GHSA-qf28-8hc6-vwrp: Payload: Prototype pollution in Payload Import Export plugin
Filed UTCSource GTH ↗
An unauthenticated user could cause unintended application behavior when the Import Export plugin is enabled, allowing an attacker to submit and execute remote code (RCE). Applications that do not use @payloadcms/plugin-import-export are not affected. ### Patches Users should upgrade Payload packages to >= 3.88.0 or >= 4.0.0-canary.27. ### Workarounds Upgrading is recommended. Until then, disable the Import Export plugin or restrict access to its endpoints.
