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.","cvss_v4":{"vector":"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","score":2.1},"cvss_v3":null,"cwes":["CWE-863"],"references":["https://cna.erlef.org/cves/CVE-2026-81316.html","https://github.com/ash-project/ash_sql/commit/4b95468e5434a3526571414219719c9518be6694","https://github.com/ash-project/ash_sql/security/advisories/GHSA-v7pf-wjxc-7j5m","https://osv.dev/vulnerability/EEF-CVE-2026-81316","https://github.com/ash-project/ash_sql/security/advisories/GHSA-v7pf-wjxc-7j5m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-81316","score":0.00171,"percentile":0.0642,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
