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

  - Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.15.2, he Axios     library is vulnerable to a Prototype Pollution Gadget attack that allows any Object.prototype pollution     in the application's dependency tree to be escalated into surgical, invisible modification of all JSON API     responses  including privilege escalation, balance manipulation, and authorization bypass. The default     transformResponse function at lib/defaults/index.js:124 calls JSON.parse(data, this.parseReviver), where     this is the merged config object. Because parseReviver is not present in Axios defaults, not validated by     assertOptions, and not subject to any constraints, a polluted Object.prototype.parseReviver function is     called for every key-value pair in every JSON response, allowing the attacker to selectively modify     individual values while leaving the rest of the response intact. This vulnerability is fixed in 1.15.2.
    (CVE-2026-42044)
