Grav Login OAuth Plugin before 1.4.3 Predictable Local Credentials Authentication Bypass

Grav Login OAuth plugin (grav-plugin-login-oauth) before 1.4.3 provisions OAuth accounts as ordinary Grav users with a deterministic <provider>.<id> username and an unsalted MD5 hash of the provider identifier as the password, without disabling password login. Unauthenticated remote attackers who learn or guess a provider identifier can reproduce these credentials and log in, gaining administrative control of privileged accounts.

Grav Login Plugin 2.7.0 before 3.9.9 2FA Bypass via Profile Update Form

Grav Login plugin 2.7.0 before 3.9.9 contains an authentication bypass in processUserProfile(), which checks that the session user exists but not that a pending front-end 2FA session is fully authorized. Attackers with a victim's password who can publish a page form without an access rule can invoke update_user before completing 2FA to disable twofa_enabled and take over the account.

Grav before 2.0.14 Stored XSS via Invalid UTF-8 Byte

Grav before 2.0.14 contains a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). All XSS detection patterns use the PCRE /u (UTF-8) modifier, so a single invalid UTF-8 byte anywhere in page content causes preg_match() to return false for every pattern, silently bypassing the save-time XSS safety gate (Validation::checkSafety()). An authenticated attacker with page-edit permissions (without the security.xss_whitelist privilege) can store malicious JavaScript that executes in the browser of a visitor who views the affected page.

Grav CMS before 2.0.16 Origin Validation Bypass via Referer

Grav CMS before 2.0.16 contains an origin validation bypass in the Uri::referrer() and Pages::referrerRoute() methods, which validate the Referer header using an unanchored string prefix match (str_starts_with($referrer, $base)) with no trailing delimiter. An attacker who controls a domain that begins with the victim site's origin (e.g. https://example.com.attacker.tld) can send a request with such a Referer to be treated as same-origin, bypassing the Referer-based origin check.

Grav before 2.0.2 Config Exfiltration via offsetGet Filter

Grav before 2.0.2 contains a Twig sandbox bypass that allows a page author (any admin.pages user, or anyone able to write to user/pages) to exfiltrate configuration secrets. Although the sandbox replaces the 'config' variable with a redacted facade and strips Config::get/toArray from the method allowlist, the raw container remains accessible via the allow-listed grav.offsetGet('config'), which returns the real Config object. Allow-listed object-dumping filters (json_encode, print_r, yaml_encode) then serialize that object at the PHP level without invoking the sandbox method gate, exposing the full config tree including plugin secrets such as SMTP credentials, API keys, and plugin DB credentials. This is an incomplete fix for GHSA-j274-39qw-32c9.

Grav CMS Scheduler Webhook Authentication Bypass via Null Short-Circuit

Grav CMS's scheduler-webhook plugin contains an authentication bypass in the webhook token check. When the webhook feature is enabled but no webhookToken is configured, a compound conditional short-circuits and skips token validation, so an unauthenticated remote attacker who can reach POST /scheduler/webhook can trigger the operator's already-configured scheduled jobs by sending a single request. The primitive is triggering-existing-jobs, not attacker-chosen command execution: the attacker controls when the jobs run and which one runs (via ?job=), but does not control what the jobs do. Code execution follows only when the operator has configured a job that shells out, and even then the attacker controls timing rather than payload. Not a default-install issue: reaching the endpoint requires the separate scheduler-webhook GPM plugin to be installed, scheduler.modern.webhook.enabled to be true (default false), and no webhookToken to be configured; a stock Grav or Grav-Admin install exposes nothing here.

Grav Data Manager before 1.4.5 Stored XSS via item-detail view

The Grav Data Manager plugin (getgrav/grav-plugin-datamanager) versions 1.0.1 through 1.4.4 render stored data entries in the item-detail view (admin/templates/partials/item.html.twig) without escaping, applying Twig's `raw` filter — in some cases after a striptags('<br>') call that PHP's strip_tags() bypasses by preserving allowed tags together with their attributes. An unauthenticated visitor who submits a front-end form whose submissions are saved to user/data can store an HTML payload that executes as JavaScript in the session and origin of an administrator who later opens that entry in the classic admin panel, running with that administrator's privileges and CSRF token. Execution occurs without further interaction for list values (such as checkbox or multi-select fields) and on hover for ordinary text fields. Sites using the Grav 2.0 Admin Next interface are not affected, because it renders the same data through a separate, correctly escaping code path. The issue is fixed in Data Manager 1.4.5.
