3DescriptionCVE.org
Agno's PythonTools in libs/agno/agno/tools/python.py contains a path traversal vulnerability that 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. Attackers can inject traversal sequences such as '../../../../../../etc/passwd' through direct tool invocation or via prompt injection embedded in agent-processed content to escape the intended base_dir boundary and achieve arbitrary file read, arbitrary file write, or arbitrary Python code execution within the process user's authority.
AnalysisAI
Arbitrary file read, write, and Python code execution in Agno's PythonTools (agno.tools.python) exposes any file accessible to the agent process via path traversal sequences injected into the file_name argument of read_file, save_to_file, or run_python_file. The root cause is use of Path.joinpath() without resolving or validating the resulting path against the intended base_dir boundary, enabling escape via sequences such as '../../../../../../etc/passwd'. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an agno agent deployment with PythonTools instantiated and reachable by the attacker either via direct API/tool invocation or via content the agent processes (prompt injection vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.5 with AV:A and UI:A indicates network-adjacent delivery requiring active interaction, which understates real-world risk in agentic deployments: prompt injection via externally sourced content (web pages, documents, API responses) that the agent processes constitutes a network-delivered attack requiring only that the agent pipeline be exposed to untrusted input, pushing the practical attack vector closer to AV:N. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker embeds a prompt injection payload in a webpage or document processed by an agno agent - for example, invisible text instructing the agent to call read_file with file_name='../../../../../../etc/shadow' and relay the output. The agent, lacking independent validation of tool arguments, invokes PythonTools.read_file() with the traversal sequence, bypasses the base_dir boundary, and returns the contents of the sensitive file to the attacker-controlled conversation. … |
| Remediation | The upstream fix is available in commit 710d7e7f846f93b7a3eadfd3e77075428c39e803 (https://github.com/agno-agi/agno/commit/710d7e7f846f93b7a3eadfd3e77075428c39e803); operators should upgrade to the first PyPI release of agno that incorporates this commit - exact version not independently confirmed, so verify at the VulnCheck advisory (https://www.vulncheck.com/advisories/agno-pythontools-path-traversal-via-joinpath-file-name-argument) or the agno release history. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Agno deployments with PythonTools; immediately disable the vulnerable functions (read_file, save_to_file, run_python_file) in production agents unless critical to operations, or apply strict input validation rejecting path traversal sequences including '..' and absolute paths. …
