Is CVE-2026-118458 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
A test authentication procedure is distributed in production environments and compares plaintext credentials for specific application codes. An attacker can use default administrative accounts to log in without legitimate credentials and gain privileged access to the target system.Source: acn.gov.it
