Impact A user can submit a request that exploits a SQL Injection vulnerability in Payload.
You are affected if: - You use an affected Payload version. - Untrusted users can query readable collections using dynamic filters or joins.
You are not affected if you use MongoDB (@payloadcms/mongodb).
Patches Users should upgrade Payload packages to >= 3.88.0 or >= 4.0.0-canary.27.
Workarounds Upgrading to a patched version is recommended. Until you can upgrade, restrict untrusted users from supplying dynamic query filters or join parameters and limit read access to affected collections.
Impact
A readable collection could expose information about protected documents in a related collection.
You are affected if:
- You expose a readable collection with a relationship to a collection protected by access.read where constraints.
Patches
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Workarounds
There is no complete workaround. Upgrade Payload packages >= 3.90.0 or >= 4.0.0-canary.34.
Impact
A user with query access could use polymorphic join filters to infer hidden or read-restricted field values, including password-reset tokens.
You are affected if:
- You use an affected Payload version. - Users can query a collection with a polymorphic join to sensitive fields.
Patches
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Workarounds
There is no complete workaround. Restricting read access to sensitive collections reduces exposure but does not replace upgrading.
Impact Under certain conditions, an attacker can craft a redirect link that sends a guest user to an untrusted destination after authenticating.
Patches Users should upgrade Payload packages to >= 3.88.0 or >= 4.0.0-canary.27.
Workarounds Upgrading is recommended. Until then, remove user-controlled redirect values from authentication flows or restrict them to known local paths.
Impact
Payload's duplicate operation copies field values from the source document even when a field is hidden, or its access.read or access.create rule would reject the value for that caller.
The disableDuplicate collection setting, enabled by default on auth collections, did not stop this.
Patches
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Workarounds
Add a beforeDuplicate field hook to fields and set the value to empty or your default value.
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, a crafted request to the public first-register operation can execute code remotely when local authentication is enabled and no initial user has been created. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, a collection that allows downloadable SVG uploads can store a malicious SVG that bypasses sanitization and executes attacker-controlled JavaScript when a user downloads and opens the SVG. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an authenticated user who can update or delete uploads stored locally can cause file cleanup to remove unintended files outside the configured upload directory, resulting in data loss or service disruption. Deployments that restrict upload management to trusted users are less exposed. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, local upload configurations that accept XML files can store an XML file and stylesheet that execute JavaScript in the Payload origin when a logged-in user opens the file. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
