Title
Low privilege condition filter escapes Twig sandbox, recovers "securityKey" and reaches RCE
Summary
Craft CMS allows any authenticated control panel user to submit an element-search condition whose element selector is evaluated as a sandboxed Twig object template. Craft’s allowed column filter delegates property lookup to Yii ArrayHelper, outside Twig’s SecurityPolicy. Repeated single-segment lookups therefore bypass the sandbox’s empty property/method allowlists.
The vulnerable condition value is ultimately cast to an integer. That does not protect the secret: the template can return author ID 1 when a guessed key character is correct and an impossible ID otherwise. The JSON endpoint returns entries for the first case and an empty array for the second, forming a stable remote character oracle.
After recovering GeneralConfig::securityKey, the same user can compute Craft’s generic HMAC wire format offline. Signed parameters such as redirect are then accepted and passed to unsandboxed View::renderObjectTemplate(), where Twig’s string-callable form can invoke native PHP callables. The regression proof uses the harmless substr() callback and observes abcdef becoming cdef; it does not execute an OS command.

Title
Unauthenticated payment reuse allows unpaid orders to be marked as paid
Summary
The Mollie webhook endpoint accepts two independent, attacker-controlled parameters and never verifies that they belong together:
* commerceTransactionHash — selects which Craft Commerce transaction is completed
* id — selects which Mollie payment is queried for its status
An unauthenticated attacker holding any paid Mollie payment ID from the merchant’s account can pair it with any transaction hash.
Commerce queries Mollie, sees status: paid, and marks the target transaction successful for that transaction’s full
amount, regardless of how much was actually paid.

Title
Control panel only API response emulation replaces "securityKey" and reaches server RCE
Summary
The app/process-api-response-headers action accepts fake Craft API response headers from any authenticated control panel user.
A non-admin user with only accessCp can place newline characters in X-Craft-Plugin-Licenses. Craft passes this value to its .env writer without removing the newlines.
This lets the user insert a new attacker-known CRAFT_SECURITY_KEY into .env. After Craft loads that key, the user can forge a signed login redirect containing a Twig system() callback.
This is different from the previous report. That report reads the existing key through a Twig sandbox bypass. This report replaces the key through fake API headers and CRLF injection. Fixing either source does not fix the other.

Title
Craft CMS before 4.18.8 and 5.11.0 Twig create() Blocklist Bypass Leading to RCE
Summary
Craft CMS 4.x before 4.18.8 and 5.x before 5.11.0 contains a blocklist bypass in the Twig create() function because its class-name checks are case-sensitive while PHP class resolution is not. Attackers with template-execution rights, such as Control Panel administrators, can instantiate SplFileObject via a lowercase class name to read .env secrets or write a PHP file into the webroot for remote code execution.

Title
Craft CMS before 4.18.8 and 5.11.0 Twig Sandbox Allowlist Bypass via Array Filters
Summary
Craft CMS 4.0.0 before 4.18.8 and 5.0.0 before 5.11.0 contains a Twig sandbox allowlist bypass because the column, contains, filterByValue, index, where, and multisort filters resolve caller-supplied keys via ArrayHelper::getValue() without consulting the sandbox security policy. Authenticated Control Panel users can supply dot-path keys to traverse the craft global and disclose the securityKey, database credentials, and auth tokens.

Title
Craft CMS before 4.18.8 and 5.11.0 Authenticated RCE via Twig group Filter Array-Callable
Summary
Craft CMS 4.x before 4.18.8 and 5.x before 5.11.0 contains a remote code execution vulnerability in the Twig group filter, which invokes non-string arrow arguments as callables without the checkArrow guard used by other arrow-accepting filters. Authenticated control panel users can pass an array-callable such as FileHelper::writeToFile via element-select condition rules to write a webshell to the webroot and execute code as the web user.

Title
Craft CMS 4.0.0 before 4.18.7 and 5.0.0 before 5.10.14 RCE via actionCacheUpdates Behavior Injection
Summary
Craft CMS 4.0.0 before 4.18.7 and 5.0.0 before 5.10.14 passes the raw 'updates' request parameter in AppController::actionCacheUpdates to UpdatesModel without Component::cleanseConfig(), allowing behavior and event-handler injection. Authenticated control panel users with the performUpdates permission or Updates-utility access can supply 'as' or 'on' keys, such as an AttributeTypecastBehavior gadget, to execute arbitrary code.

Title
Craft CMS 5.0.0 before 5.10.14 DOM XSS via returnUrl in 2FA Verification
Summary
Craft CMS 5.0.0 before 5.10.14 contains a DOM-based cross-site scripting vulnerability in the control panel login and 2FA verification flow, where a user-controlled returnUrl accepting javascript: URLs is used in client-side navigation. Attackers can lure a 2FA-enabled victim into opening a crafted /admin/login?verify=1 URL between password submission and TOTP verification, executing JavaScript in the authenticated control panel with the victim's permissions.

Title
Craft CMS 5.0.0 before 5.10.14 Missing Authorization via app/switch-to-licensed-edition
Summary
Craft CMS from 5.0.0 before 5.10.14 contains a missing authorization vulnerability in AppController::actionSwitchToLicensedEdition() that lets any authenticated user change the installed edition. Low-privileged front-end users can call the action route when the licensed edition mismatches to persistently downgrade the site edition in project config, which admins cannot reverse from the control panel.

Title
Craft CMS 4.0.0 before 4.18.7 and 5.0.0 before 5.10.14 Arbitrary File Read via Twig create() DOMDocument
Summary
Craft CMS 4.0.0 before 4.18.7 and 5.0.0 before 5.10.14 contains an arbitrary file read vulnerability because the Twig create() class blocklist does not cover DOMDocument. Attackers able to set an entry-type title format, including via project-config/apply, can use create('DOMDocument').loadHTMLFile() with textContent to expose local file contents to non-admin users who can view entries.

Title
Low privilege condition filter escapes Twig sandbox, recovers "securityKey" and reaches RCE
Summary
Craft CMS allows any authenticated control panel user to submit an element-search condition whose element selector is evaluated as a sandboxed Twig object template. Craft’s allowed column filter delegates property lookup to Yii ArrayHelper, outside Twig’s SecurityPolicy. Repeated single-segment lookups therefore bypass the sandbox’s empty property/method allowlists.
The vulnerable condition value is ultimately cast to an integer. That does not protect the secret: the template can return author ID 1 when a guessed key character is correct and an impossible ID otherwise. The JSON endpoint returns entries for the first case and an empty array for the second, forming a stable remote character oracle.
After recovering GeneralConfig::securityKey, the same user can compute Craft’s generic HMAC wire format offline. Signed parameters such as redirect are then accepted and passed to unsandboxed View::renderObjectTemplate(), where Twig’s string-callable form can invoke native PHP callables. The regression proof uses the harmless substr() callback and observes abcdef becoming cdef; it does not execute an OS command.

Title
Unauthenticated payment reuse allows unpaid orders to be marked as paid
Summary
The Mollie webhook endpoint accepts two independent, attacker-controlled parameters and never verifies that they belong together:
* commerceTransactionHash — selects which Craft Commerce transaction is completed
* id — selects which Mollie payment is queried for its status
An unauthenticated attacker holding any paid Mollie payment ID from the merchant’s account can pair it with any transaction hash.
Commerce queries Mollie, sees status: paid, and marks the target transaction successful for that transaction’s full
amount, regardless of how much was actually paid.

Title
Control panel only API response emulation replaces "securityKey" and reaches server RCE
Summary
The app/process-api-response-headers action accepts fake Craft API response headers from any authenticated control panel user.
A non-admin user with only accessCp can place newline characters in X-Craft-Plugin-Licenses. Craft passes this value to its .env writer without removing the newlines.
This lets the user insert a new attacker-known CRAFT_SECURITY_KEY into .env. After Craft loads that key, the user can forge a signed login redirect containing a Twig system() callback.
This is different from the previous report. That report reads the existing key through a Twig sandbox bypass. This report replaces the key through fake API headers and CRLF injection. Fixing either source does not fix the other.

Title
Craft CMS before 4.18.8 and 5.11.0 Twig create() Blocklist Bypass Leading to RCE
Summary
Craft CMS 4.x before 4.18.8 and 5.x before 5.11.0 contains a blocklist bypass in the Twig create() function because its class-name checks are case-sensitive while PHP class resolution is not. Attackers with template-execution rights, such as Control Panel administrators, can instantiate SplFileObject via a lowercase class name to read .env secrets or write a PHP file into the webroot for remote code execution.

Craft CMS 5.0.0 before 5.11.0 Verification Code Reuse via users/set-password
Summary
Craft CMS from 5.0.0 before 5.11.0 contains an authentication bypass vulnerability that allows attackers to reuse verification codes because users/verify-email does not invalidate them for active users. Attackers who obtain a victim's emailed code can submit it to users/set-password after the victim verifies an email change, resetting the password and taking over the account.

Title
Craft CMS before 4.18.8 and 5.11.0 Twig Sandbox Allowlist Bypass via Array Filters
Summary
Craft CMS 4.0.0 before 4.18.8 and 5.0.0 before 5.11.0 contains a Twig sandbox allowlist bypass because the column, contains, filterByValue, index, where, and multisort filters resolve caller-supplied keys via ArrayHelper::getValue() without consulting the sandbox security policy. Authenticated Control Panel users can supply dot-path keys to traverse the craft global and disclose the securityKey, database credentials, and auth tokens.

Title
Craft CMS before 4.18.8 and 5.11.0 Authenticated RCE via Twig group Filter Array-Callable
Summary
Craft CMS 4.x before 4.18.8 and 5.x before 5.11.0 contains a remote code execution vulnerability in the Twig group filter, which invokes non-string arrow arguments as callables without the checkArrow guard used by other arrow-accepting filters. Authenticated control panel users can pass an array-callable such as FileHelper::writeToFile via element-select condition rules to write a webshell to the webroot and execute code as the web user.

Title
Craft CMS 4.0.0 before 4.18.7 and 5.0.0 before 5.10.14 RCE via actionCacheUpdates Behavior Injection
Summary
Craft CMS 4.0.0 before 4.18.7 and 5.0.0 before 5.10.14 passes the raw 'updates' request parameter in AppController::actionCacheUpdates to UpdatesModel without Component::cleanseConfig(), allowing behavior and event-handler injection. Authenticated control panel users with the performUpdates permission or Updates-utility access can supply 'as' or 'on' keys, such as an AttributeTypecastBehavior gadget, to execute arbitrary code.

Title
Craft CMS 5.0.0 before 5.10.14 DOM XSS via returnUrl in 2FA Verification
Summary
Craft CMS 5.0.0 before 5.10.14 contains a DOM-based cross-site scripting vulnerability in the control panel login and 2FA verification flow, where a user-controlled returnUrl accepting javascript: URLs is used in client-side navigation. Attackers can lure a 2FA-enabled victim into opening a crafted /admin/login?verify=1 URL between password submission and TOTP verification, executing JavaScript in the authenticated control panel with the victim's permissions.

Title
Craft CMS 5.0.0 before 5.10.14 Missing Authorization via app/switch-to-licensed-edition
Summary
Craft CMS from 5.0.0 before 5.10.14 contains a missing authorization vulnerability in AppController::actionSwitchToLicensedEdition() that lets any authenticated user change the installed edition. Low-privileged front-end users can call the action route when the licensed edition mismatches to persistently downgrade the site edition in project config, which admins cannot reverse from the control panel.
