The application loads a network plugin without validating its digital signature or verifying its authenticity. A local attacker can exploit this behavior by placing a malicious component in the expected location, which is controllable by the attacker (e.g., under %APPDATA%), resulting in code execution within the context of the user. The main application is digitally signed, which may allow a malicious component to inherit trust and evade detection by security solutions that rely on signed parent processes.","severity":{"version":"3.1","score":6.1,"vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","level":"medium","assessor":"adp","from":"cve"},"epss":{"day":"2026-11-12","score":0.00164,"percentile":0.0571,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-77"],"published":"2025-10-21T00:00:00Z","modified":"2026-11-05T22:10:00Z","references":[{"url":"https://github.com/bambulab/BambuStudio/issues/7405"},{"url":"https://github.com/piuppi/Proof-of-Concepts/blob/main/Bambu%20Lab/Bambu%20Studio/README.md"},{"url":"https://wiki.bambulab.com/en/software/bambu-studio/release/release-note-2-3-0"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2025-57521"},{"url":"http://bambu.com"},{"url":"https://github.com/advisories/GHSA-mgv2-737c-m3c7"}],"sources":{"cve":[{"id":"CVE-2025-57521","description":"Bambu Studio 2.1.1.52 and earlier is affected by a vulnerability that allows arbitrary code execution during application startup.
