Vulnerability details
An improper access control vulnerability exists in the mintplex-labs/anything-llm application, specifically within the import endpoint. This vulnerability allows an anonymous attacker, without an account in the application, to import their own database file, leading to the deletion or spoofing of…

the existing `anythingllm.db` file. By exploiting this vulnerability, attackers can serve malicious data to users or collect information about them. The vulnerability stems from the application's failure to properly restrict access to the data-import functionality, allowing unauthorized database manipulation.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
