agnainpmDescription
Summary
A vulnerability has been discovered in Agnai that permits attackers to upload image files at attacker-chosen location on the server. This issue can lead to image file uploads to unauthorized or unintended directories, including overwriting of existing images which may be used for defacement.
This does not affect:
- agnai.chat
- installations using S3-compatible storage
- self-hosting that is not publicly exposed
CWE-35: Path Traversal

Details
This is a path traversal vulnerability. An attacker can exploit this vulnerability by sending a specially crafted request to the editCharacter handler https://github.com/agnaistic/agnai/blob/75abbd5b0f5e48ddecc805365cf1574d05ee1ce5/srv/api/character.ts#L140:
POST /api/character/28cbe508-2fa9-4890-886e-61d73e22006c%2f%2e%2e%2f%2e%2e%2f%2e%2e%2f%2e%2e%2f%2e%2e%2f%61%70%70%2f%64%69%73%74%2f%64%61%6e%79%61%6e%67 HTTP/1.1
The path traversal character sequence makes it’s way into the id variable which is then string interpolated into filename.
export async function entityUpload(kind: string, id: string, attachment?: Attachment) {
if (!attachment) return
const filename = `${kind}-${id}`
return upload(attachment, filename)
}
No path normalization is conducted nor checked, so attackers can freely manipulate the path which the file is uploaded to.
Impact
This vulnerability is classified as a path traversal vulnerability. Attackers can upload image files to arbitrary locations, potentially overwriting critical system image files.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for agnai, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update agnai to 1.0.330 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-47171 is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
