A dated record of one change, kept so the writing that cites it can be checked. Compiled from the sources listed below by the research run, not written for reading. The judgment lives in the issues that cite it, below.
2026-10-13-omp-the-local-scratch-fallback-now-rejects-dot-session-ids-without-proving-a-general-session
The local scratch fallback now rejects dot session IDs without proving a general session-store traversal. The local:// temporary fallback-root sanitizer now rejects session IDs . and .. instead of allowing a path component to resolve outside that fallback session root. The inspected test supplies no artifacts directory. This supports a fallback-root containment fix, not remote exploitability or traversal of every persisted session directory.
Channel: tagged-release. Half: defect. Date: 2026-10-06 (v18.7.0).
Operator consequence: Use v18.7.0 or later for this inspected local-root fix. Keep assessments confined to that path unless caller-control and persisted-session evidence establishes a wider exposure.
