CVE-2026-72825

Grav API Plugin before 1.0.13 API-key scope cap bypass via ReportsController

The getgrav/grav-plugin-api plugin before 1.0.13 contains an API-key scope cap bypass in the POST /reports/twig-content/allowlist endpoint (ReportsController). The endpoint enforces requirePermission('api.config.write') followed by a bare isSuperAdmin() check instead of requireSuper(). Because isSuperAdmin() reads access.api.super directly and never consults api_key_scopes, a least-privilege API key scoped to api.config.write minted on a super account passes the gate, allowing an attacker to append attacker-chosen tokens to the security.twig_sandbox allowlist (persisted to user/config/security.yaml). Widening the allowlist turns any subsequent Twig-in-content render into an SSTI/RCE sink.

CVE-2026-72826

Grav API Plugin before 1.0.13 Scope Bypass via createApiKey

The getgrav/grav-plugin-api plugin before 1.0.13 fails to validate that the scopes of a newly created API key are a subset of the caller's scopes in createApiKey. The self-target path of requireApiKeyPermission() requires only the baseline api.access scope, and the new key's scopes are read directly from the request body with no subset check. An attacker holding a minimal-scope API key on a super account can submit an empty scopes array to mint an unscoped, full-access super key, bypassing scope restrictions (and enabling further chains such as configuration write to RCE).

Grav API Plugin before 1.0.4 Password Reset Token Poisoning via admin_base_url

The Grav API plugin (grav-plugin-api) before 1.0.4 does not validate the origin of the client-supplied admin_base_url field in the POST /api/v1/auth/forgot-password endpoint. The sanitizeHttpUrl() function only checks that the URL scheme is http/https and never verifies the host against the server's own origin, so an attacker can supply an arbitrary host. As a result, an unauthenticated attacker can cause the password reset email sent to a victim to contain a reset link pointing at an attacker-controlled server; when the victim follows the link, the valid reset token is disclosed to the attacker, enabling full account takeover. The vulnerable base URL can also be influenced via the Referer or Origin headers.

Grav API Plugin before 1.0.42 Cache Exhaustion and Page Permission Bypass

Grav API plugin (grav-plugin-api) 1.0.40 before 1.0.42 caches a full translation dictionary for every well-formed language code sent to the unauthenticated GET /api/v1/translations/{lang} endpoint, and 1.0.16 before 1.0.42 fails to check target and destination page rules in the sync and batch copy endpoints. Unauthenticated attackers can send small requests that each store about 560 KB to exhaust disk or APCu, while accounts with api.pages.write can overwrite translations or create pages that page-level rules deny.

Grav API Plugin before 1.0.36 Privilege Escalation via Scalar Access Grants

Grav grav-plugin-api before 1.0.36 contains a privilege escalation vulnerability that allows delegated user managers to obtain super-admin access by storing positive scalar admin or api parent grants. Attackers with api.users.write can edit account access maps or invitations so the inheriting permission resolver satisfies requireSuper checks, accessing super-only API endpoints.

Grav API Plugin before 1.0.36 Disabled Account Session Access Bypass

The Grav API plugin (grav-plugin-api) before 1.0.36 contains an improper session validation vulnerability that allows disabled accounts to keep API access, because SessionAuthenticator does not enforce account state. Disabled users can reuse an already authorized browser or remember-me session to call API endpoints until expiry, defeating operator revocation.

Grav API Plugin before 1.0.20 Authentication Bypass via Host Header

Grav API plugin versions before 1.0.20 build password reset links from the untrusted Host header in the forgot-password endpoint, allowing unauthenticated attackers to redirect reset tokens to attacker-controlled domains. Attackers can send password reset requests for any account with a malicious Host header, intercept the reset token from victim emails, and complete account takeover including super-admin accounts.

grav-plugin-api 1.0.0 through 1.0.19 Privilege Escalation via Dot-Keyed Super Flag

grav-plugin-api versions before 1.0.20 contain a privilege escalation vulnerability in the InvitationsController where the stripSuperFlags() method only removes nested super flags but fails to strip dot-keyed equivalents like api.super. A non-super user manager with api.access and api.users.write permissions can create an invitation with a dot-keyed super flag in the access payload that bypasses the guard and persists to the new account. Attackers can accept the invitation through the public endpoint without real invitee interaction to create a super-admin account and immediately receive a valid JWT for full site control.

Grav API Plugin Authentication Bypass via Group-Inherited Super

grav-plugin-api before 1.0.20 fails to validate group-inherited super permissions in user-management guards, allowing non-super user managers to modify super-admin accounts. Attackers with api.access and api.users.write can patch password fields on group-super accounts to gain full administrative control.

Grav API Plugin: CORS 'Access-Control-Allow-Origin: *' on Authenticated API Responses

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.0-rc.16, the Grav API plugin CorsMiddleware returns Access-Control-Allow-Origin: * and permissive OPTIONS responses for authenticated /api/v1 endpoints. JavaScript from any origin can submit an attacker-obtained JWT through the Authorization or X-API-Token header, read the authenticated response, and perform write operations with the token owner's privileges, enabling data exfiltration and account modification. This issue is fixed in version 1.0.0-rc.16.

Grav API Plugin : API Key 'scopes' Never Enforced - Delegated Least-Privilege Keys Carry Full User ACL

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, the Grav API plugin ApiKeyManager::generateKey() stores a declared scopes array, but ApiKeyAuthenticator::authenticate() does not read keyData[scopes] and returns the owning user's complete identity. AbstractApiController::requirePermission() consequently evaluates the full user ACL, so a key issued for a read-only scope can perform every write, delete, and administrative operation available to the owner. This issue is fixed in version 1.0.6.

Grav API Plugin: non-super api.users.write manager -> super-admin via createApiKey (incomplete fix of CVE-2026-59190); + 2FA strip of super

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, Grav API plugin UsersController::createApiKey(), generate2fa(), and disable2fa() omit the accessGrantsSuper() target check used by sibling user mutation endpoints. A non-super account with api.users.write can mint an API key bound to an access.api.super target through requireApiKeyPermission(), obtain the target's full privileges because key scopes are not enforced, and create persistent super-administrator access; the same missing check also permits rotating or disabling the target's two-factor authentication. This issue is fixed in version 1.0.6.

Grav API Plugin: Stored XSS via SVG Upload - API Media Pipeline Bypasses Sanitizer

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.2, the Grav API plugin POST /api/v1/media pipeline in HandlesMediaUploads::processUploadedFile() validates an SVG filename extension but does not invoke Security::sanitizeSVG(). An attacker with api.media.write permission can store an SVG containing JavaScript, and the server returns the file as Content-Type: image/svg+xml so the script executes when a victim opens it, allowing session data theft and authenticated actions. This issue is fixed in version 1.0.2.

Grav API Plugin: JWT Access Token Accepted via `?token=` URL Query Parameter

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.0-rc.16, the Grav API plugin JwtAuthenticator::extractBearerToken() accepts a JWT from the token URL query parameter on every /api/v1 route, including state-changing endpoints. Request URLs consequently expose valid access tokens through Apache, proxy, and CDN logs, browser history, and Referer headers, allowing a party with access to those records to reuse the token with the owner's API privileges. This issue is fixed in version 1.0.0-rc.16.

Grav API Plugin: Webhook SSRF via Unrestricted cURL Protocols

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, the Grav API plugin WebhookController.php accepts webhook URLs after only FILTER_VALIDATE_URL syntax validation, and WebhookDispatcher.php initializes cURL without CURLOPT_PROTOCOLS or CURLOPT_REDIR_PROTOCOLS restrictions. An account with api.webhooks.write can submit file, dict, gopher, private-network, or link-local targets, retrieve local files and delivery response bodies, and pivot requests to internal services or cloud metadata endpoints. This issue is fixed in version 1.0.6.

Grav API Plugin: Missing authorization on API-key generate/revoke lets any admin.login user forge keys for any account

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.8, the Grav API plugin intercepts the apiKeyGenerate and apiKeyRevoke admin tasks in user/plugins/api/api.php and authorizes the caller with only admin.login. A basic panel user can select another account from the route, create a persistent ApiKeyManager credential bound to that target, and inherit the target's API permissions, including api.super or administrative write access when present. This issue is fixed in version 1.0.8.

grav-plugin-api: Grav API Privilege Escalation to Super Admin

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content, media, configuration, users, and system management. Prior to 1.0.0-beta.15, an insecure direct object reference and logic flaw in the Grav API plugin (UsersController::update) allows any authenticated user with basic API access (api.access) to modify their own permission configuration. An attacker can exploit this to escalate their privileges to Super Administrator (admin.super and api.super), leading to full system compromise and potential RCE. This vulnerability is fixed in 1.0.0-beta.15.
