CVE-2026-101028

A flaw was found in the Ash framework. An authorized user can infer sensitive information from restricted related records by submitting queries that use aggregate functions, such as counting or checking for record existence. Because read authorization policies on related resources are not enforce...

CVE-2026-101028

Incorrect Authorization vulnerability in ash-project ash allows an actor to infer data in related records they cannot read via Ash.count/2, Ash.exists/2 and Ash.aggregate/3. Ash.Actions.Aggregate.run/4 lib/ash/actions/aggregate.ex applied only the root resource's read policy before running the...

CVE-2026-101028 Ash.count, Ash.exists and Ash.aggregate skip related resources' read policies in filters and sorts

CVE-2026-101028

The ash-project ash framework (versions 2.6.0 to 3.34.6 ) contains an Incorrect Authorization vulnerability in the Ash.Actions.Aggregate.run/4 function. The root cause is that the aggregate path skips applying read policies for related resources, whereas the standard read path correctly applies t...

CVE-2026-94201

A flaw was found in ash. When filtering data using atom-typed attributes configured to permit string conversion, input values are converted into permanent internal symbols atoms that cannot be garbage-collected. A remote attacker can exploit this vulnerability by submitting queries with numerous...

CVE-2026-94201

Ash stores :atom-typed attributes as strings and compares them as strings. When such an attribute is referenced in a filter, the comparison value is coerced through Ash.Type.Atom. Because the type defined no coerce/2 callback, coercion fell back to the default castinput/2, which calls...

CVE-2026-94201 Filtering an :atom attribute with unsafe_to_atom? can exhaust the BEAM atom table in Ash

CVE-2026-94201

The ash: library (versions 3.5.1 before 3.34.3) is vulnerable to a denial of service (DoS) attack due to how it handles :atom-typed attributes. When an attribute is configured with unsafe_to_atom?: true, filtering that attribute with attacker-controlled strings causes the system to intern new, pe...

CVE-2026-93477

A flaw was found in Ash. During bulk update and bulk destroy operations, the framework fails to restrict private action arguments that should only be configured by trusted server-side code. An attacker who can supply parameters to these bulk actions can set arbitrary private arguments. This...

CVE-2026-93477

Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in ash-project ash allows a user to set the value of a private action argument on the bulk destroy and bulk update paths. Action arguments declared with public?: false are meant to be set only by trusted...
