CVE-2026-126294

Grav Login Plugin before 3.11.0 Two-Factor Authentication Bypass via /login

Grav Login plugin before 3.11.0 contains an authentication bypass vulnerability that allows attackers with an account password to skip two-factor verification when the global twofa_enabled setting is off. Attackers can sign in through the /login form, remember-me cookie, or magic link to obtain a session the API plugin accepts, gaining full account permissions including super-admin control.

Grav Lightbox Gallery 1.1.0 before 1.3.2 File Read via Shortcode Media Actions

Grav Lightbox Gallery plugin 1.1.0 before 1.3.2 on Grav 2.x calls any medium method named in image, thumb or thumb_options shortcode values without core's allowed media action check. A page editor can chain addMetaFile with value, toYaml or toJson to read server-readable YAML files, such as account password hashes, 2FA secrets and API keys, into a publicly viewable page.

Grav 2.0.0 before 2.2.5 Unauthorized Page Deletion via Flex Form Directives

Grav from 2.0.0 before 2.2.5 contains an improper access control vulnerability in FlexDirectory::dynamicFlexField() that allows page authors to call arbitrary Flex object methods via flex-*@ directives in page frontmatter. When a user with page edit rights opens the page, directives calling setStorageKey() and delete() run in their session, deleting protected pages neither account may delete.

Grav from 1.7.53.3 before 1.7.53.6 Clockwork Profiler Authorization Bypass via Loopback Fallback

Grav from 1.7.53.3 before 1.7.53.6 contains an authorization bypass in Debugger::isDebuggerRequestAuthorized() that allows unauthenticated visitors to read /__clockwork/ profiler data via a loopback REMOTE_ADDR fallback. Behind a same-host reverse proxy, remote requests appear as loopback, letting attackers read stored records including administrator plaintext passwords and configuration credentials.

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-2026-72832

Grav before 2.0.13 Stored XSS via quoted-attribute bypass

Grav versions from 1.5.2 through 2.0.12 contain a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). The event-handler scan is anchored at `<` and uses `[^>]*?`, which cannot cross the first literal `>`; when a `>` appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as `<img src=x title=">" onerror=alert(document.domain)>`, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page. Fixed in 2.0.13.

CVE-2026-72831

Grav through 2.0.11 Authentication Bypass via Flex Objects

The Flex Objects plugin (through 1.4.6, tested with Grav 2.0.11) contains an incorrect authorization vulnerability in its Flex Objects API. FlexApiController::update() checks only the general Flex directory permission and does not apply the additional target/field/super-admin checks enforced by the dedicated Users and Groups API controllers. An authenticated account with api.access, admin.login, and users.update permissions (but without api.users.write or admin.super) can use the generic /api/v1/flex-objects/user-accounts endpoint to change a super administrator's password, or the /api/v1/flex-objects/user-groups endpoint to grant its group admin.super, resulting in full site takeover. Fixed in Flex Objects 1.4.7.

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).

CVE-2026-61451

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-plugin-admin is the admin plugin for Grav is an HTML user interface that provides a convenient way to configure Grav and easily create and modify pages. Prior to 1.10.49.5, the application fails to properly validate and sanitize user input in the data[header][title] parameter. As a result, attackers can craft a malicious URL with an XSS payload. When this URL is accessed, the injected script is reflected back in the HTTP response and executed within the context of the victim's browser session. This vulnerability is fixed in 1.10.49.5.

The Grav API plugin (getgrav/grav-plugin-api) before 1.0.3 fails to sanitize SVG files uploaded through the POST /api/v1/media endpoint. The HandlesMediaUploads::processUploadedFile() method validates only the file extension and never invokes Security::sanitizeSVG(), so an authenticated attacker with the api.media.write permission can upload an SVG containing arbitrary JavaScript. The file is stored unmodified and served with Content-Type: image/svg+xml; when an administrator opens it in a browser (directly or via <object>/<iframe>), the embedded script executes in their session context, enabling cookie theft and session hijacking.
