CVE-2026-71232

HIGH

CVE-2026-71232 is a high-severity (CVSS 7.2) Code Injection vulnerability. O3 Security confirms whether CVE-2026-71232 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

MacCMS10's admin template editor (application/admin/controller/Template.php) blocks dangerous PHP functions in template content via a blacklist regex, but the blacklist omitted exec, passthru, popen, show_source, create_function, register_shutdown_function, register_tick_function, and error_log. Combined with ThinkPHP's {if} template tag, which embeds the condition attribute directly into raw PHP (<?php if(condition): ?>), an authenticated administrator could inject a payload such as {if condition="exec('id > /tmp/pwned.txt')"}{/if} to achieve remote code execution. Fixed in commit 71ad3bb29570e110d8e973acff68040a3050ddf0 (2026-06-22), which added the missing functions to the filter.

Detection & mitigation playbook

Vulnerability
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Remediation status

    No patched version of the affected component has shipped for CVE-2026-71232 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether CVE-2026-71232 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to CVE-2026-71232. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
