Grav 2.0.0-rc.1 through 2.0.21 Configuration Disclosure via print_r
Summary
Grav is a flat-file CMS. In versions 2.0.0-rc.1 through 2.0.21, the Twig content sandbox fails to restrict the dump and serialize filters (print_r, vardump, json_encode, yaml_encode, string): GravExtension::assertSandboxDumpSafe() determines sandbox state by calling SandboxExtension::isSandboxed() without a Source argument, which reports only the global sandbox flag that Grav never enables, so the guard added in GHSA-mc5q-6hpj-rp7j never executes. As a result, an authenticated user with page-edit rights can render {{ config|print_r }} in page content with Twig processing enabled and dump Grav's entire merged configuration — print_r reflects the real Config object held in a private property of the SandboxConfig facade, bypassing its path redaction — exposing plugin secrets such as SMTP credentials, API tokens, webhook secrets and cache backend passwords. Grav 1.7 is not affected because it ships no Twig content sandbox. The issue is fixed in 2.0.22, where the affected filters are registered with Twig's needs_is_sandboxed flag.

Title
Grav through 2.0.21 Unauthenticated Information Disclosure via Clockwork
Summary
Grav is a flat-file CMS. In Grav 1.7.0 through 1.7.53.2 and 2.0.0 through 2.0.21, when the debugger is enabled (system.debugger.enabled: true, which is not the default), the Clockwork profiler endpoint is exposed without authentication: InitializeProcessor::handleDebuggerRequest() intercepts any path containing /__clockwork/ during bootstrap and passes it to Debugger::debuggerRequest(), which performs no user lookup, IP restriction, or Clockwork authenticator check, and also supports anonymous pagination over the entire stored history. With the shipped censored: false default, each stored record contains raw request cookies (including Grav's session cookie, whose value is the PHP session id, allowing an attacker to resume another user's session, including an authenticated admin's), the full parsed request body (Grav's login form posts data[username]/data[password], so passwords are stored in plaintext because Clockwork's password filter only inspects top-level keys), and the site's entire system and plugin configuration, including operator-saved secrets such as SMTP credentials, third-party API keys, and licence keys. Authorization and X-API-Token headers are stored even when censored: true. On Grav 2.0, setting provider: debugbar does not avoid the issue because Grav forces the Clockwork provider for requests preferring a JSON response. The issue is fixed in 1.7.53.4 and 2.0.22, which restrict /__clockwork/ to server-local requests or requests presenting the new system.debugger.token secret and strip cookies and credential headers from stored records. Workarounds include setting debugger.enabled: false or blocking /__clockwork/ at the web server or CDN.

Title
Grav before 2.0.18 Remote Code Execution via sort filter
Summary
Grav before 2.0.18 (affected versions <= 2.0.17) contains a remote code execution vulnerability in the Twig sort filter. The sortFunc wrapper in GravExtension.php hardcodes Twig's isSandboxed argument to false, so unlike |map/|filter/|reduce, |sort accepts a plain function name inside the sandbox; the remaining denylist misses spl_autoload, which performs a PHP include. An authenticated user with only page-write rights (admin.pages or api.pages.write) can supply a crafted payload (e.g., via form frontmatter rendered by the Email plugin) that invokes spl_autoload through the sort filter, resulting in arbitrary PHP execution as the web server user.

Grav Admin Plugin Path Traversal via Save As Language Code
Summary
Grav versions before 1.10.55 contain a path traversal vulnerability in the admin plugin's Save As action that fails to validate the language code parameter. An authenticated admin user with admin.pages.create permission can supply directory traversal sequences in the lang POST field to write arbitrary .md files outside the pages directory with attacker-controlled content.

Title
Grav Form Plugin before 9.1.20 reCAPTCHA v3 Authentication Bypass
Summary
The Grav Form plugin (getgrav/grav-plugin-form) versions 8.0.6 through 9.1.19 select the reCAPTCHA version to validate based solely on which response field key is present in the submitted payload. On a site configured for reCAPTCHA v3, an anonymous attacker can place their v3 token under the v2 field name (g-recaptcha-response instead of token), causing validation to use the v2 branch, which never applies the score threshold or verifies the expected action. This results in a complete bypass of reCAPTCHA v3 bot protection. The issue is fixed in version 9.1.20.

Title
Grav Admin before 2.0.20 Cross-Site Scripting via marked.js
Summary
Grav Admin before 2.0.20 fails to sanitize output from marked.parse() before injecting it into the DOM via Svelte's {@html} directive in MarkdownEditor and MarkdownModal components. Attackers can inject javascript: URI schemes in plugin or theme changelogs to execute arbitrary code in authenticated admin sessions without requiring site access.

Title
Grav Admin before 2.0.21 Stored XSS via username
Summary
Grav Admin (getgrav/grav-plugin-admin2) versions <= 2.0.19 contain a stored cross-site scripting vulnerability in the tHtml() function (src/lib/stores/i18n.svelte.ts), which substitutes untrusted parameters such as usernames into translation templates before parsing the result as markdown. Grav's server-side username validation (DataUser::isValidUsername) blocks filesystem-dangerous characters but not <, >, ", or ', allowing an attacker to register a username containing an HTML payload. When an administrator views a UI surface that renders the username through tHtml()—such as the two-factor force-disable confirmation prompt or the 'page is locked' editor notice—the payload executes in their authenticated session. Fixed in 2.0.21.

Title
Grav 2.0.0 through 2.0.17 Stored XSS via Modular Pages
Summary
Grav versions 2.0.0 through 2.0.17 fail to apply save-time XSS detection to modular pages, allowing authenticated page editors to store Twig-assembled XSS payloads. Attackers with page-edit rights can create modular pages with malicious Twig code that executes in visitor browsers when the parent page is rendered, including in administrator sessions.

Title
Grav before 1.0.18 Authentication Bypass via Scoped API Key
Summary
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.18 does not apply the API-key scope cap in the injectSecurityTab() function of BlueprintController when deciding whether a page's security/permissions blueprint section is editable. Because the function performs raw isSuperAdmin()/hasPermission() checks without a request parameter, it cannot enforce scopeAllows(). A caller holding a scoped API key may therefore see (and potentially edit) page permission fields beyond the scope granted to the key. The end-to-end write-time impact was not fully confirmed by the reporter.

Title
Grav before 1.0.18 Authentication Bypass via Scoped API Key
Summary
The getgrav/grav-plugin-api plugin before 1.0.18 does not enforce API-key scope in the requireNotSuperTarget() function in UsersController.php across seven sensitive user-management endpoints. The check uses isSuperAdmin() on the acting account rather than verifying whether the specific API key carries super authority (via isSuperWithinScope()). As a result, an API key scoped below full super authority but belonging to a super-admin account can act against other super-admin accounts—disabling their 2FA, deleting their avatar, minting new API keys under their identity, or deleting their existing API keys.

Grav before 2.0.16 Information Disclosure via Twig Sandbox
Summary
Grav before 2.0.16 contains an incomplete default denylist in the Twig sandbox configuration that fails to block access to system configuration secrets. Attackers with page-edit permission can use config.get() or config.toArray() in Twig templates to retrieve sensitive values like system.cache.redis.password when config_access is enabled.

Title
Grav before 2.0.16 Information Disclosure via offsetGet
Summary
Grav before 2.0.16 allows sandboxed Twig templates to access sensitive User fields through allow-listed offsetGet() and offsetexists() methods that lack field filtering. Attackers with page-edit permissions can call offsetGet() on User objects to extract hashed passwords and 2FA secrets, enabling offline password cracking and authentication bypass.

Title
Grav before 4.2.2 Remote Code Execution via Email Twig
Summary
The Grav Email plugin (getgrav/grav-plugin-email) before 4.2.2 renders page-editor-controlled Email action parameters as unsandboxed Twig templates. An authenticated remote user with only api.access and api.pages.write permissions can place a Twig expression in header.form.process.email.body, publish the page, and submit the form to execute an arbitrary operating-system command as the account running PHP.

Title
Grav CMS before 2.0.16 Origin Validation Bypass via Referer
Summary
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.

Title
Grav 2.0.0-rc.1 through 2.0.21 Configuration Disclosure via print_r
Summary
Grav is a flat-file CMS. In versions 2.0.0-rc.1 through 2.0.21, the Twig content sandbox fails to restrict the dump and serialize filters (print_r, vardump, json_encode, yaml_encode, string): GravExtension::assertSandboxDumpSafe() determines sandbox state by calling SandboxExtension::isSandboxed() without a Source argument, which reports only the global sandbox flag that Grav never enables, so the guard added in GHSA-mc5q-6hpj-rp7j never executes. As a result, an authenticated user with page-edit rights can render {{ config|print_r }} in page content with Twig processing enabled and dump Grav's entire merged configuration — print_r reflects the real Config object held in a private property of the SandboxConfig facade, bypassing its path redaction — exposing plugin secrets such as SMTP credentials, API tokens, webhook secrets and cache backend passwords. Grav 1.7 is not affected because it ships no Twig content sandbox. The issue is fixed in 2.0.22, where the affected filters are registered with Twig's needs_is_sandboxed flag.

In versions 2.0.0-rc.1 through 2.0.21, the Twig content sandbox fails to restrict the dump and serialize filters (print_r, vardump, json_encode, yaml_encode, string): GravExtension::assertSandboxDumpSafe() determines sandbox state by calling SandboxExtension::isSandboxed() without a Source argument, which reports only the global sandbox flag that Grav never enables, so the guard added in GHSA-mc5q-6hpj-rp7j never executes. As a result, an authenticated user with page-edit rights can render {{ config|print_r }} in page content with Twig processing enabled and dump Grav\u0027s entire merged configuration \u2014 print_r reflects the real Config object held in a private property of the SandboxConfig facade, bypassing its path redaction \u2014 exposing plugin secrets such as SMTP credentials, API tokens, webhook secrets and cache backend passwords. Grav 1.7 is not affected because it ships no Twig content sandbox. The issue is fixed in 2.0.22, where the affected filters are registered with Twig\u0027s needs_is_sandboxed flag."

Title
Grav through 2.0.21 Unauthenticated Information Disclosure via Clockwork
Summary
Grav is a flat-file CMS. In Grav 1.7.0 through 1.7.53.2 and 2.0.0 through 2.0.21, when the debugger is enabled (system.debugger.enabled: true, which is not the default), the Clockwork profiler endpoint is exposed without authentication: InitializeProcessor::handleDebuggerRequest() intercepts any path containing /__clockwork/ during bootstrap and passes it to Debugger::debuggerRequest(), which performs no user lookup, IP restriction, or Clockwork authenticator check, and also supports anonymous pagination over the entire stored history. With the shipped censored: false default, each stored record contains raw request cookies (including Grav's session cookie, whose value is the PHP session id, allowing an attacker to resume another user's session, including an authenticated admin's), the full parsed request body (Grav's login form posts data[username]/data[password], so passwords are stored in plaintext because Clockwork's password filter only inspects top-level keys), and the site's entire system and plugin configuration, including operator-saved secrets such as SMTP credentials, third-party API keys, and licence keys. Authorization and X-API-Token headers are stored even when censored: true. On Grav 2.0, setting provider: debugbar does not avoid the issue because Grav forces the Clockwork provider for requests preferring a JSON response. The issue is fixed in 1.7.53.4 and 2.0.22, which restrict /__clockwork/ to server-local requests or requests presenting the new system.debugger.token secret and strip cookies and credential headers from stored records. Workarounds include setting debugger.enabled: false or blocking /__clockwork/ at the web server or CDN.

Title
Grav before 2.0.18 Remote Code Execution via sort filter
Summary
Grav before 2.0.18 (affected versions <= 2.0.17) contains a remote code execution vulnerability in the Twig sort filter. The sortFunc wrapper in GravExtension.php hardcodes Twig's isSandboxed argument to false, so unlike |map/|filter/|reduce, |sort accepts a plain function name inside the sandbox; the remaining denylist misses spl_autoload, which performs a PHP include. An authenticated user with only page-write rights (admin.pages or api.pages.write) can supply a crafted payload (e.g., via form frontmatter rendered by the Email plugin) that invokes spl_autoload through the sort filter, resulting in arbitrary PHP execution as the web server user.

Grav Admin Plugin Path Traversal via Save As Language Code
Summary
Grav versions before 1.10.55 contain a path traversal vulnerability in the admin plugin's Save As action that fails to validate the language code parameter. An authenticated admin user with admin.pages.create permission can supply directory traversal sequences in the lang POST field to write arbitrary .md files outside the pages directory with attacker-controlled content.

Title
Grav Form Plugin before 9.1.20 reCAPTCHA v3 Authentication Bypass
Summary
The Grav Form plugin (getgrav/grav-plugin-form) versions 8.0.6 through 9.1.19 select the reCAPTCHA version to validate based solely on which response field key is present in the submitted payload. On a site configured for reCAPTCHA v3, an anonymous attacker can place their v3 token under the v2 field name (g-recaptcha-response instead of token), causing validation to use the v2 branch, which never applies the score threshold or verifies the expected action. This results in a complete bypass of reCAPTCHA v3 bot protection. The issue is fixed in version 9.1.20.

Title
Grav Admin before 2.0.20 Cross-Site Scripting via marked.js
Summary
Grav Admin before 2.0.20 fails to sanitize output from marked.parse() before injecting it into the DOM via Svelte's {@html} directive in MarkdownEditor and MarkdownModal components. Attackers can inject javascript: URI schemes in plugin or theme changelogs to execute arbitrary code in authenticated admin sessions without requiring site access.

Title
Grav Admin before 2.0.21 Stored XSS via username
Summary
Grav Admin (getgrav/grav-plugin-admin2) versions <= 2.0.19 contain a stored cross-site scripting vulnerability in the tHtml() function (src/lib/stores/i18n.svelte.ts), which substitutes untrusted parameters such as usernames into translation templates before parsing the result as markdown. Grav's server-side username validation (DataUser::isValidUsername) blocks filesystem-dangerous characters but not <, >, ", or ', allowing an attacker to register a username containing an HTML payload. When an administrator views a UI surface that renders the username through tHtml()—such as the two-factor force-disable confirmation prompt or the 'page is locked' editor notice—the payload executes in their authenticated session. Fixed in 2.0.21.

Title
Grav 2.0.0 through 2.0.17 Stored XSS via Modular Pages
Summary
Grav versions 2.0.0 through 2.0.17 fail to apply save-time XSS detection to modular pages, allowing authenticated page editors to store Twig-assembled XSS payloads. Attackers with page-edit rights can create modular pages with malicious Twig code that executes in visitor browsers when the parent page is rendered, including in administrator sessions.

Title
Grav before 1.0.18 Authentication Bypass via Scoped API Key
Summary
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.18 does not apply the API-key scope cap in the injectSecurityTab() function of BlueprintController when deciding whether a page's security/permissions blueprint section is editable. Because the function performs raw isSuperAdmin()/hasPermission() checks without a request parameter, it cannot enforce scopeAllows(). A caller holding a scoped API key may therefore see (and potentially edit) page permission fields beyond the scope granted to the key. The end-to-end write-time impact was not fully confirmed by the reporter.

Title
Grav before 1.0.18 Authentication Bypass via Scoped API Key
Summary
The getgrav/grav-plugin-api plugin before 1.0.18 does not enforce API-key scope in the requireNotSuperTarget() function in UsersController.php across seven sensitive user-management endpoints. The check uses isSuperAdmin() on the acting account rather than verifying whether the specific API key carries super authority (via isSuperWithinScope()). As a result, an API key scoped below full super authority but belonging to a super-admin account can act against other super-admin accounts—disabling their 2FA, deleting their avatar, minting new API keys under their identity, or deleting their existing API keys.
