Cisco released fixes for nine vulnerabilities across its Crosswork network-automation platforms and Secure Workload software, five of them rated 10.0. Four affect Crosswork Data Gateway, Network Controller, and Planning regardless of configuration, and include a SQL injection flaw, a missing-authentication flaw, and external control of the file system, each scored 10.0, plus an insufficiently protected credentials issue at 9.9. Five more affect Secure Workload in both cloud and on-premises deployments, led by a 10.0 improper access control flaw and a 9.9 command-injection flaw. Cisco found them in internal testing using AI models and says none are exploited yet, but there are no workarounds, so patching is the only fix.
Fortinet patched two critical RCE flaws Tuesday. CVE-2026-44277 in FortiAuthenticator (Fortinet's IAM/MFA platform) lets unauthenticated attackers execute code via crafted requests. CVE-2026-26083 (CVSS 9.1) in FortiSandbox's web UI lets unauthenticated attackers run code via HTTP requests. Neither is confirmed exploited yet, but Fortinet products have a long exploitation history - CISA flagged FortiClient EMS as actively exploited in April. FortiSandbox is the threat-detection backbone for many Fortinet-centric SOCs; FortiAuthenticator gates MFA and SSO.
Researchers disclosed CVE-2026-3854, a critical GitHub Enterprise Server flaw that lets anyone with push access execute arbitrary commands on the GitHub server with a single git push. The bug is in how Enterprise Server handles repository hooks during push operations - a crafted commit message or filename bypasses the sanitization that normally prevents shell injection. GitHub patched it last week, but self-hosted instances need to apply the patch manually, and telemetry shows most haven't yet. Anyone with developer-level access to a vulnerable Enterprise Server can take over the entire instance, then pivot into every repository and CI/CD secret it hosts.
CrowdStrike disclosed CVE-2026-40050 on April 21, a critical unauthenticated path traversal in a specific cluster API endpoint of self-hosted LogScale (formerly Humio). CVSS 9.8. A remote attacker who can reach the endpoint can read arbitrary files from disk - including config files, certificates, embedded credentials, and the very logs the platform was deployed to protect. CrowdStrike found the bug through internal product testing and applied network-layer blocks across all SaaS clusters on April 7. Self-hosted customers must patch themselves. There is no evidence of in-the-wild exploitation yet.
