Versions 0.8.2-rc2 through 0.8.2 are vulnerable to a server-side request forgery (SSRF) attack when using agent actions or MCP. Although a previous SSRF vulnerability (https://github.com/danny-avila/LibreChat/security/advisories/GHSA-rgjq-4q58-m3q8) was reported and patched, the fix only introduced hostname validation. It does not verify whether DNS resolution results in a private IP address. As a result, an attacker can still bypass the protection and gain access to internal resources, such as an internal RAG API or cloud instance metadata endpoints. Version 0.8.3-rc1 contains a patch."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"danny-avila","product":"LibreChat","versions":[{"version":">= 0.8.2-rc2, < 0.8.3-rc1","status":"affected"}]}]}],"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:C/C:H/I:N/A:N","baseScore":7.7,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.1,"impactScore":4.0}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-03-30T19:00:49.640233Z","id":"CVE-2026-31945","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-918"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:librechat:librechat:0.8.2:-:*:*:*:*:*:*","matchCriteriaId":"8D828ED6-3F44-4DD1-B29F-62D8977AF33A"},{"vulnerable":true,"criteria":"cpe:2.3:a:librechat:librechat:0.8.2:rc2:*:*:*:*:*:*","matchCriteriaId":"21865C8B-C628-4275-A552-89F64EF22918"},{"vulnerable":true,"criteria":"cpe:2.3:a:librechat:librechat:0.8.2:rc3:*:*:*:*:*:*","matchCriteriaId":"47A1B487-1A7B-4E06-8503-56E7D349FAA2"}]}]}],"references":[{"url":"https://github.com/danny-avila/LibreChat/security/advisories/GHSA-f92m-jpv7-55p2","source":"security-advisories@github.com","tags":["Exploit","Mitigation","Vendor Advisory"]},{"url":"https://github.com/danny-avila/LibreChat/security/advisories/GHSA-f92m-jpv7-55p2","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Mitigation","Vendor Advisory"]}]}}]}
