Parse Server before 8.6.107 and 9.0.0 before 9.10.5-alpha.8 Information Disclosure via beforeSave Reverted Fields

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.

Parse Server before 8.6.107 and 9.0.0 before 9.10.5-alpha.8 returns the stored value of a field reverted by a beforeSave trigger in object update responses, even to clients without read access to that object or field. An authenticated client able to update an object whose beforeSave trigger reverts a field, via revert() or a constant: true validator, can read protected values, including its own account's raw MFA authData when protectedFieldsTriggerExempt is enabled.
