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...
