CVE-2026-82760 Superlinear base62 decoding exhausts CPU and memory in AshAuthentication API key sign-in

Inefficient Algorithmic Complexity vulnerability in team-alembic AshAuthentication allows an unauthenticated attacker to exhaust CPU and memory via an oversized base62 segment in a submitted API key. AshAuthentication.Base.decode62/1 in lib/ashauthentication/base.ex splits its argument into one...

CVE-2026-82760

AshAuthentication (Elixir library by team-alembic) is vulnerable to CPU and memory exhaustion via superlinear base62 decoding in the API key sign-in flow. The root cause is in AshAuthentication.Base.decode62/1, which recomputes Integer.pow(62, index) at every character position instead of accumul...
