{"identifier":"CVE-2026-102923","cve":{"id":"CVE-2026-102923","description":"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.","published":"2026-10-16T16:16:52.707000+00:00","modified":"2026-10-28T19:17:17.430000+00:00","status":"Deferred","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-918"],"references":[{"url":"https://github.com/CodeWithCJ/SparkyFitness/commit/0b43a37003a3fbedf4e38058130460fd4707fe29","source":"security-advisories@github.com"},{"url":"https://github.com/CodeWithCJ/SparkyFitness/releases/tag/v1.6.0","source":"security-advisories@github.com"},{"url":"https://github.com/CodeWithCJ/SparkyFitness/security/advisories/GHSA-rmxj-43xh-mcm3","source":"security-advisories@github.com"},{"url":"https://github.com/CodeWithCJ/SparkyFitness/security/advisories/GHSA-rmxj-43xh-mcm3","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","baseScore":5.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":2.5}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-28T18:20:24.682661Z","id":"CVE-2026-102923","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T21:20:12.395055+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00265,"percentile":0.18392,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/CodeWithCJ/SparkyFitness/commit/0b43a37003a3fbedf4e38058130460fd4707fe29","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-102923","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-102923","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-102923","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
