CVE 描述
Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws
Cpanel::JSON::XS versions before 4.41 for Perl allow denial of service via UTF-8 BOM prefixed input when a decode filter callback throws. To skip a leading 3-byte UTF-8 BOM, decode_json() advances the input scalar's string pointer past the mark with SvPV_set() and restores it only on the normal return path. When decoding aborts through a Perl exception, for example a filter_json_object callback that croaks, the restore is skipped and the scalar is left with its string pointer offset into its own buffer and a shortened length. When that scalar is later freed, the allocator receives an invalid pointer and the interpreter aborts. A single BOM prefixed document decoded with a throwing filter callback crashes any caller.CVE 解決方案
Upgrade to Cpanel::JSON::XS 4.41 or later.

EPSS
EPSS 是一種預測漏洞被利用可能性的評分模型。
EPSS 評分
EPSS 模型產生介於 0 到 1（0% 到 100%）之間的概率分數。分數越高，漏洞被利用的概率越大。
EPSS 百分位數
百分位數用於根據 EPSS 分數對 CVE 進行排名。例如，EPSS 評分在第 95 百分位的 CVE 比 95% 的其他 CVE 更有可能被利用。因此，百分位數用於比較某 CVE 的 EPSS 分數與其他 CVE 的相對位置。
