Versions 1.3.312 and below have untrusted executable search path / binary hijacking vulnerability that allows a local attacker to execute arbitrary code when the affected Windows application launches explorer.exe without using an absolute path. The vulnerable behavior is triggered when the user double-clicks the application’s tray icon, which opens the directory containing the most recent screenshot captured by the application. By placing a malicious executable with the same name in a location searched prior to the legitimate Windows binary, an attacker can gain code execution in the context of the application. This issue did not have a patch at the time of publication.","severity":{"version":"3.1","score":6.5,"vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.002,"percentile":0.09956,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-426"],"published":"2026-03-20T10:04:34Z","modified":"2026-10-28T02:30:37Z","products":[{"vendor":"getgreenshot","product":"greenshot"},{"vendor":"greenshot","product":"greenshot"}],"references":[{"url":"https://github.com/greenshot/greenshot/security/advisories/GHSA-f8v9-7fph-fr2j","tags":["x_refsource_CONFIRM","Exploit","Mitigation","Vendor Advisory","advisory"]},{"url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25792.json","tags":["advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25792","tags":["advisory"]}],"sources":{"cve":[{"id":"CVE-2026-25792","title":"Greenshot Vulnerable to OS Command Injection via ExternalCommand Plugin","description":"Greenshot is an open source Windows screenshot utility.
