DiscordChatExporter saves Discord chat logs to a file. Prior to 2.47.2, the VisitEmojiAsync method in DiscordChatExporter.Core/Exporting/HtmlMarkdownVisitor.cs interpolates emoji.Name into the alt attribute and emoji.Code into the title attribute without HTML entity encoding. This affects HTML exports regardless of the markdown setting. Discord's current custom emoji name validation normally excludes attribute-breaking characters, but tampered offline input, a relaxed upstream validation rule, or another future metadata source can inject an HTML attribute and execute script when a user opens the export. 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 public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (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".
