Affected is the function Bun.serve of the file buildCache.js of the component API. Performing a manipulation of the argument pathname results in path traversal. It is possible to initiate the attack remotely. The exploit is now public and may be used. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The vendor was contacted early about this disclosure but did not respond in any way.","publishedAt":"2026-04-20T12:00:17.473Z","updatedAt":"2026-04-20T14:58:24.131Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","source":"VulDB"},"assigner":"VulDB","products":["p2r3 convert"],"affected":[{"vendor":"p2r3","product":"convert","versions":[{"version":"6998584ace3e11db66dff0b423612a5cf91de75b","status":"affected"}],"modules":["API"]}],"references":["https://vuldb.com/vuln/358270","https://vuldb.com/vuln/358270/cti","https://vuldb.com/submit/793436","https://github.com/Dave-gilmore-aus/security-advisories/blob/main/convert-advisory"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6636.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6636","state":"PUBLISHED","datePublished":"2026-04-20T12:00:17.473Z","dateUpdated":"2026-04-20T14:58:24.131Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-04-19T19:23:02.842Z"},"containers":{"cna":{"title":"p2r3 convert API buildCache.js Bun.serve path traversal","descriptions":[{"lang":"en","value":"A vulnerability was detected in p2r3 convert up to 6998584ace3e11db66dff0b423612a5cf91de75b.
