Syft is a a CLI tool and Go library for generating a Software Bill of Materials (SBOM) from container images and filesystems. Syft versions before v1.42.3 would not properly cleanup temporary storage if the temporary storage was exhausted during a scan. When scanning archives Syft will unpack those archives into temporary storage then inspect the unpacked contents. Under normal operation Syft will remove the temporary data it writes after completing a scan. This vulnerability would affect users of Syft that were scanning content that could cause Syft to fill the temporary storage that would then cause Syft to raise an error and exit. When the error is triggered Syft would exit without properly removing the temporary files in use. In our testing this was most easily reproduced by scanning very large artifacts or highly compressed artifacts such as a zipbomb. Because Syft would not clean up its temporary files, the result would be filling temporary file storage preventing future runs of Syft or other system utilities that rely on temporary storage being available. The patch has been released in v1.42.3. Syft now cleans up temporary files when an error condition is encountered. There are no workarounds for this vulnerability in Syft. Users that find their temporary storage depleted can manually remove the temporary files.

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.

Exploitation none (CISA Vulnrichment) · Automatable yes (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".

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).
