CVE-2026-111363
MediumCVSS 6.5Summary
BISHENG through 3.0.0-beta4 contains an insecure direct object reference vulnerability that allows authenticated low-privileged users to read other users' parsed documents by supplying arbitrary file_id values. Attackers can enumerate sequential file ids against GET /api/v1/knowledge/file_bbox to retrieve extracted page text from other users' and tenants' knowledge bases.
Risk Assessment
Low-privileged users can access confidential documents from other users' and tenants' knowledge bases, leading to information disclosure.
Recommendation
Update BISHENG to a version later than 3.0.0-beta4 if available and enforce file authorization checks based on user and tenant identity.
Other vulnerabilities in BISHENG
See all- CVE-2026-51861Critical
bisheng 2.3.0, 2.4.0, and 2.4.0-beta1 is vulnerable to Code Injection in src/backend/bisheng/api/v1/validate.py. The vulnerability allows unauthorized code execution in the application context.
- CVE-2026-51859Critical
bisheng 2.3.0, 2.4.0, and 2.4.0-beta1 is vulnerable to directory traversal in save_download_file (src/backend/bisheng/core/cache/utils.py:290). The vulnerability allows access to files outside the intended area.
- CVE-2026-51860High
bisheng 2.3.0, 2.4.0, and 2.4.0-beta1 is vulnerable to Directory Traversal in src/backend/bisheng/linsight/domain/task_exec.py. The vulnerability allows access to files outside the intended directory.
- CVE-2026-82285High
bisheng through 2.6.0-fix2 contains a server-side request forgery vulnerability in the POST /api/v1/workflow/report/callback endpoint that lacks authentication and applies no URL scheme restrictions or host filtering. Unauthenticated attackers can supply arbitrary URLs to enumerate internal network services and cloud metadata endpoints, then retrieve captured responses from object storage using caller-supplied object names.
- CVE-2026-82278High
BISHENG before 2.6.0 contains a remote code execution vulnerability in the workflow run_once endpoint that allows authenticated users to execute arbitrary Python code. Attackers can submit crafted Code node definitions to the POST /api/v1/workflow/run_once endpoint, which executes them with exec() without sandboxing, gaining access to filesystem, credentials, and internal network resources.
