CVE-2026-50226
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 · uneditedFixed AES-128-CBC keys inside the AcerConnect OTA application let attackers forge authorization credentials for arbitrary IMEI numbers. This allows unauthorized actors to list catalog items and extract protected binaries from pre-signed cloud links.
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 · moderate confidenceThe AcerConnect OTA application uses hardcoded AES-128-CBC keys for encrypting authorization credentials. Attackers who obtain these fixed keys can craft valid authentication tokens for any IMEI number by encrypting the appropriate data structures, bypassing the legitimate authorization mechanism and gaining access to protected catalog information and pre-signed cloud download links.

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.
-
Identify device modelCheck the device label, management interface, or system information for the exact model name. Confirm it is the Acer Connect M6e 5g device.Affected if The device is not an Acer Connect M6e 5g unit.
-
Retrieve firmware versionAccess the device's admin console, check system settings, or use the command 'cat /proc/version' or 'ver' via UART/Telnet/SSH to obtain the installed firmware version string.Affected if The firmware version cannot be determined or the device is not running the Acer Connect OTA application.
-
Compare version against affected rangeCompare the installed firmware version to the affected range m6e_ai_1.00.000019. Versions numbered lower than or equal to this release are vulnerable.Affected if The installed firmware version is m6e_ai_1.00.000019 or earlier.
-
Inspect OTA application for static keysIf you have access to the firmware image or device filesystem, examine the OTA update binary or application files for hard-coded AES-128-CBC keys. Search for static key strings or examine cryptographic initialization code.Affected if Hard-coded AES-128-CBC keys are present in the OTA application binary or configuration.
-
Verify token forgery is possibleAttempt to generate an authentication token for a known IMEI using the OTA application's token generation logic. If tokens can be created for arbitrary IMEIs without access to dynamic key material, the vulnerability is present.Affected if Authentication tokens can be forged for any IMEI number using the application's built-in logic.
Your environment is affected if you are running Acer Connect M6e 5g firmware version m6e_ai_1.00.000019 or earlier, or if hard-coded AES-128-CBC keys are found in the OTA application.

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 dataReplace hardcoded AES-128-CBC keys with dynamically generated per-device or per-session keys stored in a secure key management system; implement proper token validation using asymmetric cryptography or HMAC with secret rotation; audit and rotate any potentially exposed credentials.
