OpenCATS is an open-source applicant tracking system and recruitment CRM for staffing agencies and hiring teams. Prior to 0.10.0, the OpenCATS Import module in modules/import/ImportUI.php can preserve an uploaded file's original name for one import data type and place the file in the web-accessible temporary directory. An authenticated user with Import privileges can select the affected import path and upload a PHP file that remains under an attacker-controlled executable filename, and an import error can leave the file on disk. If the temporary directory is served with PHP execution enabled, requesting the staged file can execute arbitrary PHP code with the web server process privileges, exposing or modifying recruiting data and the host system. This issue is fixed in version 0.10.0.

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".
