How to fix?

Upgrade Minimos:latest openclaw to version 2026.4.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openclaw package and not the openclaw package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Impact: The morgan logging middleware's :remote-user token extracts the Basic auth username from the Authorization request header and writes it to the log stream without neutralizing control characters. An unauthenticated attacker can send a crafted Authorization Basic header containing CR or LF bytes to inject forged log lines, breaking the one-request-per-line structure of access logs and enabling log forgery against downstream log consumers. The built-in combined, common, default, and short formats are affected, as well as any custom format that references :remote-user. Affected versions: morgan 1.2.0 through 1.10.1. Patches: upgrade to morgan 1.11.0, which neutralizes control characters in the :remote-user token output. Workarounds: use a custom format string that does not include :remote-user.
