CVE-2026-82748 Vulnerability Summary

CVE-2026-82748: Incorrect Authorization vulnerability in ash-project ash authorizes an aggregate under one read action while computing it under another, so an aggregate can run with policies that do not match the action it was authorized against. Ash.Actions.Aggregate groups aggregates by their {authorize?, read_action} and authorizes each group under that read action, but when building the data query it selected the action as opts[:action] || read_action || <primary read> (lib/ash/actions/aggregate.ex). When a caller passed an :action option, the aggregate query ran under that action while authorization had been computed for the group's own read_action. If the run action's read policies are more permissive than the authorized one, the aggregate (a count or sum) is computed over records the authorized action's policies would have excluded, disclosing information about data the actor cannot read. The fix runs the aggregate under the same read_action it is authorized against. This issue affects ash: from 3.5.13 before 3.32.2.

Assessing the Risk of CVE-2026-82748

Access Complexity Graph

The exploitability of CVE-2026-82748 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-82748

No exploitability data is available for CVE-2026-82748.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-82748, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis
