CyberRota Analysis
AI-GeneratedAdminer versions 4.6.0 through 5.5.0 are vulnerable due to an incomplete fix for an X-Forwarded-Prefix vulnerability, allowing malformed prefixes to potentially influence cookie-path scoping. This could lead to unintended cookie exposure if clients can manipulate the X-Forwarded-Prefix header, typically due to misconfigured reverse proxies. Organizations using affected Adminer versions should prioritize upgrading to 5.5.1 to mitigate this low-severity risk.

Original NVD Description
Adminer 4.6.0 through 5.5.0 (fixed in 5.5.1) contains an incomplete fix for a prior X-Forwarded-Prefix vulnerability (GHSA-8478-xrj3-h9c2). The validation guard (bootstrap.inc.php) only rejects prefixes matching ^/[^/], blocking //evil.com but allowing values such as /\evil.com whose second character is a backslash. Because browsers normalize backslash to forward slash, a network-path reference survives into REQUEST_URI and reaches cookie_path(), affecting the Set-Cookie Path attribute. Exploitation requires that clients can set the X-Forwarded-Prefix header (a misconfigured or absent reverse proxy). Impact is limited to anomalous cookie-path scoping.
