Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-2624 is a path traversal and arbitrary file upload vulnerability in the parisneo/lollms-webui application. It resides in the /switch_personal_path endpoint within lollms_core/lollms/server/endpoints/lollms_user.py, where the path parameter receives insufficient sanitization. The flaw permits attackers to reference arbitrary filesystem locations, enabling direct file uploads, disclosure of personal_data contents, and overwriting of configuration files stored under the same-named directory. The issue affects the latest release prior to the fix and carries a CVSS 3.1 score of 9.8.
An unauthenticated remote attacker can invoke the endpoint with a crafted path value to upload malicious files, exfiltrate sensitive user data, or replace critical configuration entries. Successful exploitation can lead to sensitive information disclosure, unauthorized file placement, and remote code execution through configuration tampering.
The vulnerability was addressed in version 9.4. Public references point to a specific commit (aeba79f3ea934331b8ecd625a58bae6e4f7e7d3f) that implements the correction, along with a detailed report on huntr.com.
EPSS for the CVE rose from lower values to a recorded peak of 0.1033 on 2026-03-16 before receding to the current 0.0631, indicating a measurable increase in exploitation interest after disclosure.

Vulnerability Data
A path traversal and arbitrary file upload vulnerability exists in the parisneo/lollms-webui application, specifically within the `@router.get("/switch_personal_path")` endpoint in `./lollms-webui/lollms_core/lollms/server/endpoints/lollms_user.py`. The vulnerability arises due to insufficient sanitization of user-supplied input for the `path` parameter, allowing an attacker to specify arbitrary…

file system paths. This flaw enables direct arbitrary file uploads, leakage of `personal_data`, and overwriting of configurations in `lollms-webui`->`configs` by exploiting the same named directory in `personal_data`. The issue affects the latest version of the application and is fixed in version 9.4. Successful exploitation could lead to sensitive information disclosure, unauthorized file uploads, and potentially remote code execution by overwriting critical configuration files.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes the '\..\filename' sequence before pathname resolution occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.
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.
Secure SDLC practices directly require input validation and path sanitization that block this traversal vector.
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 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing can discover path-traversal flaws but does not itself prevent them in production code.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements can mandate input validation and path canonicalization to block traversal sequences.
Secure architecture principles include directory sandboxing and safe file-access design that mitigate path traversal.
Secure coding standards directly require neutralizing path traversal sequences such as '\..\filename'.
Information access restriction limits which files an application may read or write.
