More than 12,000 internet-exposed instances of open-source AI agent builder Flowise could be compromised by the ongoing exploitation of the maximum-severity code injection flaw, tracked as CVE-2025-59528, which could lead to remote code execution, reports The Hacker News.
Intrusions involving CVE-2025-59528, which was addressed by Flowise in September, stemmed from a lone Starlink IP address, according to VulnCheck researchers. Harnessing the vulnerability, which was identified and reported by researcher Kim SooHyun, was noted by Flowise to potentially result in the compromise of risky modules, including child_process and fs, as well as subsequent system compromise, file system infiltration, and data theft.
"This is a critical-severity bug in a popular AI platform used by a number of large corporations. This specific vulnerability has been public for more than six months, which means defenders have had time to prioritize and patch the vulnerability," said VulnCheck Vice President of Security Research Caitlin Condon.
