Google Chrome before 1.0.154.53 displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.

Security readout for executives and security teams

This is an old Google Chrome certificate display flaw involving proxy error pages. A vulnerable browser could show a previously cached valid certificate while displaying a proxy-generated error page, making a spoofed HTTPS site appear more trustworthy to the user. Exposure is most likely limited to legacy systems running Chrome before 1.0.154.53, especially where web traffic traverses untrusted or attacker-controlled proxies. The bundle does not identify other affected products. Treat this as a legacy hygiene issue unless vulnerable Chrome versions still exist. If found, prioritize removal because browser trust indicators can influence credential theft and user deception risk. Mitigation focus: Upgrade any affected Chrome installation to 1.0.154.53 or later.; Prefer a currently supported browser for all production use.; Review vendor release notes and Chromium guidance for historical fix details..
