requests. An attacker could possibly use this issue to inject arbitrary

Javascript code, resulting in denial of service or potential execution of

arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04

LTS, Ubuntu 22.04 LTS and Ubuntu 24.04 LTS.

(CVE-2018-25047, CVE-2023-28447)

use this issue to execute arbitrary code. (CVE-2024-35226)
