CVE-2026-82738 Ash.Type.UUIDv7 accepts non-v7 UUIDs that then fail to load, causing persistent denial of service

Improper Input Validation vulnerability in ash-project ash allows an attacker to persistently deny reads of a record by storing a non-version-7 UUID in an Ash.Type.UUIDv7 attribute. Ash.Type.UUIDv7.castinput/2 accepts any well-formed UUID string, including non-version-7 UUIDs, and stores it as a...

CVE-2026-82737 Ash.Vector wraps the 16-bit dimension header for vectors over 65,535 elements, corrupting data and crashing reads

Integer Overflow or Wraparound vulnerability in ash-project ash lets an attacker corrupt a stored vector and crash later reads of it by submitting a vector with more than 65,535 elements. Ash.Vector.new/1 lib/ash/vector.ex encodes a vector as followed by the element floats, packing the element...

EUVD-2026-68963

Incorrect Behavior Order: Validate Before Canonicalize vulnerability in ash-project ash lets an attacker store a case-insensitive string value that violates its length or match constraints.

CVE-2026-82741: Improper Validation of Specified Type of Input

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-2026-82742: Uncontrolled Resource Consumption

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.
