Linux Distros Unpatched Vulnerability : CVE-2026-44293

high Nessus Plugin ID 320653

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs generated JavaScript for toObject conversion could include an unsafe expression derived from a schema-controlled bytes field default value. A crafted descriptor with a non-string default value for a bytes field could cause attacker-controlled code to be emitted into the generated conversion function.
 This vulnerability is fixed in 7.5.6 and 8.0.2. (CVE-2026-44293)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
