    call. An attacker could possibly use this issue to obtain potentially sensitive server information.
    (CVE-2020-25633)

    It was discovered that RESTEasy improperly populated exception responses with endpoint class and method
    names. An attacker could possibly use this issue to obtain potentially sensitive server information.
    (CVE-2021-20289)

    It was discovered that RESTEasy used improper permissions when creating temporary files. An attacker could
    possibly use this issue to get access to sensitive data. (CVE-2023-0482)

    It was discovered that RESTEasy improperly handled certain HTTP requests containing ASCII control
    characters. An attacker could possibly use this issue to cause a denial of service. (CVE-2024-9622)
