CVE-2026-33449
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 · uneditedCVE-2026-33449 is a buffer overflow in a message handling function of the Secure Access client prior to 14.50. Attackers with control of a modified server can send a cryptographically valid message to the client, overwriting a small portion of memory conceivably leading to a denial of service.
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 buffer overflow exists in a message handling function of the Secure Access client versions prior to 14.50. An attacker controlling a modified server can send a cryptographically valid message to the client, causing a small memory overwrite that may lead to denial of service.

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 installed Secure Access client versionOpen the Secure Access client application and navigate to Help > About, or check the installed programs list in Windows Control Panel > Programs and Features to locate the Absolute Secure Access client entry and its version numberAffected if The displayed version is any version prior to 14.50 (for example, 14.40, 14.30, 14.0, 13.x, or lower)
-
Verify client version via command line or installerIf available, run the command 'secureaccess --version' or 'secureaccess -v' from a command prompt, or examine the installer package used to deploy the clientAffected if The command returns a version number lower than 14.50 or the installer version is dated before the 14.50 release
-
Confirm client is configured for server communicationOpen the Secure Access client settings and check if connections to remote servers are enabled, or review the client configuration profile for any active server connection settingsAffected if The client has active server connection profiles or is configured to connect to any server (which would allow a modified server to send the malicious message)
A user is affected if their installed Absolute Secure Access client version is below 14.50 and the client has active server communication enabled.

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.
dbcve · scoped14.50
