The vulnerability in python-a2a (CVE-2025-XXXX) stems from insufficient path sanitization in the `create_workflow` function within python_a2a/agent_flow/server/api.py. An attacker can exploit this flaw by crafting malicious input containing directory traversal sequences (e.g., ../), allowing unauthorized access to files outside the intended directory. This could lead to sensitive data exposure or arbitrary file overwrites. The issue is fixed in version 0.5.6 by implementing proper path validation.
DailyCVE Form:
Platform: Python-a2a
Version: ≤ 0.5.5
Vulnerability: Path Traversal
Severity: Moderate
Date: Jun 17, 2025
Prediction: Patch expected by Jun 24, 2025
What Undercode Say:
Check installed version
pip show python-a2a
Exploit PoC (simulated traversal)
curl -X POST http://target/api/create_workflow -d '{"path":"../../etc/passwd"}'
Mitigation command
pip install --upgrade python-a2a==0.5.6
How Exploit:
- Craft HTTP request with `../` sequences.
- Bypass directory restrictions.
- Read/overwrite system files.
Protection from this CVE:
- Upgrade to v0.5.6.
- Validate user-supplied paths.
- Use chroot/jail.
Impact:
- Unauthorized file access.
- Data leakage.
