CVE-2026-103591: External Control of File Name or Path in AsyncFuncAI deepwiki-open
CVE-2026-103591 is a high-severity vulnerability in AsyncFuncAI's deepwiki-open version 0. It allows unauthenticated attackers to perform arbitrary file reads via the GET /codemap/file endpoint by manipulating the repo_url parameter to bypass path containment checks and specify absolute file paths.
AI Analysis
Technical Summary
DeepWiki-Open version 0 contains an unauthenticated arbitrary file read vulnerability in the GET /codemap/file endpoint. Attackers can supply a non-URL value to the repo_url parameter, bypassing path containment checks and enabling reading of any file accessible to the API process by specifying absolute file paths. This flaw allows exposure of sensitive files without authentication.
Potential Impact
An unauthenticated attacker can read arbitrary files on the server running deepwiki-open, potentially exposing sensitive information accessible to the API process. This could lead to information disclosure and further attacks based on the data obtained.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the vulnerable endpoint and monitor for suspicious activity.
