DiscordChatExporter saves Discord chat logs to a file. Prior to 2.47.2, HTML exports generated with markdown formatting disabled pass attacker-controlled content through FormatMarkdownAsync and FormatEmbedMarkdownAsync in DiscordChatExporter.Core/Exporting/MessageGroupTemplate.cshtml and render it without HTML entity encoding. The affected fields include message.Content, message.ForwardedMessage.Content, message.ReferencedMessage.Content, embed.Title, embed.Description, field.Name, and field.Value. A Discord webhook or bot can store a script payload in these fields, and the payload executes when a user exports the channel with markdown formatting disabled and opens the resulting HTML, allowing the script to read the export or alter its displayed content. This issue is fixed in version 2.47.2.

EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).
