CVE-2020-26603
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered on Samsung mobile devices with O(8.x), P(9.0), and Q(10.0) software. Sticker Center allows directory traversal for an unprivileged process to read arbitrary files. The Samsung ID is SVE-2020-18433 (October 2020).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA directory traversal vulnerability in the Sticker Center application on Samsung mobile devices running Android O(8.x), P(9.0), and Q(10.0) allows an unprivileged process to read arbitrary files on the device by traversing outside the intended sticker directory. This is a local information disclosure vulnerability with CVSS 5.3 indicating moderate severity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device is SamsungCheck the device manufacturer by going to Settings > About Phone > Manufacturer or by running 'getprop ro.product.manufacturer' via ADBAffected if Device is not manufactured by Samsung, then this specific app vulnerability does not apply
-
Confirm Android version is affectedGo to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via ADBAffected if Android version is 8.0, 8.1, 9.0, or 10.0 - versions outside this range are not affected
-
Verify Sticker Center app is installedCheck for Samsung Sticker Center app in the app drawer, or list installed packages via ADB: 'pm list packages | grep -i sticker'Affected if Sticker Center application is present on the device - if not installed, the vulnerability cannot be exploited
User is affected if running a Samsung device with Android 8.0-10.0 that has the Sticker Center application installed, as the directory traversal flaw exists in that specific app's file access validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataThis vulnerability requires a vendor patch from Samsung to fix the Sticker Center application's file access validation. Users should apply official firmware/security updates when available. No user-side workarounds exist for this app-level vulnerability.
