ash is vulnerable to Incorrect Authorization
59
Medium Risk
This Affects:
ashTL;DR
A logic error in the policy authorizer's runtime check handling puts records in the wrong branch once result state is populated. After the first record, rows whose policy scenarios are all impossible are treated as authorized and left in the results. Resources that use runtime checks leak denied records beyond the first row in multi-record reads. The fix forbids records whose policy scenarios are all impossible.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your resources use runtime (non-strict) policy checks on read actions.
Background info
ash is vulnerable to Incorrect Authorization in versions 3.4.44 - 3.32.1.
How to fix this
