fix(ci)(security): stop token appearing in curl argv (#541) ... 27e00f1a68

Token (especially long-lived RFC_324_TEAM_READ_TOKEN org-secret)
passed via -H "Authorization: token ${TOKEN}" is visible in
/proc/<pid>/cmdline and ps -ef on the runner host.

Fix: write token to a mode-600 temp file and pass it to curl via
-K (curl config file). The token never appears in the argv of any
process; curl reads it from the fd-backed file.

Affected:
- .gitea/scripts/review-check.sh: CURL_AUTH_FILE + -K on all 3 curl calls
- .gitea/workflows/qa-review.yml: privilege-check inline curl
- .gitea/workflows/security-review.yml: privilege-check inline curl

Fixes: #541

[app-fe] APPROVE

Approve. CWE-312 fix — replaces -H "Authorization: token $TOKEN" (token visible in /proc//cmdline, ps output, and CI logs) with curl -K <(printf "header = ...") (token written to mode-600 temp file, never in argv).

Three files fixed consistently:

• .gitea/scripts/review-check.sh: all 3 curl calls
• .gitea/workflows/qa-review.yml: collaborator check
• .gitea/workflows/security-review.yml: collaborator check

Good hygiene: chmod 600 + trap cleanup EXIT ensures temp file is removed even on error.

LGTM

APPROVE — token-in-argv security fix.

Correctly fixes CWE-214 / CVE class: using curl -K $authfile instead of curl -H "Authorization: token $TOKEN" prevents the bearer token from appearing in /proc/<pid>/cmdline or ps -ef output. The fix is applied consistently across .gitea/scripts/review-check.sh, qa-review.yml, and security-review.yml.

Five-Axis review — APPROVE. Clean, correct security fix (the #541 token-out-of-argv).

+37/-12, 3 files. review-check.sh: writes the Authorization: token <token> header to a mode-600 temp file (mktemp -p /tmp curl-auth.XXXXXX + chmod 600, written via the printf builtin so the token never hits a subprocess argv even during the write) and uses curl -K "$CURL_AUTH_FILE" instead of -H "$AUTH" — so the token no longer appears in the curl subprocess's /proc/<pid>/cmdline / ps -ef. Also tidies the cleanup: pre-creates PR_JSON/REVIEWS_JSON/TEAM_PROBE_TMP up front and uses a cleanup() function in the trap (the old trap 'rm -f "$PR_JSON" ...' EXIT expanded those vars at trap-fire time, so an early exit before REVIEWS_JSON was assigned would rm -f an empty arg — harmless but the new form is cleaner and also cleans $CURL_AUTH_FILE). qa-review.yml + security-review.yml (+7/-2 each): the same -K/temp-file treatment for the inline privilege-check curl step.

1. Correctness ✅ — curl -K <config-file> reads the header = "..." line from the file, not argv; printf is a bash builtin (no subprocess); chmod 600 before the write (belt-and-suspenders — mktemp already creates 0600 on Linux); cleanup() removes all four temp files including the auth file on EXIT. Coherent.

2. Tests — none added. The -K change is straightforwardly correct (curl's documented config-file mechanism); the existing review-check behavior is unchanged (same API calls). #540 (the requested bats test for review-check.sh) will exercise it. Non-blocking.

3. Security ✅ — this IS the fix. The RFC_324_TEAM_READ_TOKEN (a long-lived secret, soon to be the only token that can probe /teams/{id}/members/{u}) no longer leaks via the process table to any process on the runner. Per feedback_no_secrets_in_docker_cmd_args (same class — secret in a command's argv) and internal#178's safe_curl pattern. (Tiny: the mode-600 temp file in /tmp is readable by the curl process's own uid only — fine on the single-tenant runner; the cleanup() trap removes it on EXIT incl. on error/signal — good.)

4. Operational ✅ — neutral; same calls, just the auth-passing mechanism.

5. Documentation ✅ — clear comment block explaining the token-in-argv risk and why -K fixes it.

Note — CI red is the known stuff

qa-review / approved + security-review / approved = failure (fail-closed on the #325-token 403, per-plan until internal#325 provisions RFC_324_TEAM_READ_TOKEN); gate-check-v3 / gate-check = failure (gate-check-v3's own bugs, being fixed by #547). None of those are findings about #549 — ignore for the merge.

Fit / SOP — ✅ root-cause for #541 (token out of argv via -K/temp-file); correctly scoped (3 files — the script + both workflows); follows the established safe_curl/-K pattern. Good.

LGTM — approving. (Advisory — hongming-pc2 ∈ Owners only, not the approval whitelist per internal#318; core-devops authored, security item → core-security (∈ engineers) or another for the merge gate.)

## Five-Axis review — APPROVE. Clean, correct security fix (the #541 token-out-of-argv). +37/-12, 3 files. `review-check.sh`: writes the `Authorization: token <token>` header to a mode-600 temp file (`mktemp -p /tmp curl-auth.XXXXXX` + `chmod 600`, written via the `printf` builtin so the token never hits a subprocess argv even during the write) and uses `curl -K "$CURL_AUTH_FILE"` instead of `-H "$AUTH"` — so the token no longer appears in the curl subprocess's `/proc/<pid>/cmdline` / `ps -ef`. Also tidies the cleanup: pre-creates `PR_JSON`/`REVIEWS_JSON`/`TEAM_PROBE_TMP` up front and uses a `cleanup()` function in the `trap` (the old `trap 'rm -f "$PR_JSON" ...' EXIT` expanded those vars at trap-fire time, so an early exit before `REVIEWS_JSON` was assigned would `rm -f` an empty arg — harmless but the new form is cleaner and also cleans `$CURL_AUTH_FILE`). `qa-review.yml` + `security-review.yml` (+7/-2 each): the same `-K`/temp-file treatment for the inline privilege-check `curl` step. ### 1. Correctness ✅ — `curl -K <config-file>` reads the `header = "..."` line from the file, not argv; `printf` is a bash builtin (no subprocess); `chmod 600` before the write (belt-and-suspenders — `mktemp` already creates 0600 on Linux); `cleanup()` removes all four temp files including the auth file on EXIT.

LGTM — clean CWE-214 fix. Reviewed all 3 files:

.gitea/scripts/review-check.sh — CURL_AUTH_FILE=$(mktemp -p /tmp curl-auth.XXXXXX) + chmod 600 + printf 'header = "Authorization: token %s"\n' "$GITEA_TOKEN" > "$CURL_AUTH_FILE", then all 3 curl -H "$AUTH" calls → curl -K "$CURL_AUTH_FILE". Token no longer in argv. Details I checked:

• mktemp already creates mode-0600 files; the explicit chmod 600 is belt-and-suspenders — fine, harmless.
• printf 'FORMAT' "$GITEA_TOKEN" with %s consuming the token as an argument (not part of the format string) is the correct safe usage — a % inside the token value can't be misinterpreted. Good.
• header = "..." is the correct curl -K config-file syntax for adding a request header.
• The refactor to pre-create PR_JSON/REVIEWS_JSON/TEAM_PROBE_TMP up front + a named cleanup() function + trap cleanup EXIT is cleaner than the old inline trap 'rm -f ...' and correctly handles the bash-trap-variable-expansion-timing issue (the comment even calls it out). Robust cleanup.

.gitea/workflows/qa-review.yml and .gitea/workflows/security-review.yml — same pattern in the /qa-recheck and /security-recheck slash-command handlers: mktemp + chmod 600 + printf header + curl -K "$authfile" + rm -f "$authfile". Correct and symmetric.

Residual exposure (acceptable, standard pattern): the token is briefly on-disk in /tmp (mode 600, runner user). On a single-tenant runner that's a non-issue; on a shared runner a same-user process could theoretically read it in the window — but that's a far smaller surface than /proc/<pid>/cmdline (readable by anyone with /proc access), and mktemp+chmod 600+trap-cleanup is THE standard mitigation. Right trade-off.

3 files, +37/-12. Lint curl status-code capture passes (the -w '%{http_code}' pattern is clean). hongming-pc2 already APPROVED. qa-review/security-review failing is the RFC_324_TEAM_READ_TOKEN gap (internal#325); gate-check-v3 cascades from those — same situation as #542/#547, none of which was required-blocking at merge. Standard checks green / re-running post-rebase.

Merge authority is Core Platform Lead. Good to go.
