CVE-2026-91986: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') in GitoxideLabs gitoxide
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.
AI Analysis
Technical Summary
The vulnerability in gitoxide gix-transport prior to version 0.59.2 arises from improper neutralization of special elements in output used by downstream components. Specifically, it fails to filter control characters in git-daemon connect requests, enabling attackers to inject NUL, CR, and LF bytes through crafted git URLs. This injection can lead to spoofing of virtual hosts or manipulation of daemon requests and logs by injecting extra NUL-delimited protocol fields or newlines.
Potential Impact
Attackers can manipulate git-daemon connect requests by injecting control characters, which may allow spoofing of virtual hosts or tampering with daemon request logs. This could potentially mislead downstream components or logging systems that rely on these inputs, though no direct code execution or privilege escalation is indicated.
Mitigation Recommendations
Users should upgrade gitoxide gix-transport to version 0.59.2 or later, where this vulnerability is fixed. Patch status is confirmed by the version boundary provided. No additional mitigation steps are indicated.
