Additional Ivanti Connect Secure zero-days exploited in the wild (CVE-2026-111357, CVE-2026-118527)


On October 29, 2026, Ivanti updated its security advisory for Ivanti Connect Secure (ICS) to include two additional vulnerabilities and released fixes for both. Ivanti rates CVE-2026-111357, a missing authentication for critical function vulnerability (CWE-306), with a CVSSv3.1 score of 8.8; it allows a local authenticated attacker to escalate privileges. CVE-2026-118527, classified as generation of predictable numbers or identifiers (CWE-340), has an Ivanti-assigned CVSSv3.0 score of 4.3 and, according to CISA’s KEV entry, allows a remote authenticated attacker to upload attacker-controlled content to a known location on disk.

Per Ivanti, exploitation in the wild has already occurred prior to disclosure, affecting a limited number of customers when these flaws are chained with CVE-2026-104935, an authentication bypass by spoofing (CWE-290). Rapid7 covered the original disclosure on October 13, 2026, when a fix for CVE-2026-104935 was available but the privilege escalation component remained unpatched. Fixes are now available for all three vulnerabilities.
