How do I fix CVE-2023-47636?

Update pimcore/admin-ui-classic-bundle to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-47636 is resolved across your whole dependency graph.

How do I detect CVE-2023-47636 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pimcore/admin-ui-classic-bundle. 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.

How do I mitigate CVE-2023-47636 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2023-47636?

O3 pinpoints whether CVE-2023-47636 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2023-47636 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-47636, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2023-47636?

CVE-2023-47636 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 46th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2023-47636?

CVE-2023-47636 is classified as CWE-209 (CWE-209). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2023-47636 published, and has it been updated?

CVE-2023-47636 was published on November 15, 2023 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-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

The Pimcore Admin Classic Bundle provides a Backend UI for Pimcore. Full Path Disclosure (FPD) vulnerabilities enable the attacker to see the path to the webroot/file. e.g.: /home/omg/htdocs/file/. Certain vulnerabilities, such as using the load_file() (within a SQL Injection) query to view the page source, require the attacker to have the full path to the file they wish to view. In the case of pimcore, the fopen() function here doesn't have an error handle when the file doesn't exist on the server so the server response raises the full path "fopen(/var/www/html/var/tmp/export-{ uniqe id}.csv)". This issue has been patched in commit 10d178ef771 which has been included in release version 1.2.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
