Summary
The InstaWP Connect – 1-click WP Staging & Migration plugin for WordPress (versions up to and including 0.1.4.1) is vulnerable to privilege escalation. The plugin registers its admin page using a role name returned by InstaWP_Setting::get_allowed_role() as the required capability, and generate_section_field() renders the master API key as a plain-text HTML input without additional manage_options checks. An authenticated attacker with Subscriber-level access or above can read the plaintext master API key, use its SHA-256-derived secret as a bearer token in the plugin's REST API, and call POST /wp-json/instawp-connect/v2/auto-login to mint a 30-second single-use login URL that sets an administrator authentication cookie.
Risk Assessment
A low-privileged attacker can fully take over the WordPress site, gaining administrative access and performing any actions. This requires the site to be actively connected to InstaWP and an administrator to have added the attacker's role to the Sync Tab Access list, though a mixed configuration retaining administrator alongside a lower role still exposes the API key.
Recommendation
Immediately update the InstaWP Connect plugin to a version newer than 0.1.4.1 if available, or disable it. Review and remove lower roles from the instawp_sync_tab_roles list and verify whether the API key has been exposed.

VitaFit cloud API before 2026-10-30 contained an authentication bypass vulnerability that allows remote attackers to obtain a full session for a victim's account by submitting a linked Google or Facebook account identifier to the POST /front/login/sns/ endpoint without providing proof of ownership from the identity provider. Attackers can forge a login using an identifier exposed through account enumeration to read and modify the victim's profile and delete the account's authentication record.

GLPI is a free asset and IT management software package. From 11.0.0 until 11.0.8, during the login phase, an unauthenticated user could use a crafted URL to skip one-time-password verification, defeating two-factor authentication. This issue is fixed in version 11.0.8.

Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to services. From 2.2.0 until 2.12.0, SendEmailVerification binds an email-verification token only to the user's identifier, while UpdateUser can change the account email without invalidating the outstanding token and VerifyEmail marks the current address as verified. An ordinary user can request a token for an address they control, change the account to an arbitrary unused address, and redeem the old token so Pocket ID publishes the new address with email_verified set to true.

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.

Original NVD description (English source)
The InstaWP Connect – 1-click WP Staging & Migration plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 0.1.4.1 This is due to the plugin registering its admin page via `add_management_page()` using a role name returned by `InstaWP_Setting::get_allowed_role()` as the required capability — which WordPress resolves as a real capability match for any user holding that role — combined with `generate_section_field()` rendering the master API key from the `instawp_api_options` option directly as the `value` attribute of a plain-text HTML input with no additional `manage_options` or equivalent capability check. This makes it possible for authenticated attackers with Subscriber-level access and above to read the plaintext master API key, use its SHA-256-derived secret as a bearer token accepted by the plugin's REST API `validate_api_request()`, and call `POST /wp-json/instawp-connect/v2/auto-login` to mint a 30-second single-use login URL that sets an administrator authentication cookie — fully escalating their privileges. Exploitation requires the site to be actively connected to InstaWP and an administrator to have added the attacker's role to the plugin's Sync Tab Access list (`instawp_sync_tab_roles`); notably, the settings tab suppression logic only hides the tab when `administrator` is absent from the list entirely, meaning a mixed configuration retaining administrator alongside a lower role still serves the full settings page — including the API key — to the lower-privileged user.
