  - A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser
    mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing
    strings to Time objects. The fixed versions are 0.1.1 and 0.2.2. (CVE-2023-28756)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
