Payload authentication token field handling issue

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

Payload is a free and open source headless content management system. In versions after 3.0.0 and before 3.90.0, a custom field option that maps a field to a reserved authentication claim name can place unintended values in the authentication token issued at login. This issue is fixed in version 3.90.0.

### Impact Under certain field configurations, Payload could include unintended values in the authentication token issued at login. You are affected if: - You use an affected Payload version and have configured a custom field option that maps a field to a reserved authentication claim name. ### Patches Payload now restricts which field configuration options can influence the contents of the authentication token. Users should upgrade payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`. ### Workarounds There is no complete workaround. Users should upgrade payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
