CVE-2026-72783: Improper Limitation of a Pathname to a Restricted Directory

Craft CMS versions = 5.0.0-RC1 before 5.10.6 and = 4.0.0-RC1 before 4.18.2 contain a theoretical path traversal weakness in the ensurePathIsContained function of the Local file system class. The order of operations validates the path before normalization, so normalization could invalidate prior...

CVE-2026-72782: Exposure of Resource to Wrong Sphere

Craft CMS versions = 5.0.0-RC1 before 5.10.6 and = 4.0.0-RC1 before 4.18.2 interpolate environment variables and secrets via $ENVVAR strings in the elementId parameter into Twig templates before rendering, even when the Twig sandbox is enabled. An authenticated attacker with control panel access...

CVE-2026-72778: Improperly Controlled Modification of Dynamically-Determined Object Attributes

Craft CMS versions from 4.0.0-RC1 before 4.18.2 and from 5.0.0-RC1 before 5.10.6 contain an authenticated remote code execution vulnerability in the control panel element-search condition handling. Craft cleanses the outer request-controlled condition array via Component::cleanseConfig, but...

CVE-2026-72780: Authentication Bypass by Capture-replay

Craft CMS before 5.10.5 fails to persist updated credential counters after WebAuthn assertion validation in the passkey login endpoint. Attackers can replay captured login request bodies containing requestOptions and response to create additional authenticated sessions for victim accounts...

Craft CMS versions = 5.0.0-RC1 before 5.10.6 and = 4.0.0-RC1 before 4.18.2 contain a server-side request forgery vulnerability in the GraphQL saveAsset mutation, which fetches an attacker-supplied URL server-side. The anti-SSRF validation is incomplete: validateIp does not cover CGNAT 100.64.0.0/...

CVE-2026-72784: Server-Side Request Forgery (SSRF)

Craft CMS versions = 5.0.0-RC1 before 5.10.6 and = 4.0.0-RC1 before 4.18.2 contain a server-side request forgery vulnerability in the GraphQL save Asset mutation, which fetches an attacker-supplied URL server-side. The anti-SSRF validation is incomplete: validateIp does not cover CGNAT...

CVE-2026-72785: Incorrect Authorization

Craft CMS 5.0.0-RC1 through 5.10.5 contains an incorrect authorization vulnerability. A control-panel user holding only the viewCategories permission without saveCategories for a category group can permanently modify that group's category structure — reordering and re-parenting categories — via t...

CVE-2026-72781: Protection Mechanism Failure

Craft CMS versions = 5.0.0-RC1 before 5.10.7 and = 4.0.0-RC1 before 4.18.3 contain a remote code execution vulnerability in the Twig sandbox mechanism. Because Craft marks the ElementInterface as safe via the AllowedInSandbox attribute and the sandbox allowlisting extends to the entire class...

Replay Attack

Overview craftcms/cms is a content management system. Affected versions of this package are vulnerable to Replay Attack through the users/login-with-passkey process. An attacker can gain unauthorized access to user accounts by replaying a previously captured passkey login request body, as the...

Craft CMS: Passkey login accepts replayed WebAuthn assertions

Craft CMS passkey login accepts WebAuthn requestOptions from the unauthenticated login request body and does not persist the updated credential counter returned by the WebAuthn assertion validator. A captured passkey login request body can therefore be replayed because the old challenge is accept...

Craft CMS: Arbitrary file read via SplFileObject in non-sandboxed template contexts

The create Twig function introduced in 5.9.0 allows instantiation of arbitrary PHP classes from template code, restricted only by a 5-entry blocklist. SplFileObject is not in the blocklist, enabling arbitrary file read, including .env security key, DB credentials and the passwd file from...

Incomplete List of Disallowed Inputs

Overview craftcms/cms is a content management system. Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the create function in non-sandboxed template contexts. An attacker can access arbitrary files on the server filesystem by instantiating SplFileObject...

GHSA-596P-6JV8-775V Craft CMS: Authenticated leak of secret environment variables

Environment variables and secrets are interpolated into a Twig template even when the Twig sandbox is enabled, allowing them to be leaked by an authenticated attacker. The Craft vulnerability CVE-2026-31857 was only patched by applying sandboxed Twig templating. This theoretically protects Craft...
