Sanitize shadowCallRewrittenFrom before retaining the entry.
appendUsageEntry sanitizes this field before writing usage.jsonl, but addRequestLog retains the original entry first at src/server/request-log.ts:337. /api/logs then spreads retained entries through requestLogDto, so an exported addRequestLog caller can bypass sanitizeLogMetadataString and expose control characters or secret-shaped text. Sanitize a copy before retention and reuse it for persistence. Add a direct-call regression test in tests/request-log.test.ts.

Thank you @Ingwannu — absorbed as #2166, with both of your commits preserved. The diagnosis is entirely yours and it is a real one: One correction. You sanitize at the single call site in Worth noting how that surfaced, because it is a useful pattern: your persistence test uses a safe short slug, so it passes identically whether the sanitizer runs or not. Adding a fixture with a newline and an 80-character tail turned it red immediately. One scope note: #2157 stays open. This is the backend attribution half, and the dashboard still has no badge or filter for the field ( Full suite 13564 pass / 0 fail. Closing this in favor of #2166, credited to you. |
Builds on @Ingwannu's lidge-jun#2163, which types and persists shadowCallRewrittenFrom so an intercepted helper request keeps its original model in usage.jsonl and across restart hydration. The original sanitized the value at the single call site that populates it today, which left the in-memory /api/logs row carrying whatever the caller sent. The marker originates in an upstream-supplied model id, so an unsanitized newline lets one field forge a record boundary in any line-oriented log viewer, and nothing bounded its length on that path. addFinalRequestLog now runs it through sanitizeLogMetadataString itself. A future caller cannot reintroduce the hole by forgetting to sanitize first, and the in-memory row matches what usage.jsonl already stored. The added regression writes an unsafe overlong marker and asserts the newline is gone and the 64-character bound holds on both paths. The original test used a safe short slug, so it passed identically whether the sanitizer ran or not.
