The miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) WordPress plugin before 7.8.0 does not bind the one-time code used by its optional email-verification (Profile Completion) feature to the account it was issued for, allowing unauthenticated attackers to obtain a valid session for any account, including administrators, by requesting a code for an email address they control and replaying it against the victim's email address. Exploitation requires the Profile Completion feature to be enabled and social login to be configured.Show less

Cosmos provides users the ability self-host a home server by acting as a secure gateway to your application, as well as a server manager. In 0.22.18, `GET /cosmos/api/constellation/public-devices` discloses Constellation device metadata to a requester that supplies any non-empty Authorization header. The handler strips the string Bearer from the header but never validates the resulting token and never uses it in the database query. This vulnerability is fixed in 0.22.19.Show less

pytonapi is a Python SDK for TONAPI that provides REST API, streaming, and webhook access to the TON blockchain. From 2.0.0 to 2.2.0, TonapiWebhookDispatcher fails to validate the Authorization header when a webhook handler is registered with the documented path argument, because setup() stores bearer tokens only under the default suffix paths and never adds the custom path to the token map, so self._tokens.get(path) returns None and the authentication guard is skipped. An unauthenticated remote attacker can POST forged payloads to the custom webhook endpoint and trigger victim-defined handlers. This issue is fixed in version 2.2.1.Show less

The SAML Single Sign On – SSO Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 5.4.4. This is due to the mo_saml_validate_signature() function performing a loose boolean check on the raw tri-state integer returned by PHP's openssl_verify(), causing an error return value of -1 to be evaluated as truthy and therefore treated as a successful signature verification. This makes it possible for unauthenticated attackers to log in as any existing WordPress user, including administrators, by submitting a crafted SAMLResponse containing an attacker-controlled NameID and a deliberately malformed signature value that triggers an OpenSSL processing error — bypassing verification entirely and resulting in wp_set_auth_cookie() being called for the targeted account.Show less
