CVE-2025-58048
CRITICALPaymenter Vulnerable to Remote Code Execution via Public File Uploads
Blast Radius
paymenter/paymenterReal-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
Paymenter is a free and open-source webshop solution for hostings. Prior to version 1.2.11, the ticket attachments functionality in Paymenter allows a malicious authenticated user to upload arbitrary files. This could result in sensitive data extraction from the database, credentials being read from configuration files, and arbitrary system commands being run under the web server user context. This vulnerability was patched by commit 87c3db4 and was released under the version 1.2.11 tag without any other code modifications compared to version 1.2.10. If upgrading is not immediately possible, administrators can mitigate this vulnerability with one or more of the following measures: updating nginx config to download attachments instead of executing them or disallowing access to /storage/ fully using a WAF such as Cloudflare.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for paymenter/paymenter. 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.
Fix
Update paymenter/paymenter to 1.2.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-58048 is resolved across your whole dependency graph.
Workarounds
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-2025-58048 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-2025-58048. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
