CVE-2023-24676
HIGHCVE-2023-24676 is a high-severity (CVSS 7.2) Code Injection vulnerability in processwire/processwire. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2023-24676 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Arbitrary Code Execution in Processwire
Blast Radius
processwire/processwireReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
An issue found in ProcessWire 3.0.210 allows attackers to execute arbitrary code and install a reverse shell via the download_zip_url parameter when installing a new module. NOTE: this is disputed because exploitation requires that the attacker is able to enter requests as an admin; however, a ProcessWire admin is intentionally allowed to install any module that contains any arbitrary code.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for processwire/processwire. 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.
Remediation status
No patched version of processwire/processwire has shipped for CVE-2023-24676 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
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.
How O3 protects you
O3 pinpoints whether CVE-2023-24676 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-2023-24676. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-24676 in your dependencies?
O3 detects CVE-2023-24676 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
