{"identifier":"CVE-2026-40116","cve":{"id":"CVE-2026-40116","description":"PraisonAI is a multi-agent teams system. Prior to 4.5.128, the /media-stream WebSocket endpoint in PraisonAI's call module accepts connections from any client without authentication or Twilio signature validation. Each connection opens an authenticated session to OpenAI's Realtime API using the server's API key. There are no limits on concurrent connections, message rate, or message size, allowing an unauthenticated attacker to exhaust server resources and drain the victim's OpenAI API credits. This vulnerability is fixed in 4.5.128.","published":"2026-04-09T22:16:35.297000+00:00","modified":"2026-10-26T22:10:00.163000+00:00","status":"Analyzed","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_version":"3.1","affected":[{"criteria":"cpe:2.3:a:praison:praisonai:*:*:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"","versionEndExcluding":"4.5.128"}],"weaknesses":["CWE-770"],"references":[{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-q5r4-47m9-5mc7","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-q5r4-47m9-5mc7","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Vendor Advisory"]}],"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:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-14T14:42:36.529534Z","id":"CVE-2026-40116","options":[{"exploitation":"poc"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:praison:praisonai:*:*:*:*:*:*:*:*","versionEndExcluding":"4.5.128","matchCriteriaId":"56CDE5F5-B03C-4C3A-9A92-F61C9DFDA9B1"}]}]}],"source":"nvd","retrieved_at":"2026-10-28T10:18:43.866384+00:00","exploited":false,"kev_stale":false,"products":["praison / praisonai"],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00372,"percentile":0.30986,"date":"2026-10-27","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-q5r4-47m9-5mc7","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-40116","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-40116","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-40116","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
