administrators — by supplying an arbitrary user ID in the `paypal_param` GET parameter, resulting in full site takeover. The vulnerability is further compounded by the fact that the PayPal gateway class is instantiated unconditionally regardless of whether PayPal is enabled or configured, ensuring the vulnerable hook is always registered on every front-end request.Show less

The DevKit Pro plugin for WordPress is vulnerable to Authentication Bypass Leading to Administrator Account Takeover in all versions up to, and including, 2.3.0 This is due to the `revert_switch` handler trusting the attacker-controlled `original_user_id` cookie as the privileged identity: `verify_nonce_and_capability()` incorrectly checks the `manage_options` capability on the user identified by the cookie rather than on the actual requester via `current_user_can()`, while the switch-back form and a valid session-bound nonce are emitted publicly via `wp_footer` to any visitor — including unauthenticated users — whenever that cookie is present. This makes it possible for unauthenticated attackers to set the `original_user_id` cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the `revert_switch` handler, causing `wp_set_auth_cookie()` to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.Show less

Tapo C120 v1 and C200 V5 do not adequately protect login challenge data or sanitize attacker-controlled input processed by the MacTool handler. An unauthenticated attacker on the same local network can replay login challenge data to obtain an administrative session, enable a privileged service that becomes accessible after a reboot, and submit crafted input to execute arbitrary commands within the device management process. Successful exploitation may allow arbitrary command execution on the camera and compromise the confidentiality, integrity, and availability of the affected device. Exploitation requires access from the same local network, replay of the login challenge data, activation of the privileged service, and a device reboot.Show less
