Summary
RClone Manager prior to 0.2.7 starts the local rclone rcd service on 127.0.0.1:51900 with --rc-no-auth, --rc-allow-origin *, and --rc-serve. A malicious web page opened by a user while the daemon is running can send cross-origin requests to the unauthenticated local API with the user's operating-system privileges. The requests can disclose configured storage credentials and potentially access, upload, modify, or exfiltrate locally stored files. The possible command-execution impact remains unconfirmed. This issue is fixed in version 0.2.7.
Risk Assessment
An attacker can access remote storage credentials and local user files, risking data leakage and unauthorized modifications.
Recommendation
Upgrade RClone Manager to version 0.2.7 or later and avoid opening untrusted web pages while the application is running.

- CVE-2026-97693Critical
Yuxi from 0.6.0.beta1 until 0.7.1 has insufficient isolation between execution-capable Docker sandboxes and trusted application services. A low-privileged authenticated user can reach other tenants' sandbox APIs, access their files and secrets, execute commands in active sandboxes, and enumerate, create, or delete sandboxes through the unauthenticated provisioner without knowing administrator, database, or MinIO credentials.
- CVE-2026-57566Critical
Readest prior to 0.11.10 contains an unauthenticated /api/opds/proxy route that fetches an attacker-controlled URL server-side without restricting the scheme, blocking private, loopback, link-local, or metadata hosts, or revalidating destinations during redirects. The route also accepts caller-controlled outbound headers and Authorization values and reflects the upstream status and response body.
- CVE-2026-54378Critical
VitaFit cloud API before 2026-10-30 contained a broken access control vulnerability that allows any authenticated user to obtain temporary AWS credentials by calling the POST /front/user/s3/token/ endpoint. Attackers can use these improperly scoped credentials to list the shared storage bucket and read or overwrite other users' stored files.
- CVE-2026-102895Critical
GPUStack prior to 2.2.0 treated a loopback request source as the built-in administrator when force_auth_localhost was false, which was the default. A remote request could appear to originate from 127.0.0.1, allowing unauthenticated administrative access, including user and model changes, persistent administrator API-key creation, disclosure of worker and cloud-provider secrets, and code execution.
- CVE-2026-102894Critical
GPUStack from 0.7.1 until 2.2.2 contains an /auth/saml/callback endpoint that decodes SAML XML and uses its NameID and attributes to resolve or provision a user without verifying the signature, issuer, audience, destination, or time conditions. Any network client could submit an identity for an existing user, including an administrator, or provision a new account, even when SAML was not configured.
- CVE-2026-82418Critical
IBM Watson Speech Services Cartridge versions 4.0.0 through 5.4.0 contain a use-after-free vulnerability that could allow a remote attacker to execute arbitrary code.
- CVE-2026-122013Critical
A vulnerability was detected in Comfast CF-WR632AX 2.6.0.1 in an unknown functionality of /usr/bin/webmgnt within the Multipart Parser component. Manipulating the filename argument results in path traversal, the attack can be initiated remotely, the exploit is public, and the vendor did not respond.
- CVE-2025-71457Critical
vtenext 25.02 before 25.02.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to change any account password via hub/rpwd.php without token verification. Attackers knowing a valid user_name can send action=change_password to RecoverPwd::displayChangePwd() and log in as administrators lacking two-factor authentication.
- CVE-2026-121933Critical
A flaw has been found in Linksys E5350 1.0.00.037. This impacts the function save_settings of the file /wizard/apply.cgi of the Setup Wizard component. Manipulating the wizard_router_pwd argument can lead to missing authentication. The attack may be launched remotely, and the exploit has been published and may be used.
- CVE-2026-113373Critical
Sonatype Nexus Repository 3 Pro does not check the local account status when a user signs in through a configured SAML or OAuth2/OpenID Connect identity provider. A user whose account was disabled or locked by an administrator in Nexus Repository can sign in again with valid identity provider credentials for the same account and then receives a new session with the roles of that account.
Original NVD description (English source)
RClone Manager is a cross-platform GUI application designed to help users manage Rclone remotes efficiently. Prior to 0.2.7, RClone Manager starts the local rclone rcd service on 127.0.0.1:51900 with --rc-no-auth, --rc-allow-origin *, and --rc-serve. A malicious web page opened by a user while the daemon is running can therefore send cross-origin requests to the unauthenticated local API with the user's operating-system privileges. The requests can disclose configured storage credentials and potentially access, upload, modify, or exfiltrate locally stored files accessible to the user and files available through configured remotes; the advisory's possible command-execution impact remains unconfirmed. This issue is fixed in version 0.2.7.
