CVE-2025-68454 WRITEUP HIGH WRITEUP
Craft CMS 4.0.0.1-4.16.16 and 5.0.0-RC1-5.8.20 - Authenticated Remote Code Execution via Twig SSTI
Craft is a platform for creating digital experiences. Versions 5.0.0-RC1 through 5.8.20 and 4.0.0-RC1 through 4.16.16 are vulnerable to potential authenticated Remote Code Execution via Twig SSTI. For this to work, users must have administrator access to the Craft Control Panel, and allowAdminChanges must be enabled, which is against Craft CMS' recommendations for any non-dev environment. Alternatively, a non-administrator account with allowAdminChanges disabled can be used, provided access to the System Messages utility is available. It is possible to craft a malicious payload using the Twig `map` filter in text fields that accept Twig input under Settings in the Craft control panel or using the System Messages utility, which could lead to a RCE. Users should update to the patched versions (5.8.21 and 4.16.17) to mitigate the issue.

CVE-2025-68456 WRITEUP CRITICAL WRITEUP
Craft CMS 3.0.0-4.16.16 and 5.0.0-RC1-5.8.20 - Unauthenticated Resource Exhaustion via Database Backup Trigger
Craft is a platform for creating digital experiences. In versions 5.0.0-RC1 through 5.8.20 and 3.0.0 through 4.16.16, unauthenticated users can trigger database backup operations via specific admin actions, potentially leading to resource exhaustion or information disclosure. Users should update to the patched versions (5.8.21 and 4.16.17) to mitigate the issue. Craft 3 users should update to the latest Craft 4 and 5 releases, which include the fixes.

CVE-2026-25492 WRITEUP MEDIUM WRITEUP
Craft CMS 3.5.0-4.16.17 & 5.0.0-RC1-5.8.21 - Server-Side Request Forgery via GraphQL
Craft CMS is a content management system. In Craft versions 3.5.0 through 4.16.17 and 5.0.0-RC1 through 5.8.21, the save_images_Asset GraphQL mutation can be abused to fetch internal URLs by providing a domain name that resolves to an internal IP address, bypassing hostname validation. When a non-image file extension such as .txt is allowed, downstream image validation is bypassed, which can allow an authenticated attacker with permission to use save_images_Asset to retrieve sensitive data such as AWS instance metadata credentials from the underlying host. This issue is patched in versions 4.16.18 and 5.8.22.

CVE-2026-25493 WRITEUP MEDIUM WRITEUP
Craft CMS saveAsset GraphQL - Redirect-Based Server-Side Request Forgery
Craft is a platform for creating digital experiences. In Craft versions 4.0.0-RC1 through 4.16.17 and 5.0.0-RC1 through 5.8.21, the saveAsset GraphQL mutation validates the initial URL hostname and resolved IP against a blocklist, but Guzzle follows HTTP redirects by default. An attacker can bypass all SSRF protections by hosting a redirect that points to cloud metadata endpoints or any internal IP addresses. This issue is patched in versions 4.16.18 and 5.8.22.

CVE-2026-25494 WRITEUP MEDIUM WRITEUP
Craft CMS saveAsset GraphQL - Alternative IP Server-Side Request Forgery
Craft is a platform for creating digital experiences. In Craft versions 4.0.0-RC1 through 4.16.17 and 5.0.0-RC1 through 5.8.21, the saveAsset GraphQL mutation uses filter_var(..., FILTER_VALIDATE_IP) to block a specific list of IP addresses. However, alternative IP notations (hexadecimal, mixed) are not recognized by this function, allowing attackers to bypass the blocklist and access cloud metadata services. This issue is patched in versions 4.16.18 and 5.8.22.

CVE-2026-25495 WRITEUP HIGH WRITEUP
Craft CMS 4.0.0-4.16.17 and 5.0.0-RC1-5.8.21 - Authenticated SQL Injection via Element Index OrderBy Parameter
Craft is a platform for creating digital experiences. In Craft versions 4.0.0-RC1 through 4.16.17 and 5.0.0-RC1 through 5.8.21, the element-indexes/get-elements endpoint is vulnerable to SQL Injection via the criteria[orderBy] parameter (JSON body). The application fails to sanitize this input before using it in the database query. An attacker with Control Panel access can inject arbitrary SQL into the ORDER BY clause by omitting viewState[order] (or setting both to the same payload). This issue is patched in versions 4.16.18 and 5.8.22.
CVSS 8.8
CVE-2026-25497 WRITEUP HIGH WRITEUP
Craft CMS GraphQL API - Cross-Volume Asset Privilege Escalation
Craft is a platform for creating digital experiences. In Craft versions from 4.0.0-RC1 to before 4.17.0-beta.1 and 5.9.0-beta.1, there is a Privilege Escalation vulnerability in Craft CMS’s GraphQL API that allows an authenticated user with write access to one asset volume to escalate their privileges and modify/transfer assets belonging to any other volume, including restricted or private volumes to which they should not have access. The saveAsset GraphQL mutation validates authorization against the schema-resolved volume but fetches the target asset by ID without verifying that the asset belongs to the authorized volume. This allows unauthorized cross-volume asset modification and transfer. This vulnerability is fixed in 4.17.0-beta.1 and 5.9.0-beta.1.

CVE-2026-25498 WRITEUP HIGH WRITEUP
Craft CMS 4.0.0-4.16.17 and 5.0.0-RC1-5.8.21 - Authenticated Remote Code Execution via Behavior Configuration Injection
Craft is a platform for creating digital experiences. In versions 4.0.0-RC1 through 4.16.17 and 5.0.0-RC1 through 5.8.21, a Remote Code Execution (RCE) vulnerability exists in Craft CMS where the assembleLayoutFromPost() function in src/services/Fields.php fails to sanitize user-supplied configuration data before passing it to Craft::createObject(). This allows authenticated administrators to inject malicious Yii2 behavior configurations that execute arbitrary system commands on the server. This vulnerability represents an unpatched variant of the behavior injection vulnerability addressed in CVE-2025-68455, affecting different endpoints through a separate code path. This vulnerability is fixed in 5.8.22.
