"The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-7476-1 advisory.

    It was discovered that Scrapy improperly exposed HTTP authentication

    credentials to request targets, including during redirects. An attacker

    could use this issue to gain unauthorized access to user accounts. This issue only affected Ubuntu 18.04
    LTS and Ubuntu 20.04 LTS. (CVE-2021-41125)

    It was discovered that Scrapy did not remove the cookie header during cross-domain redirects. An attacker
    could possibly use this issue to gain unauthorized access to user accounts. This issue only affected
    Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-0577)

    It was discovered that Scrapy inefficiently parsed XML content. An attacker could use this issue to cause
    a denial of service by sending a crafted XML response. This issue only affected Ubuntu 18.04 LTS, Ubuntu
    20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-1892)

    It was discovered that Scrapy did not properly check response size during decompression. An attacker could
    send a crafted response that would exhaust memory and cause a denial of service. This issue only affected
    Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-3572)

    It was discovered that Scrapy did not remove the authorization header during cross-domain redirects. An
    attacker could possibly use this issue to gain unauthorized access to user accounts. This issue only
    affected

    Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-3574)

    It was discovered that Scrapy did not remove the authorization header during redirects that change scheme
    but remain in the same domain. This issue could possibly be used by an attacker to expose sensitive

    information or to gain unauthorized access to user accounts. (CVE-2024-1968)
