CVE-2024-58404 in Zipline
Summary
by MITRE • 11/13/2026
Zipline versions from 3.4.5 before 3.7.10 contain a path traversal vulnerability in the user data export endpoint via the name query parameter. Authenticated attackers can bypass the user id check and use directory traversal sequences to read arbitrary files on the server host.

The Zipline trading platform, specifically versions ranging from 3.4.5 up to but not including 3.7.10, contains a critical path traversal vulnerability within its user data export functionality. This security flaw resides in the endpoint responsible for handling file exports requested by authenticated users. The core issue stems from insufficient validation of input parameters provided via the name query parameter. While the application is designed to restrict access so that users can only retrieve their own exported data, the implementation fails to properly sanitize or canonicalize the filename supplied by the client before processing it on the server side. This oversight allows an attacker to manipulate the file path structure using standard directory traversal sequences, such as dot-dot-slash characters, effectively breaking out of the intended user-specific directory boundaries.
From a technical perspective, this vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory. The flaw represents a classic example of insecure direct object references combined with path traversal logic errors. When an authenticated attacker submits a crafted request containing these traversal sequences in the name parameter, the server-side code interprets them as valid directory navigation commands rather than rejecting them as malicious input. Consequently, instead of returning only the requested user data file located within the secure export folder, the application resolves the path to arbitrary locations on the underlying operating system's filesystem. This behavior bypasses the intended access control mechanisms that are supposed to verify if the requesting user ID matches the owner of the target file, as the traversal allows the attacker to reference files outside the scope of their authorized data set entirely.
The operational impact of this vulnerability is severe, particularly in environments where Zipline hosts sensitive financial or personal information alongside other critical system configurations. An authenticated adversary can exploit this flaw to read arbitrary files from the server host. This could lead to the exposure of configuration files containing database credentials, API keys, private certificates, or internal network topology details. In a worst-case scenario, if the application runs with elevated privileges or if sensitive data is stored in accessible locations like /etc/passwd or environment variable files, the attacker gains significant insight into the infrastructure's security posture. This information can subsequently be leveraged for further attacks, such as credential stuffing, lateral movement within the network, or privilege escalation, thereby compromising the confidentiality and integrity of the entire system ecosystem.
To mitigate this risk, organizations running affected versions must upgrade Zipline to version 3.7.10 or later immediately, as this release includes patches that enforce strict input validation on file paths. Until an upgrade is feasible, administrators should implement compensating controls such as web application firewall rules that detect and block requests containing directory traversal patterns in query parameters. Additionally, ensuring the application runs with minimal filesystem permissions can limit the extent of data exposure if exploitation occurs. It is also advisable to review access logs for any signs of attempted path traversal attacks against the export endpoint during the window when vulnerable versions were in production. This vulnerability aligns with MITRE ATT&CK technique T1083, which covers File and Directory Discovery, highlighting how attackers use such flaws to map out target systems before executing more destructive actions.
