Aggregate queries rarely carry a sort, so two aggregates that share a name but carry entirely different filters compare as identical. The colliding aggregate keeps its name and is treated as already computed, and select_aggregates returns the first-registered variant's value. The same name reaches the builder twice with different filters when actor or tenant context is stamped into each aggregate's query, so a narrowly filtered aggregate can be served the value of a previously registered broad one.\n\nThis issue affects ash_sql: from 0.1.0 before 0.7.1.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
