CVE-2026-91986 Details
Description
gitoxide gix-transport before 0.59.2 fails to filter control characters in git-daemon connect requests, allowing attackers to inject NUL/CR/LF bytes via crafted git URLs. Attackers can inject extra NUL-delimited protocol fields to spoof virtual hosts or inject newlines into daemon requests and logs.
A vulnerability exists in Gitoxide Gix-Transport versions prior to 0.59.2, where control characters are not properly filtered in git-daemon connect requests. This flaw allows attackers to inject NUL, CR, or LF bytes through manipulated git URLs. The injection can be used to spoof virtual hosts by adding NUL-delimited protocol fields or to insert newlines into daemon requests and logs.
Users are advised to update to Gitoxide Gix-Transport version 0.59.2 or later, where this vulnerability has been patched.
