CVE 描述
Allocation of Resources Without Limits or Throttling vulnerability in phenixdigital phoenix_storybook allows unauthenticated denial-of-service via BEAM atom table exhaustion.
Multiple LiveView event handlers convert user-supplied event parameter strings to atoms using String.to_atom/1 without validation: 'Elixir.PhoenixStorybook.ExtraAssignsHelpers':handle_set_variation_assign/3 interns every key of the psb-assign params map; 'Elixir.PhoenixStorybook.ExtraAssignsHelpers':handle_toggle_variation_assign/3 interns the "attr" value from psb-toggle events; 'Elixir.PhoenixStorybook.ExtraAssignsHelpers':to_variation_id/2 interns elements of "variation_id"; and 'Elixir.PhoenixStorybook.ExtraAssignsHelpers':to_value/4 interns raw string values for attributes declared as :atom or :boolean. BEAM atoms are never garbage-collected, so each unique attacker-controlled string is a permanent allocation. Once the atom table ceiling (~1,048,576 atoms) is reached, the entire BEAM node aborts, taking down all applications running on it.
This issue affects phoenix_storybook from 0.2.0 before 1.1.0.

EPSS 是一种预测漏洞被利用可能性的评分模型。
EPSS 评分
EPSS 模型生成一个介于 0 到 1（即 0% 到 100%）之间的概率评分。评分越高，漏洞被利用的可能性越大。
EPSS 百分位
百分位用于根据 EPSS 评分对 CVE 进行排名。例如，EPSS 百分位为第 95 的 CVE，其被利用的可能性高于 95% 的其他 CVE。因此，百分位可用于比较不同 CVE 的 EPSS 评分。
