Summary

CVE-2025-6209 is a high-severity Path Traversal: '\..\filename' (CWE-29) vulnerability in Llamaindex Llamaindex. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

A path traversal vulnerability exists in run-llama/llama_index versions 0.12.27 through 0.12.40, specifically within the `encode_image` function in `generic_utils.py`. This vulnerability allows an attacker to manipulate the `image_path` input to read arbitrary files on the server, including sensitive system files. The…

issue arises due to improper validation or sanitization of the file path, enabling path traversal sequences to access files outside the intended directory. The vulnerability is fixed in version 0.12.41.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly neutralizes the '\..\filename' sequence before pathname resolution occurs.

AC-3 Access Enforcement partial match

Access enforcement denies requests that resolve outside the intended directory even when the traversal sequence is present.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that block this traversal vector.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can discover path-traversal flaws but does not itself prevent them in production code.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate input validation and path canonicalization to block traversal sequences.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles include directory sandboxing and safe file-access design that mitigate path traversal.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require neutralizing path traversal sequences such as '\..\filename'.
