EPSS

• CVE-2026-25130: 0.91% estimated exploitation activity in the next 30 days; percentile 59.90 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The CAI (Cybersecurity AI) framework contains multiple argument injection vulnerabilities in its function tools. User-controlled input is passed directly to shell commands via `subprocess.Popen()` with `shell=True`, allowing attackers to execute arbitrary commands on the host system.

Vulnerable Component Function: `find_file()` in `src/cai/tools/reconnaissance/filesystem.py` code ```python @function_tool def find_file(file_path: str, args: str = "", ctf=None) -> str: command = f'find {file_path} {args}'

No sanitization return run_command(command, ctf=ctf)

shell=True ```

Attack Vector An attacker can exploit this vulnerability through prompt injection: 1. Attacker hosts a webpage containing malicious instructions in HTML comments 2. Victim's CAI agent fetches and processes the webpage 3. Agent is tricked into calling…

# Patch Next advisory brief: CVE-2026-25130

Advisory: CAI find_file Agent Tool has Command Injection Vulnerability Through Argument Injection
IDs: CVE-2026-25130, GHSA-jfpc-wj3m-qw2m
Record: https://patchnext.com/advisories/cve-2026-25130 (revision 5, source checked 28 Oct 2026, 06:10 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI cai-framework: affected <= 0.5.10

## Suggested inspection (read-only)
- `python -m pip show cai-framework`: prints the installed version. Run with the environment that serves production active.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on cai-framework.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-jfpc-wj3m-qw2m (GitHub-reviewed advisory GHSA-jfpc-wj3m-qw2m lists affected ranges: PyPI cai-framework >=0 <=0.5.10)
- Verified: https://osv.dev/vulnerability/GHSA-jfpc-wj3m-qw2m (OSV record GHSA-jfpc-wj3m-qw2m lists affected ranges: PyPI cai-framework >=0 <=0.5.10)
