{"id":"CVE-2026-102923","summary":"SparkyFitness: SSRF via unvalidated custom_url in AI service settings","details":"SparkyFitness is a self-hosted, AI-powered health and fitness tracker for families. 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.","aliases":["GHSA-rmxj-43xh-mcm3"],"modified":"2026-10-17T02:47:53.241138001Z","published":"2026-10-16T15:53:05.454Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102923.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102923.json"},{"type":"FIX","url":"https://github.com/CodeWithCJ/SparkyFitness/commit/0b43a37003a3fbedf4e38058130460fd4707fe29"},{"type":"WEB","url":"https://github.com/CodeWithCJ/SparkyFitness/releases/tag/v1.6.0"},{"type":"ADVISORY","url":"https://github.com/CodeWithCJ/SparkyFitness/security/advisories/GHSA-rmxj-43xh-mcm3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102923"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/codewithcj/sparkyfitness","events":[{"introduced":"0"},{"fixed":"aae63f759ff7c7d36c324c5cdf551da371c85ab7"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.6.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.17.3","v0.17.2","v0.17.1","v0.17.0","v0.16.9","v0.16.8","v0.16.7","v0.16.6.3","v0.16.6.2","v0.16.6.1","v0.16.6.0","v0.16.5.9","v0.16.5.8","v0.16.5.7","v0.16.5.6","v0.16.5.5","v0.16.5.4","v0.16.5.3","v0.16.5.2","v0.16.5.1","v0.16.5.0","v0.16.4.9","v0.16.4.8","v0.16.4.6","v0.16.4.5","v0.16.4.4","v0.16.4.3","v0.16.4.2","v0.16.4.1","v0.16.4.0","v0.16.3.6","v0.16.3.5","v0.16.3.4","v0.16.3.3","v0.16.3.2","v0.16.3.1","v0.16.3","v0.16.2","v0.16.1","v0.16.0","v0.15.9.9","v0.15.9.8","v0.15.9.7","v0.15.9.6","v0.15.9.5","v0.15.9.4","v0.15.9.3","v0.15.9.2","v0.15.9.1","v0.15.9","v0.15.8.5","v0.15.8.4","v0.15.8.3","v0.15.8.2","v0.15.8.1","v0.15.7.3","v0.15.7.2","v0.15.7.1","v0.15.7","v0.15.6","v0.15.5.4","v0.15.5.3","v0.15.5.2","v0.15.5.1","v0.15.5","v0.15.4.1","v0.15.4","v0.15.3.1","v0.15.3","v0.15.2.1","v0.15.2","v0.15.1","v0.15.0","v0.14.9","v0.14.8","v0.14.7","v0.14.6","v0.14.5","v0.14.4","v0.14.3","v0.14.2","v0.14.1","v0.14","v0.13","v0.12.1","v0.12","v0.11","v0.10.1","v0.10","v0.09","v0.07.1","v0.07","v0.06","v0.05","v0.04","v0.03","v0.02","v0.01"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-102923.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"}]}
