CVE-2026-33891 is a high-severity Denial of Service (DoS) vulnerability impacting the `node-forge` (Forge) JavaScript library, specifically versions prior to 1.4.0. The flaw resides in the BigInteger.modInverse() function, where providing a zero value as input triggers an infinite loop, causing the process to hang indefinitely and consume 100% CPU. This vulnerability can be exploited remotely with low attack complexity, leading to a complete loss of availability for affected services. Currently, there is no evidence of active exploitation, nor are any public exploit codes or Metasploit modules available. Community discussion and media coverage regarding this CVE remain minimal.
