Fix not verifiedAn authenticated user with limited read privileges may be able to access documents from collections they are not authorized to read, due to an inconsistency in how the $graphLookup aggregation stage is evaluated during authorization and during execution. Affected scenarios involve collections referenced within existing view pipeline definitions.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
