{"id":"CVE-2026-65702","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-65702","summary":"Vanna 2.0.2 Path Traversal via FileSystemConversationStore","details":"Vanna through 2.0.2 contains a path traversal vulnerability in the FileSystemConversationStore persistence integration that allows unauthenticated remote attackers to write attacker-controlled JSON files to arbitrary filesystem locations and read conversation metadata from outside the intended store base directory. Attackers can supply path traversal sequences in the conversation_id parameter submitted to the unauthenticated chat API endpoints to escape the base directory during both write and read operations, enabling arbitrary file write with attacker-controlled content and unauthorized file read on the server filesystem.","published":"2026-07-23T17:09:37.574Z","modified":"2026-08-12T03:51:44.653929349Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/65xxx/CVE-2026-65702.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65702"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vanna-path-traversal-via-filesystemconversationstore"},{"type":"PACKAGE","url":"https://github.com/vanna-ai/vanna"},{"type":"EVIDENCE","url":"https://github.com/geo-chen/oss/blob/main/vanna.md"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:44.653929349Z"}}
