CVE-2026-76832 Agno AGI CVE debrief

Who should care

Defenders responsible for Agno's PythonTools deployments, including operators, platform administrators, vulnerability management teams, and security teams, should assess exposure and apply remediation to prevent potential arbitrary file read, write, or code execution within the process user's authority. They should review system configurations, verify if vulnerable versions are in use, and monitor for suspicious activity.

Why it matters

CVE-2026-76832 is a high-severity path traversal vulnerability in Agno's PythonTools that allows attackers to read, write, or execute arbitrary files. Defenders responsible for Agno's PythonTools deployments should assess exposure and apply remediation to prevent potential arbitrary file read, write, or code execution within the process user's authority.

• Arbitrary file read within the process user's authority
• Arbitrary file write within the process user's authority
• Arbitrary Python code execution within the process user's authority
• Verification of remediation and compensating controls

Technical summary

The vulnerability allows attackers to read, write, or execute arbitrary files by supplying parent-directory traversal sequences in the file_name argument passed to read_file, save_to_file, or run_python_file tool actions in Agno's PythonTools, specifically in the libs/agno/agno/tools/python.py file. This could lead to arbitrary file read, write, or code execution within the process user's authority. Defenders should focus on validating system configurations, reviewing inventory, and applying remediation steps as recommended.

Defensive priority

High priority for defenders to assess exposure and apply remediation

Recommended defensive actions

• Assess exposure by reviewing system configurations and inventory
• Verify if vulnerable versions are in use
• Apply remediation steps as recommended by the vendor
• Monitor for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but the scope of affected versions and remediation steps require verification from official sources. Affected product deployments should be reviewed for exposure, and defenders should verify system configurations and inventory to assess potential impact. Official advisories and CVE records should be consulted for accurate information on affected scope, severity, and vendor guidance.
