Threats Tagged 'cve-2026-4359'

CVE-2026-4359 is a low-severity vulnerability in the MongoDB C Driver caused by improper neutralization of null byte characters (CWE-158). An attacker, such as a compromised third-party cloud server or a man-in-the-middle, can send a malformed HTTP response containing null bytes that triggers a crash in applications using this driver. Exploitation requires high privileges and user interaction, and the attack complexity is high. There are no known exploits in the wild, and no patches have been released yet. The vulnerability primarily impacts the availability of applications relying on the MongoDB C Driver by causing crashes, but it does not affect confidentiality or integrity. Organizations using this driver in their infrastructure should monitor for updates from MongoDB Inc and consider network-level protections to mitigate man-in-the-middle risks. Countries with significant MongoDB usage and cloud infrastructure reliance are more likely to be affected. Overall, the threat is limited in scope and impact but should be addressed to maintain service stability.
