DeepWiki-Open through commit d92819a contains an arbitrary file read vulnerability in the unauthenticated /ws/chat WebSocket endpoint that accepts repo_url as a filesystem path with no containment. Attackers can supply arbitrary directory paths to read all files with supported extensions including Python, JavaScript, YAML, and JSON files containing hardcoded secrets and credentials.
AnalysisAI
Unauthenticated arbitrary file read in DeepWiki-Open (AsyncFuncAI) through commit d92819a lets anyone who can reach the /ws/chat WebSocket endpoint pass an arbitrary directory path as the repo_url parameter and have the server walk that path with no containment check, exfiltrating every readable Python, JavaScript, YAML and JSON file it finds. Because the read is aimed at source and configuration files, the practical payoff is hardcoded secrets, API keys and credentials rather than code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the DeepWiki-Open /ws/chat WebSocket endpoint to be network-reachable by the attacker and to have no authentication layer in front of it - the CVSS 4.0 vector is PR:N/UI:N, so no credentials and no user interaction are needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector is AV:N/AC:L/AT:N/PR:N/UI:N with VC:H and no integrity or availability impact, and that maps to a CVSS 3.1 equivalent of roughly 7.5 - high severity, but a confidentiality-only primitive, not the remote code execution implied by the 'RCE' tag in the source metadata. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version is identified in the available data, so the primary action is to track https://github.com/AsyncFuncAI/deepwiki-open/issues/536 and the project repository for a fix commit or tagged release, and to upgrade as soon as one is published; until then, treat the deployment as untrusted-input-facing. … Detailed patch versions, workarounds, and compensating controls in full report. |
