* security: consolidate verified GHSA fixes for develop (batch 4)
Develop counterparts of the 1.2.x batch-4 fixes in #8144, re-verified against
current develop HEAD.
- GHSA-4rmr-wvjq-qxc2: include/auth.php Basic Auth and guest branches fall
through to the per-page realm check instead of returning early.
- GHSA-j67j-wpm4-9g3x: the pre-dispatch update_policy branch in user_admin.php
and user_group_admin.php requires a CSRF-token POST. The denylist -> allowlist
redesign is tracked for 1.3 in #8143.
- GHSA-2p3x-f5jm-rg6p: the View-Graphs -> poller RCE chain is broken by the
realm check (4rmr), the update_policy guard (j67j) and shell-free webhits (x5pw).
- GHSA-x5pw-cg7j-mj4r: scripts/webhits.pl runs wc through a shell-free list-form open.
- GHSA-9737-rqh3-h7fh: names interpolated into raise_message() now use __esc()
across the UI; URL- and HTML-bearing messages are excluded.
- GHSA-9x9h-2577-9w86: the colordropdown input is built as a node and the label
is no longer round-tripped through parseHTML (the list item already used
createTextNode on develop).
- GHSA-h96j-8xhc-2p3w: remote_agent.php authorizes on $_SERVER['REMOTE_ADDR'],
not get_client_addr(), which honours client-settable proxy headers.
Regression guards under tests/Unit/Security/{Auth,Csrf,Xss,ShellInjection}.
php -l, check-changelog.py and the sink/architectural baselines all pass.
* chore: reference PR #8145 on the batch-4 1.3.0-dev CHANGELOG entries
* security: resolve develop merge - keep id-only xmlerror unescaped (matches #8141 h745 test)
* security(GHSA-j67j): use REQUEST_METHOD POST guard instead of raw \ (hardening-pattern-guard)
* security(GHSA-9737): fix review findings - drop double-encoding in __esc, escape missed name sinks, correct plugins format-arg count
