{"id":"CVE-2026-16477","published":"2026-10-22T15:17:05.817","lastModified":"2026-10-22T19:17:50.770","description":"CleanShot X for macOS insecurely deserializes untrusted data embedded in a .cleanshot project file (editable screenshot annotations). Exploitation requires an attacker to craft a malicious .cleanshot file, deliver it to the target, and have the target open it; the payload then executes automatically during parsing, resulting in arbitrary code execution in the context of the current user. Users who have never opened a .cleanshot file from an untrusted source are not affected by this vulnerability. This vulnerability was fixed in versions: 4.5.2, 4.6.3, 4.7.8 and 4.8.10","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://cert.pl/en/posts/2026/10/CVE-2026-16477","tags":[]},{"url":"https://cleanshot.com/","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
