CVE-2026-105844
Critical · 9.3
CWE-1321 Oct 6, 2026
Payload: Prototype pollution in Payload Import Export plugin
Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.88.0 and canary versions before 4.0.0-canary.27, an unauthenticated user can submit prototype-sensitive field paths when @payloadcms/plugin-import-export is enabled, causing unintended application behavior that can lead to remote code execution. This issue is fixed in versions 3.88.0 and 4.0.0-canary.27.

CWE-862 Oct 6, 2026
Payload: Improper access control for MCP API keys
Payload is a free and open source headless content management system. In @payloadcms/plugin-mcp versions from 3.61.0 until 3.88.0, an authenticated user can manage MCP API keys outside the intended account, enabling privilege escalation through account takeover. This issue is fixed in version 3.88.0.

CWE-200 Oct 6, 2026
Payload: Sort queries could expose protected field information
Payload is a free and open source headless content management system. In versions before 3.88.0 and canary versions before 4.0.0-canary.27, an untrusted user who can query a readable collection, control its sorting, and select a protected field as the sort parameter can infer limited information about field values the user cannot read. This issue is fixed in versions 3.88.0 and 4.0.0-canary.27.

CWE-916 Oct 6, 2026
Payload: Password hashes use insufficient PBKDF2 iterations
Payload is a free and open source headless content management system. Payload versions from 3.0.0 before 3.90.0 and canary versions from 4.0.0-canary.0 before 4.0.0-canary.34 use a lower-than-recommended PBKDF2 work factor for password hashing, reducing the computational effort required to test recovered password hashes. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

CWE-862 Sep 25, 2026
Payload CMS storage-vercel-blob Adapter Improper Access Control on Upload Route
The @payloadcms/storage-vercel-blob storage adapter for Payload contains an improper access control vulnerability that allows authenticated users to bypass collection-level permissions by accessing the client-upload route directly. Attackers can upload files through the client-upload endpoint without possessing the required collection access permissions, circumventing the intended access control enforcement.

CWE-22 Apr 1, 2026
Payload has Insufficient Filename Validation in Client-Upload Signed-URL Endpoints
Payload is a free and open source headless content management system. Prior to version 3.78.0 in @payloadcms/storage-azure, @payloadcms/storage-gcs, @payloadcms/storage-r2, and @payloadcms/storage-s3, the client-upload signed-URL endpoints for S3, GCS, Azure, and R2 did not properly sanitize filenames. An attacker could craft filenames to escape the intended storage location. This issue has been patched in version 3.78.0 for @payloadcms/storage-azure, @payloadcms/storage-gcs, @payloadcms/storage-r2, and @payloadcms/storage-s3.
CVE-2026-34749
Medium · 5.4
CWE-352 Apr 1, 2026
Payload has a CSRF Protection Bypass in Authentication Flow
Payload is a free and open source headless content management system. Prior to version 3.79.1, a Cross-Site Request Forgery (CSRF) vulnerability exists in the authentication flow. Under certain conditions, the configured CSRF protection could be bypassed, allowing cross-site requests to be made. This issue has been patched in version 3.79.1.
CVE-2026-34748
High · 8.7
CWE-79 Apr 1, 2026
@payloadcms/next has Stored XSS in Admin Panel
Payload is a free and open source headless content management system. Prior to version 3.78.0 in @payloadcms/next, a stored Cross-Site Scripting (XSS) vulnerability existed in the admin panel. An authenticated user with write access to a collection could save content that, when viewed by another user, would execute in their browser. This issue has been patched in version 3.78.0.
CVE-2026-34747
High · 8.2
CWE-89 Apr 1, 2026
Payload has an SQL Injection via Query Handling
Payload is a free and open source headless content management system. Prior to version 3.79.1, certain request inputs were not properly validated. An attacker could craft requests that influence SQL query execution, potentially exposing or modifying data in collections. This issue has been patched in version 3.79.1.
CVE-2026-34746
High · 7.7
CWE-918 Apr 1, 2026
Payload has Authenticated SSRF via Upload Functionality
Payload is a free and open source headless content management system. Prior to version 3.79.1, an authenticated Server-Side Request Forgery (SSRF) vulnerability exists in the upload functionality. Authenticated users with create or update access to an upload-enabled collection could cause the server to make outbound HTTP requests to arbitrary URLs. This issue has been patched in version 3.79.1.
CVE-2026-34751
Critical · 9.1
CWE-472 Apr 1, 2026
Payload has Unvalidated Input in Password Recovery Endpoints
Payload is a free and open source headless content management system. Prior to version 3.79.1 in @payloadcms/graphql and payload, a vulnerability in the password recovery flow could allow an unauthenticated attacker to perform actions on behalf of a user who initiates a password reset. This issue has been patched in version 3.79.1 for @payloadcms/graphql and payload.
CVE-2026-27567
Medium · 4.8
CWE-918 Feb 24, 2026
Payload has Server-Side Request Forgery (SSRF) in External File URL Uploads
Payload is a free and open source headless content management system. Prior to 3.75.0, a Server-Side Request Forgery (SSRF) vulnerability exists in Payload's external file upload functionality. When processing external URLs for file uploads, insufficient validation of HTTP redirects could allow an authenticated attacker to access internal network resources. The Payload environment must have at least one collection with `upload` enabled and a user who has `create` access to that upload-enabled collection in order to be vulnerable. An authenticated user with upload collection write permissions could potentially access internal services. Response content from internal services could be retrieved through the application. This vulnerability has been patched in v3.75.0. As a workaround, one may mitigate this vulnerability by disabling external file uploads via the `disableExternalFile` upload collection option, or by restricting `create` access on upload-enabled collections to trusted users only.
CVE-2026-25574
Medium · 5.4
CWE-639 Feb 6, 2026
Payload Affected by Cross-Collection IDOR in payload-preferences Access Control (Multi-Auth Environments)
Payload is a free and open source headless content management system. Prior to 3.74.0, a cross-collection Insecure Direct Object Reference (IDOR) vulnerability exists in the payload-preferences internal collection. In multi-auth collection environments using Postgres or SQLite with default serial/auto-increment IDs, authenticated users from one auth collection can read and delete preferences belonging to users in different auth collections when their numeric IDs collide. This vulnerability has been patched in v3.74.0.
CVE-2026-25544
Critical · 9.8
Public exploit CWE-89 Feb 6, 2026
Payload CMS: SQL Injection via JSON and richText Fields
Payload is a free and open source headless content management system. Prior to 3.73.0, when querying JSON or richText fields, user input was directly embedded into SQL without escaping, enabling blind SQL injection attacks. An unauthenticated attacker could extract sensitive data (emails, password reset tokens) and achieve full account takeover without password cracking. This vulnerability is fixed in 3.73.0.
