CVE-2026-2449

CVE-2026-2449 is an argument injection vulnerability in upKeeper Solutions' upKeeper Instant Privilege Access software through version 1.5.0 that allows attackers to improperly neutralize command argument delimiters and hijack privileged threads of execution. This vulnerability enables attackers with appropriate access to manipulate command arguments and gain control over high-privilege processes within the application. The vulnerability carries a FAUCET Risk Score of 52.0/100 and an EPSS score of 0.000790000, indicating moderate concern within the security community. While specific CVSS metrics are not yet published, the nature of the vulnerability as an argument injection attack targeting privilege escalation mechanisms suggests it could have significant impact on system security if successfully exploited. There is currently no evidence of active exploitation in the wild, as the vulnerability is not present in the Known Exploited Vulnerabilities catalog. The EPSS score and moderate risk rating indicate this remains a lower-priority threat compared to actively exploited vulnerabilities, though organizations running affected versions of upKeeper Instant Privilege Access should plan remediation efforts and update to version 1.5.1 or later when available.
