——2A logic vulnerability (fail-open condition) has been identified within the Metasploit Framework's JSON-RPC web service interface. When an exception occurs during the database health check (db.check) and the environment variable MSF_WS_JSON_RPC_API_TOKEN is not explicitly set, the application resets the internal state flag msf.auth_initialized to false. The ApiToken Warden authentication strategy misinterprets this false value as an indicator that authentication is not initialized or required, thereby granting unauthenticated local access to the JSON-RPC request dispatcher.13dCVE-2026-786199.8 CRÍ47.5%
——14Punk::Plugin::TOTP versions before 0.05 for Perl accept another account's recovery code at the two-factor challenge because totp_use_recovery compares user identifiers numerically.
The helper searches the recovery model for the submitted code's digest alone, across every user's rows, so the ownership test that follows is the only thing binding a code to the account it was issued to. That test compares the row's user_id with the challenged user's id through Perl's integer coercion, and an identifier with no leading digits coerces to zero, so any two of them compare equal. User models keyed on a username, an email address or a UUID hit that case, and a numeric key compares as intended.
The challenge route feeds a submitted value to the helper once TOTP verification fails, so an attacker who knows a victim's password and holds a recovery code of their own passes the victim's second factor.15dCVE-2026-535617.4 ALT19.1%
——6An improper authentication vulnerability in HiveServer2 SAML bearer-token validation in Apache Hive 4.0.0 through 4.2.0 (and later unreleased branches) on deployments using HTTP transport with hive.server2.authentication=SAML allows an unauthenticated network attacker to authenticate as an arbitrary Hive user and obtain an authenticated HiveServer2 session via a forged Authorization: Bearer token sent to the /cliservice HTTP endpoint. Users are recommended to upgrade to 4.2.1 version that includes the fix for this issue.
Access / authorization required: No Hive credentials, SAML IdP login, or knowledge of the server signing secret is required. The attacker only needs network reachability to the HiveServer2 HTTP port (typically /cliservice), directly or through a reverse proxy such as Apache Knox that forwards unauthenticated requests to HS2. The instance must have SAML authentication enabled in HTTP mode. Deployments where Knox handles SSO and HiveServer2 uses LDAP/Kerberos (not native SAML mode) are not affected by this specific issue.14dCVE-2025-14600—30.7%
——9An insecure deserialization vulnerability in vsDesk allows a remote attacker to gain unauthorized administrative access. By manipulating application configuration data, an attacker can force the system to authenticate against an arbitrary LDAP server and provision a new administrative account.
