CVE-2026-51860
UnknownSummary
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.
Risk Assessment
An attacker can read or manipulate files outside the permitted area, potentially leading to data leakage or compromise of system integrity. The risk is especially relevant in environments with sensitive data.
Recommendation
Upgrade bisheng to a fixed version and verify path validation mechanisms in task_exec.py. Restrict the application process permissions to the minimum necessary.
Other vulnerabilities in bisheng
See all- CVE-2026-51861Unknown
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-2026-51859Unknown
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-2026-82285High
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.
