{"id":"CVE-2026-61840","state":"PUBLISHED","title":"Quest Bot: Server Side Request Forgery in the Image to GIF Feature Lets Any Server Member Reach Internal Services","description":"Quest Bot is an opensource Discord Bot. Prior to 1.1.9, the `image to GIF` command uses a request helper that validates a hostname's public IP addresses but then sends the actual request by hostname, causing a `second DNS lookup`. An attacker controlling a domain can return a public address during validation and an internal address during the connection, bypassing the internal-address protection through `DNS rebinding`. The command takes its address directly from user input and its developer-only gate is disabled in normal deployments, so any member of a server with the bot can trigger the flaw without special permissions. Requests are restricted to `HTTPS on port 443`, and content is returned only when the response is a `genuine image`. The impact is therefore mostly blind internal probing with limited retrieval of image responses from loopback or internal endpoints, not arbitrary internal-data disclosure. Common cloud metadata services using plain HTTP on another port are not reachable through this path. This issue is fixed in version 1.1.9.","publishedAt":"2026-10-30T18:23:22.213Z","updatedAt":"2026-10-30T22:17:17.865Z","severity":{"score":2.3,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["vantern-org questbot"],"affected":[{"vendor":"vantern-org","product":"questbot","versions":[{"version":"< 1.1.9","status":"affected"}]}],"references":["https://github.com/vantern-org/questbot/security/advisories/GHSA-hrp5-g9r6-8rq4","https://github.com/vantern-org/questbot/commit/eec5f57eda8caa37cd46520c57b3c01efef2b99b"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-30T22:26:06.415Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61840.json","commit":"f02cde01d713f161fa6518ef321d5dace5470571","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61840","state":"PUBLISHED","datePublished":"2026-10-30T18:23:22.213Z","dateUpdated":"2026-10-30T22:17:17.865Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T20:28:17.512Z"},"containers":{"cna":{"title":"Quest Bot: Server Side Request Forgery in the Image to GIF Feature Lets Any Server Member Reach Internal Services","descriptions":[{"lang":"en","value":"Quest Bot is an opensource Discord Bot.
