{"id":"CVE-2026-119298","state":"PUBLISHED","title":"croc: Overwrite-confirmation bypass via a crafted \"croc-stdin-\" filename on receive","description":"croc is a tool that allows any two computers to simply and securely transfer files and folders. Prior to 11.5.2, the receive-side file-readiness loop in src/croc/croc.go treats any sender-controlled basename beginning with croc-stdin- as a trusted text-transfer artifact even when SendingText is false. This skips askReceiveOverwrite and rename handling for a predictable exact-name collision in the receiver's working directory, allowing a remote sender whose transfer the user accepts to overwrite or truncate a matching regular file through recipientInitializeFile, or to remove and replace a matching destination with an empty file or an in-directory symlink through createEmptyFileAndFinish, without confirmation. The impact is limited to pre-existing names in the croc-stdin- namespace that the sender can predict; other filenames retain the prompt, dotfiles outside that namespace are not reachable, and symlink targets remain confined to the receive directory. This issue is fixed in version 11.5.2.","publishedAt":"2026-10-30T16:12:49.765Z","updatedAt":"2026-10-30T18:35:53.606Z","severity":{"score":4.2,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["schollz croc"],"affected":[{"vendor":"schollz","product":"croc","versions":[{"version":"< 11.5.2","status":"affected"}]}],"references":["https://github.com/schollz/croc/security/advisories/GHSA-x89h-7h96-v88f","https://github.com/schollz/croc/pull/1327","https://github.com/schollz/croc/commit/25fe49b6f14db99f517e902cfef76299ad0a95a3","https://github.com/schollz/croc/releases/tag/v11.5.2"],"weaknesses":["CWE-73"],"ingestedAt":"2026-10-30T18:40:06.088Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/119xxx/CVE-2026-119298.json","commit":"7c60edf882a89f07fcce8b786bfad034e7ddeecb","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-119298","state":"PUBLISHED","datePublished":"2026-10-30T16:12:49.765Z","dateUpdated":"2026-10-30T18:35:53.606Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-29T18:50:28.066Z"},"containers":{"cna":{"title":"croc: Overwrite-confirmation bypass via a crafted \"croc-stdin-\" filename on receive","descriptions":[{"lang":"en","value":"croc is a tool that allows any two computers to simply and securely transfer files and folders.
