CVE-2026-2111 in JeecgBoot
Summary
by MITRE • 02/07/2026
A weakness has been identified in JeecgBoot up to 3.9.0. Affected by this issue is some unknown functionality of the file /airag/knowledge/doc/edit of the component Retrieval-Augmented Generation Module. Executing a manipulation of the argument filePath can lead to path traversal. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Analysis

This vulnerability resides within the JeecgBoot framework version 3.9.0 and earlier, specifically targeting the Retrieval-Augmented Generation Module component. The flaw exists in the file path handling mechanism at /airag/knowledge/doc/edit, where insufficient input validation allows malicious actors to manipulate the filePath argument. This represents a classic path traversal vulnerability that enables attackers to access files outside the intended directory structure, potentially leading to unauthorized data access or system compromise.
The technical implementation of this vulnerability stems from inadequate sanitization of user-supplied input parameters within the document editing functionality. When the filePath argument is processed without proper validation or canonicalization, an attacker can inject malicious path sequences such as ../ or ..\ to navigate outside the intended file access boundaries. This weakness aligns with CWE-22 Path Traversal vulnerability classification, which falls under the broader category of improper input validation issues in software systems. The attack vector is particularly dangerous as it operates remotely, requiring no local system access or authentication credentials to exploit.
The operational impact of this vulnerability extends beyond simple unauthorized file access, as it can potentially enable attackers to read sensitive configuration files, database credentials, application source code, or other confidential data stored on the server. The public availability of exploit code significantly increases the risk profile, as it lowers the barrier to exploitation for malicious actors who may not possess advanced technical skills. This vulnerability affects organizations using JeecgBoot versions up to 3.9.0, particularly those implementing Retrieval-Augmented Generation capabilities for knowledge management or document handling functions.
Security mitigation strategies should focus on immediate implementation of input validation controls and canonicalization of file paths before processing user-supplied arguments. Organizations should apply the latest security patches from JeecgBoot maintainers or implement application-level restrictions that prevent traversal sequences from being processed. Network segmentation and access controls should be enforced to limit exposure of vulnerable components, while monitoring systems should be configured to detect suspicious path traversal attempts. The ATT&CK framework categorizes this as a privilege escalation technique through path traversal, emphasizing the need for robust input validation and secure coding practices to prevent such attacks from succeeding. Given the vendor's lack of response to early disclosure, organizations should consider alternative security measures including temporary workarounds or migration to supported versions while awaiting official patches.
