Prototype Pollution

SandboxJS is vulnerable to Prototype Pollution. The vulnerability is due to improper handling of the isGlobal protection flag, where wrapping a host global prototype in an array strips its taint and allows sandboxed code to mutate host built-in prototypes, leading to prototype pollution and...

CVE-2026-25493

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 bypa...

CVE-2026-25494

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 filtervar..., FILTERVALIDATEIP to block a specific list of IP addresses. However, alternative IP notations hexadecimal, mixed are not...

@nyariv/sandboxjs has host prototype pollution from sandbox via array intermediary (sandbox escape)

Summary A sandbox escape vulnerability allows sandboxed code to mutate host built-in prototypes by laundering the isGlobal protection flag through array literal intermediaries. When a global prototype reference e.g., Map.prototype, Set.prototype is placed into an array and retrieved, the isGlobal...

GHSA-FXP3-G6GW-4R4V Craft CMS: GraphQL Asset Mutation Privilege Escalation

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...

Craft CMS Vulnerable to SSRF in GraphQL Asset Mutation via Alternative IP Notation

I observed a recent commit intended to mitigate Server-Side Request Forgery SSRF vulnerabilities. While the implemented defense mechanisms are an improvement, I have identified two methods to bypass these protections. This report details the first bypass method involving alternative IP notation,...

Server-side Request Forgery (SSRF)

Overview craftcms/cms is a content management system. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the saveAsset GraphQL mutation validates the initial URL hostname and resolved IP against a blocklis. An attacker can access internal resources or sensiti...

GHSA-8JR8-7HR4-VHFX Craft CMS Vulnerable to SSRF in GraphQL Asset Mutation via HTTP Redirect

Summary 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. ---...

Craft CMS: save_images_Asset graphql mutation can be abused to exfiltrate AWS credentials of underlying host

Summary - The saveimagesAsset graphql mutation allows a user to give a url of an image to download. Url must use a domain, not a raw IP. - Attacker sets up domain attacker.domain with an A record of something like 169.254.169.254 special AWS metadata IP - Attacker invokes saveimagesAsset with url...

Server-side Request Forgery (SSRF)

Overview craftcms/cms is a content management system. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF in handleUpload, which is exploitable via the saveimagesAsset mutation in the GraphQL API. An attacker can retrieve sensitive internal resources, such as AWS...
