CVE-2026-24711: 
CFEngine vulnerability analysis and mitigation

CVE-2026-24711 is an Incorrect Access Control vulnerability in Northern.tech CFEngine Enterprise, a configuration management platform. It affects CFEngine Enterprise versions before 3.21.8, versions 3.24.0 through before 3.24.3, version 3.26.0, and versions before 3.27.0. The vulnerability was published on May 14, 2026, and has a CVSS v3.1 base score of 5.3 (Medium) (GitHub Advisory, CFEngine Blog).

The vulnerability is classified as CWE-284 (Improper Access Control), meaning the product does not correctly restrict access to a resource from an unauthorized actor. It is exploitable remotely over the network with low attack complexity, requires no privileges, and no user interaction — making it accessible to unauthenticated remote attackers. The specific access control mechanism that is bypassed has not been publicly detailed beyond the vendor advisory, but the impact is limited to low confidentiality exposure with no integrity or availability impact (GitHub Advisory, CFEngine Blog).

Successful exploitation allows an unauthenticated remote attacker to gain unauthorized read access to information within the CFEngine Enterprise environment. The confidentiality impact is rated as low, with no impact to integrity or availability. Because CFEngine Enterprise manages infrastructure configuration at scale, even limited unauthorized information disclosure could expose sensitive configuration data, policy details, or system inventory that could aid further attacks (GitHub Advisory).

No public proof-of-concept exploit code or in-the-wild exploitation has been reported for CVE-2026-24711 as of the available data. The EPSS score is approximately 0.018% (0.039% per GitHub Advisory), placing it in the 12th percentile for exploitation likelihood within 30 days. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and no threat actor attribution has been identified (GitHub Advisory).

Northern.tech has released patched versions of CFEngine Enterprise addressing this vulnerability. Users should upgrade to version 3.21.8 or later (for the 3.21.x branch), 3.24.3 or later (for the 3.24.x branch), or 3.27.0 or later. No specific configuration-based workarounds have been publicly documented; upgrading to a fixed version is the recommended remediation (CFEngine Blog, GitHub Advisory).

Northern.tech published a blog post addressing CVE-2026-24711 alongside two related CVEs (CVE-2026-24710 and CVE-2026-24712), indicating a coordinated disclosure of multiple access control issues in CFEngine Enterprise.
