CVE-2026-114197: CWE-502: Deserialization of Untrusted Data in Mandiant FLARE capa
Description
Mandiant FLARE capa versions before 10.0.0 contain a deserialization vulnerability that allows arbitrary code execution when processing crafted .viv or .exe.viv workspace files. This vulnerability is identified as CWE-502 and has a high severity rating with a CVSS score of 8.7. The flaw arises from deserializing untrusted data, which can lead to remote code execution under certain conditions.

Technical Analysis
CVE-2026-114197 is a deserialization of untrusted data vulnerability in Mandiant FLARE capa versions prior to 10.0.0. When a specially crafted .viv or .exe.viv workspace file is passed to the capa utility, it can trigger arbitrary code execution due to unsafe deserialization practices. This vulnerability is classified under CWE-502 and carries a high CVSS 4.0 score of 8.7, reflecting its potential impact and complexity of exploitation.
Potential Impact
Successful exploitation of this vulnerability allows an attacker to execute arbitrary code on the system running the vulnerable capa utility. This can lead to full compromise of the host environment where capa is executed. The vulnerability requires user interaction (passing a crafted workspace file) and has a high attack complexity and vector local, indicating that the attacker needs local access or to convince a user to open a malicious file.
Mitigation Recommendations
No explicit patch or remediation details are provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid opening untrusted .viv or .exe.viv workspace files with capa versions prior to 10.0.0.
