Nuclei is a vulnerability scanner powered by YAML based templates. Starting in version 3.0.0 and prior to version 3.3.2, a vulnerability in Nuclei's template signature verification system could allow an attacker to bypass the signature check and possibly execute malicious code via custom code template. The vulnerability is present in the template signature verification process, specifically in the signer package. The vulnerability stems from a discrepancy between how the signature verification process and the YAML parser handle newline characters, combined with the way multiple signatures are processed. This allows an attacker to inject malicious content into a template while maintaining a valid signature for the benign part of the template. CLI users are affected if they execute custom code templates from unverified sources. This includes templates authored by third parties or obtained from unverified repositories. SDK Users are affected if they are developers integrating Nuclei into their platforms, particularly if they permit the execution of custom code templates by end-users. The vulnerability is addressed in Nuclei v3.3.2. Users are strongly recommended to update to this version to mitigate the security risk. As an interim measure, users should refrain from using custom templates if unable to upgrade immediately. Only trusted, verified templates should be executed. Those who are unable to upgrade Nuclei should disable running custom code templates as a workaround.

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.

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".

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. 4 repeat rows among the latest 100 are merged into the row they repeat. The 113 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
