Claude Code: Potential session leakage bug in Enterprise ZDR workspace
Original: Potential session/cache leakage between workspace instances or consumer accounts
Why This Matters
Session leakage in an Enterprise ZDR product would represent a serious data isolation and compliance failure for enterprise customers.
A bug report filed July 4, 2026 on the anthropics/claude-code GitHub repo (Issue #74066) describes a potential session or cache leakage between workspace instances in Claude Code. An Enterprise ZDR user reported their agent suddenly referenced an unrelated Minecraft conversation, raising concerns about data isolation.
A GitHub issue (#74066) filed against the anthropics/claude-code repository on July 4, 2026 reports a potential session or cache leakage bug affecting Claude Code. The reporter, authenticated to an Enterprise Zero Data Retention (ZDR) workspace, observed their AI agent unexpectedly pivot to asking about Minecraft temple bricks and referencing Minecraft construction in its recap — content entirely unrelated to their actual session. The reporter speculates the bleed-over could stem from a colleague's session within the same enterprise workspace, or more seriously, from a consumer-plan account — raising significant concerns about whether Enterprise ZDR chat sessions might be exposed to or commingled with non-enterprise traffic. The issue has been labeled with tags: 'area:core,' 'area:security,' 'bug,' and 'platform:macos.' No official Anthropic response or root cause confirmation is included in the available report. The issue remains open at time of publication.
