morgan vulnerable to Log Forging via unneutralized control characters in :remote-user

CVE-2026-5078 / GHSA-4vj7-5mj6-jm8m

More information

Details

Impact

Morgan's :remote-user token extracts the Basic auth username from the Authorization header and writes it to the log stream without neutralizing control characters. An attacker can send a crafted Authorization: Basic header containing CR/LF characters to inject forged log lines, corrupting the one-request-per-line structure of access logs.

The built-in combined, common, default, and short formats are affected, as well as any custom format that includes :remote-user.

Patches

Users should upgrade to version 1.11.0.

Workarounds

Use a custom format string that does not include :remote-user.

  • CVSS Score: 5.3 / 10 (Medium)
