CVE-2026-82752

Improper Validation of Specified Quantity in Input vulnerability in ash-project ash allows an attacker to store a value of arbitrary size in an attribute whose length constraint should bound it. Ash measures string length with Elixir's String.length/1, which counts Unicode graphemes, in the...

CVE-2026-82752: Improper Validation of Specified Quantity in Input

Improper Validation of Specified Quantity in Input vulnerability in ash-project ash allows an attacker to store a value of arbitrary size in an attribute whose length constraint should bound it. Ash measures string length with Elixir's String.length/1, which counts Unicode graphemes, in the...

CVE-2026-82744

Not Failing Securely Failing Open vulnerability in ash-project ash skips an Ash.Reactor change when the guard controlling it raises, so a change meant to run does not. An Ash.Reactor change step can be gated by where validations that decide whether the change runs. Ash.Reactor.ChangeStep...

CVE-2026-82742

Uncontrolled Resource Consumption vulnerability in ash-project ash lets an attacker exhaust node memory by matching a filter that spans multiple to-many relationships in memory. Ash.Filter.Runtime matches a filter against an in-memory record by first expanding the record into combinations of its...

CVE-2026-82748 Ash.Actions.Aggregate authorizes an aggregate under one action but computes it under another

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?,...

CVE-2026-82746 Ash.update_many/4 atomic path skips resource policy authorization, allowing updates to forbidden records

Missing Authorization vulnerability in ash-project ash allows an actor to update records forbidden by resource policies through the atomic path of Ash.updatemany/4. Ash.updatemany/4 runs as a single atomic statement a data-layer updatemany, for example a SQL MERGE whenever an atomic strategy is...

CVE-2026-82743 Ash.Actions.Read.AsyncLimiter busy-spins a scheduler while awaiting slow async reads

Uncontrolled Resource Consumption vulnerability in ash-project ash lets a slow asynchronous read spin a scheduler thread at full CPU while the framework waits for it. Ash.Actions.Read.AsyncLimiter.awaitatleastone/1 lib/ash/actions/read/asynclimiter.ex waited for concurrent async read tasks by...

EUVD-2026-68948

Uncontrolled Resource Consumption vulnerability in ash-project ash lets a slow asynchronous read spin a scheduler thread at full CPU while the framework waits for it. Ash.Actions.Read.AsyncLimiter.awaitatleastone/1 lib/ash/actions/read/asynclimiter.ex waited for concurrent async read tasks by...

CVE-2026-82742 Ash.Filter.Runtime materializes a combinatorial cross-product over to-many relationships, exhausting memory

Uncontrolled Resource Consumption vulnerability in ash-project ash lets an attacker exhaust node memory by matching a filter that spans multiple to-many relationships in memory. Ash.Filter.Runtime matches a filter against an in-memory record by first expanding the record into combinations of its...

CVE-2026-82742

CVE-2026-82742 is an uncontrolled resource consumption vulnerability in the ash Elixir framework (versions 1.29.0-rc0 through before 3.32.2 ). The root cause is in Ash.Filter.Runtime's flatten_relationships/2 function (lib/ash/filter/runtime.ex), which eagerly materializes the full Cartesian prod...

CVE-2026-82741 Ash.Type.Union with :map_with_tag does not force the tag on dump, enabling tag confusion

Improper Validation of Specified Type of Input vulnerability in ash-project ash lets an attacker confuse the stored type tag of an Ash.Type.Union value that uses storage: :mapwithtag, bypassing that member's validation and any tag-based authorization. For a union with storage: :mapwithtag, each...

CVE-2026-82740 Ash.Type ignores outer array constraints on nested {:array, {:array, type}} inputs

Improper Input Validation vulnerability in ash-project ash fails to enforce the outer array constraints on a doubly-nested :array, :array, type attribute, letting invalid input pass validation. Ash.Type.applyconstraints/3 lib/ash/type/type.ex handled the :array, :array, type case by mapping only...
