Improper Validation of Unsafe Equivalence in punycode by the idna crate from Servo rust-url allows an attacker to create a punycode hostname that one part of a system might treat as distinct while another part of that system would treat as equivalent to another hostname.

EG Risk 56/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

How it’s computed (value × EchelonGraph’s weight)

Impact severity (EG Severity): CVSS 8.8 of 10. Never the KEV-floored or EPSS-lifted EG Score.
Exploitation40% × 40%

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".

BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it

Data Freshness Timeline

(refreshed 10× in last 7d / 35× in last 30d)

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). Most recent first.

Showing the most recent 92 of 183 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 8 repeat rows among the latest 100 are merged into the row they repeat. The 91 oldest rows on record are not shown and were not checked, so the counts can still include repeats.

What is CVE-2024-12224?
CVE-2024-12224 is a high-severity vulnerability; its CVE record was published on May 30, 2025. Improper Validation of Unsafe Equivalence in punycode by the idna crate from Servo rust-url allows an attacker to create a punycode hostname that one part of a system might treat as distinct while another part of that system would treat as equivalent to another hostname.
When was CVE-2024-12224 made public?
CVE-2024-12224 was made public on December 9, 2024: that is the date its CVE record's CNA, Mozilla Corporation, gives for when the vulnerability was made public. The CVE record itself was published on May 30, 2025. EchelonGraph's copy of the record carries a last-modified date of June 25, 2025; the record at its source may have been updated since.
Is CVE-2024-12224 actively exploited?
CVE-2024-12224 is not currently on CISA's Known Exploited Vulnerabilities catalog. FIRST EPSS estimates a 0.2% probability of exploitation in the next 30 days (11th percentile of EPSS-scored CVEs).
What is the CVSS score of CVE-2024-12224?
CVE-2024-12224 has a CVSS v3 base score of 8.8 (NVD).
How do I remediate CVE-2024-12224?
A fix for CVE-2024-12224 is available: update to the fixed version the vendor names in its advisory. The vendor advisories EchelonGraph has for CVE-2024-12224 are linked in the Vendor Advisories panel on this page.
