The application, which typically operates with high-level system privileges, attempts to perform an internal validation check by invoking a secondary system utility using an unqualified file reference.\n\n\n\nBecause the application does not specify an absolute path to this utility, it relies on the operating system's default search order to locate the executable. Under specific conditions, a local attacker with the ability to modify directories within the system's search path could plant a malicious binary that mimics the expected utility. This could result in the malicious code being executed with SYSTEM privileges, leading to a full compromise of the affected host.","published_at":"2026-06-22T03:24:06.542000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.3,"cvss_v4_vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-427"],"nvd_references":["https://www.papercut.com/kb/Main/papercut-ng-mf-security-bulletin-june-2026/"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:31:02.463961Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"P","value_label":"Passive"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"H","value_label":"High"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"H","value_label":"High"},{"metric":"SA","name":"Availability (Subsequent System)","value":"H","value_label":"High"}]},"affected":[{"vendor_slug":"papercut","vendor_name":"PaperCut","product_slug":"print-deploy","product_name":"Print Deploy","version_start":"0","version_start_inclusive":true,"version_end":"1.10.4178","version_end_inclusive":false,"cpe23_uri":"cve5:papercut:print-deploy:0:1.10.4178"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.papercut.com/kb/Main/papercut-ng-mf-security-bulletin-june-2026/","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-22T03:24:06.542000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:56:06.764790Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:56:06.764790Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:56:06.764790Z","label":"CVSS score revised","source":"cvelistv5"}]}
