A server-side request forgery (SSRF) vulnerability has been identified in Bytedesk versions through 1.3.9. The issue arises in the SpringAIGiteeRestController component, specifically within the getModels function of the SpringAIGiteeRestService.java file. The vulnerability allows remote exploitation by manipulating the apiUrl parameter, which is passed to RestTemplate.exchange() without proper validation. This flaw could be exploited to probe internal networks, access cloud metadata services, and potentially exfiltrate credentials.
Upgrade to Bytedesk version 1.4.5.4, which addresses this vulnerability. The patched version is available on the Bytedesk GitHub Releases page.
