Summary

CVE-2026-29871 is a high-severity Path Traversal (CWE-22) vulnerability in Theunwindai Awesome Llm Apps. 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 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as LLM Application Platforms; in the Privacy and Disclosure risk domain.

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

CVE-2026-29871 is a path traversal vulnerability (CWE-22) affecting the awesome-llm-apps project at commit e46690f99c3f08be80a9877fab52acacf7ab8251, dated 2026-01-19. It resides in the Beifong AI News and Podcast Agent backend, built with FastAPI, specifically in the stream-audio endpoint defined in the file routers/podcast_router.py within the stream_audio function. The vulnerability arises because the endpoint accepts a user-controlled path parameter that is concatenated directly into a filesystem path without proper validation or restriction, enabling unauthorized file access.

An unauthenticated remote attacker can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L), no privileges (PR:N), no user interaction (UI:N), and unchanged scope (S:U). By supplying a crafted path parameter, such as one using directory traversal sequences, the attacker can read arbitrary files from the server filesystem. This may disclose sensitive information, including configuration files and credentials, with a CVSS v3.1 base score of 7.5 (C:H/I:N/A:N) indicating high confidentiality impact.

Mitigation details and additional information are available in the security research advisory at https://github.com/lilmingwa13/security-research/blob/main/CVE-2026-29871.md, published on 2026-03-27.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
