Prior to 1.6.0, SparkyFitnessServer/services/chatService.ts and SparkyFitnessServer/services/labelScanService.ts do not validate destinations supplied in custom AI service settings. An authenticated user saves a custom AI service URL and invokes an affected AI flow. The user can save a custom AI service URL and trigger an outbound request. Successful exploitation can send server-side POST requests with a controlled bearer value, probe internal services, and disclose the AI system prompt. This issue is fixed in version 1.6.0.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/CodeWithCJ/SparkyFitness/commit/0b43a37003a3fbedf4e38058130460fd4707fe29","tags":[]},{"url":"https://github.com/CodeWithCJ/SparkyFitness/releases/tag/v1.6.0","tags":[]},{"url":"https://github.com/CodeWithCJ/SparkyFitness/security/advisories/GHSA-rmxj-43xh-mcm3","tags":[]}],"exploitRefs":[{"url":"https://github.com/CodeWithCJ/SparkyFitness/commit/0b43a37003a3fbedf4e38058130460fd4707fe29","tags":[]},{"url":"https://github.com/CodeWithCJ/SparkyFitness/releases/tag/v1.6.0","tags":[]},{"url":"https://github.com/CodeWithCJ/SparkyFitness/security/advisories/GHSA-rmxj-43xh-mcm3","tags":[]}],"hasPoc":true,"ai":null}
