CVE-2025-32882
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 goTenna v1 devices with app 5.5.3 and firmware 0.25.5. The app uses a custom implementation of encryption without any additional integrity checking mechanisms. This leaves messages malleable to an attacker that can access the message.
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 goTenna v1 device (app 5.5.3, firmware 0.25.5) implements custom encryption without any integrity protection mechanism. This allows an attacker with message access to modify encrypted content (message malleability) without detection, as there is no authentication tag or MAC to verify message integrity.

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.
-
Check device firmware versionAccess the goTenna Mesh device settings or use the goTenna app to view the firmware version. Navigate to Settings > Device Info > Firmware Version.Affected if Firmware version is exactly 0.25.5
-
Check mobile app versionOpen the goTenna mobile application, go to Settings > About or App Info to view the application version number.Affected if Application version is exactly 5.5.3
-
Verify custom encryption configurationInspect the device or app settings for custom encryption or end-to-end encryption configuration. Look for options labeled 'Custom Encryption', 'Private Key', or similar encryption settings.Affected if Custom encryption is enabled without an authentication tag or MAC option present
-
Examine message packets for integrity protectionCapture or inspect outgoing/incoming message packets using a network sniffer or debug logs. Examine the message structure for the presence of an authentication tag, MAC, or signature field appended to the ciphertext.Affected if No authentication tag, MAC, or signature field is present in encrypted messages
You are affected if your goTenna Mesh firmware is 0.25.5 or your goTenna app is 5.5.3 AND custom encryption is being used without any integrity verification mechanism (no MAC or authentication tag visible in message data).

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 dataImplement authenticated encryption (e.g., AES-GCM, ChaCha20-Poly1305) or add a cryptographic MAC/signature to all messages to prevent unauthorized modification.
