Network-exposed endpoint requires no authentication; file inclusion yields limited read and potential write impact with no scope change to other systems.

Lifecycle Timeline
3DescriptionCVE.org
A weakness has been identified in TinyAGI 0.0.20. This issue affects the function collectFiles of the file packages/core/src/response.ts of the component Message API Endpoint. This manipulation causes file inclusion. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
File inclusion via unsanitized path input in TinyAGI 0.0.20's Message API Endpoint exposes server-side files to remote unauthenticated attackers. The vulnerable surface is the collectFiles function in packages/core/src/response.ts, which accepts externally controlled file paths without adequate validation (CWE-73). Publicly available exploit code exists via GitHub issue #282, and the project maintainer had not issued a patch or response at time of disclosure - compounding risk for any internet-exposed deployments.
Technical ContextAI
CWE-73 (External Control of File Name or Path) describes a class of vulnerability where user-supplied input is used directly - or with insufficient sanitization - to construct file system paths in a server-side operation. In TinyAGI 0.0.20, the affected function collectFiles resides in packages/core/src/response.ts and is invoked through the Message API Endpoint, an interface designed to handle LLM-oriented message payloads. When file path parameters in that API are attacker-controlled, the runtime reads or includes files from the server filesystem based on attacker-supplied names. The CPE identifier cpe:2.3:a:n/a:tinyagi:*:*:*:*:*:*:*:* reflects that no authoritative vendor CPE is registered, indicating an unvetted or immature project in the supply chain context. The CVSS 4.0 vector AV:N/AC:L/AT:N/PR:N/UI:N confirms default network reachability with no prerequisites.
RemediationAI
No vendor-released patch has been identified at time of analysis - the project maintainer had not responded to the coordinated disclosure filed via GitHub issue #282. Until a fix is released, operators should immediately restrict network access to the TinyAGI Message API Endpoint using firewall rules or reverse-proxy ACLs, ensuring it is not exposed to untrusted networks or the internet. If the endpoint must remain accessible, consider deploying a web application firewall rule to reject requests containing path traversal sequences (e.g., ../, absolute paths, or null bytes) targeting the file parameter - note this is a compensating control, not a fix, and bypass may be possible. Disabling the collectFiles feature entirely at the application layer is the most effective workaround if that functionality is non-essential. Monitor https://github.com/TinyAGI/tinyagi/ for a patched release and upgrade immediately upon availability.
