9DescriptionCVE.org
A vulnerability was found in ageerle ruoyi-ai 2.0.0 and classified as critical. Affected by this issue is the function speechToTextTranscriptionsV2/upload of the file ruoyi-modules/ruoyi-system/src/main/java/org/ruoyi/system/service/impl/SseServiceImpl.java. The manipulation of the argument File leads to unrestricted upload. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.0.1 is able to address this issue. The patch is identified as 4e93ac86d4891c59ecfcd27c051de9b3c5379315. It is recommended to upgrade the affected component.
AnalysisAI
Unrestricted file upload in ruoyi-ai 2.0.0 allows remote authenticated attackers to upload arbitrary files via the speechToTextTranscriptionsV2/upload endpoint. Public exploit code exists, and a patch is available in version 2.0.1. EPSS score is low (0.15%), indicating limited exploitation likelihood.
Technical ContextAI
The vulnerability resides in the SseServiceImpl.java file within the ruoyi-modules/ruoyi-system module. The function speechToTextTranscriptionsV2/upload accepts a MultipartFile argument without validating the file extension, allowing unrestricted upload. The CWE-284 (Improper Access Control) classification indicates missing authorization checks. The patch adds file extension validation using a whitelist of allowed extensions (e.g., audio formats) and generates a secure file path with a UUID to prevent path traversal. The affected product is ruoyi-ai, a Java-based AI application built on the RuoYi framework.
RemediationAI
Upgrade to ruoyi-ai version 2.0.1, which includes the fix commit 4e93ac86d4891c59ecfcd27c051de9b3c5379315. The patch adds file extension validation and secure file path generation. As a workaround, restrict access to the /upload endpoint via network controls or authentication, though the vulnerability already requires authentication. Disabling the speech-to-text feature may also mitigate risk.
