FKIE_CVE-2026-81316

Vulnerability from fkie_nvd - Published: 2026-08-30 12:17 - Updated: 2026-09-01 21:15
Severity
2.1 (Low) - CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
Summary
Incorrect Authorization vulnerability in ash-project ash_sql allows a caller to receive an aggregate value computed over rows a more restrictive filter should have excluded, disclosing counts, sums, or lists across an authorization or tenancy boundary. AshSql.Aggregate.different_queries?/2 reports two aggregate queries as different only when their filter and their sort both differ. 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. This issue affects ash_sql: from 0.1.0 before 0.7.1.
