Dpanel has an arbitrary file read vulnerability
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
dpanel is an open source server management panel written in Go. In versions 1.2.0 through 1.7.2, dpanel allows authenticated users to read arbitrary files from the server via the /api/app/compose/get-from-uri API endpoint. The vulnerability exists in the GetFromUri function in app/application/http/controller/compose.go, where the uri parameter is passed directly to os.ReadFile without proper validation or access control. A logged-in attacker can exploit this flaw to read sensitive files from the host system, leading to information disclosure. No patched version is available as of this writing.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/donknap/dpanel. 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 github.com/donknap/dpanel has shipped for CVE-2025-53363 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-2025-53363 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-2025-53363. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
