CVE-2026-82579
MediumCVSS 6.0Summary
In ash_ai (from 0.6.0 before 1.0.0), a vulnerability allows an infinite loop. An attacker who can influence model outputs can hang the tool loop and cause unbounded, repeated model requests.
Risk Assessment
Infinite loop may lead to system overload and resource exhaustion, potentially resulting in denial of service (DoS).
Recommendation
Upgrade ash_ai to version 1.0.0 or later, which includes the fix.
Other vulnerabilities in ash_ai
See all- CVE-2026-82580Medium
In ash_ai (from 0.6.0 before 1.0.0), a vulnerability allows disclosure of sensitive information in error messages. Exceptions during tool execution are sent to chat users without filtering, potentially revealing internal technical details.
- CVE-2026-82564High
An authorization bypass through user-controlled key vulnerability in ash_ai allows a caller to update or destroy records it never identified, including every row in the table. The identity filter is built directly from raw tool arguments.
- CVE-2026-75760High
A vulnerability in ash_ai discloses provider request state and credentials in a user-facing validation error. When the embedding provider call fails, the error contains the raw error term, which may include the URL, response body, and Authorization header with the API key.
- CVE-2026-81315High
An Origin Validation Error vulnerability in ash-project ash_ai allows a malicious web page to bypass the MCP server's DNS-rebinding protection and issue cross-site requests to a user's local MCP server with that user's actor. With default allowed_origins: nil, origin_allowed?/3 accepts an origin when uri.host == conn.host and the forwarded scheme is https, both attacker-controlled. The issue affects ash_ai from 0.8.0 before 1.0.0.
- CVE-2026-77956Critical
A code injection vulnerability in ash-project ash_ai allows a remote, unauthenticated client to execute arbitrary Elixir code. AshAi.Actions.Prompt evaluates prompt content through EEx.eval_string/2, and when prompt content incorporates request data, attacker-controlled text is compiled and run as an EEx template. This affects ash_ai from 0.1.0 before 1.0.0.
Original NVD description (English source)
Loop with Unreachable Exit Condition (Infinite Loop) vulnerability in ash-project ash_ai allows an attacker who can influence a model's output to hang the tool loop and drive unbounded, repeated model requests. AshAi.ToolLoop classifies a model response of :tool_calls, then filters the calls through normalize_tool_calls/2 and unprocessed_tool_calls/2. Both can empty the list: a call missing a valid name, or one reusing a tool_call_id that already has a result in history, is dropped. With an empty list the loop appended nothing and recursed with a byte-identical message list, so the conversation never advanced and the same request was re-sent every iteration. Under the supported max_iterations: :infinity this never terminated; otherwise it exhausted the full budget. Prompt-injected content can make the model re-emit a spent tool_call_id. The fix treats an empty post-filter list as terminal. This issue affects ash_ai: from 0.6.0 before 1.0.0.
